Lag time – don’t miss the shot

Lag time - test one

• Lag time – test one •

Every time you push the button…

There’s a period when not much happens. Lag time is the total time taken for the camera to complete the exposure process from the button push. In that process is a lot of detail. Here we look at lag time. With a simple test you can get a feel for the lag time in your camera.

Why is lag time important?

If you buy a camera for action shots you want minimal lag time. Otherwise you look and press, but the action has gone. Of course you can anticipate the action. This is how we all deal with lag time. But to know what time to anticipate you need a feel for the camera. A long lag time is likely to make your guess about when to press the shutter button less accurate. So it’s in your interest to know the lag time and practice with it. If you know the lag it makes it easer to guess the delay for shots.

Shutter lag – don’t misuse the term

Some people use the term shutter lag in a confusing way. They mean it to be the same as lag time. In the past this may have been the case. In early cameras most of the exposure process was completed by the shutter. Today we have a lot of other steps involved. The list of various time related things in the exposure process is quite long today…

  1. LCD activation of the picture (LCD display and electronic [mirrorless] viewfinders only).
  2. Thinking time between seeing a subject on the display and the finger push on the button.
  3. Time taken to get a focus.
  4. Aperture – time to calculate & set aperture size.
  5. Meter – time from light reading to exposure set up.
  6. Digital sensor start up to be ready.
  7. Shutter motor/mechanism actuation.
  8. Shutter opening.
  9. Digital capture of light data.
  10. Shutter closing.
  11. Data emptied from sensor ready for next exposure.

These items may overlap, run simultaneously or be in sequence. Some may not apply to some cameras. It depends on the camera model, design, efficiency and the components involved.

This list adds up to the total lag time. The first five items are not shutter related. They delay the firing of the shutter. They are shutter delay times. The other items are shutter lag items. They are responsible for the shutter and sensor capture of the exposure. They determine the shutter process from start to finish. These are the shutter lag items.

To be clear, lag time is the sum of all the lag items. Shutter lag is only those items related to the shutter-sensor system.

For a more detailed look at various components of lag times check out: Definition: Shutter lag; Shutter delay; Lag time; Processing lag;

Getting the shot – lag time explored

In order to know your camera better you can actually measure your lag time. So here is a method you can use at home. I have tested it using two different pieces of equipment and on two cameras with good results.

A word of warning. The on-board flash crosses all the other lag/delay times and may extend your total lag quite a lot. This is because it takes time to charge up ready for the flash. It will affect the results. Before testing turn off your flash. Check your manual if you are not sure how. Both these methods have back-lighting. You will get enough light without it.

Explanation/method: to measure the lag time we need to identify all the processes involved. I have done this for you above. This allows you to know what parts of the process are holding things up. You will see later that can help you save time.

Next we need to find a way to mark the start and end of the process. Fortunately the camera helps us. When the shutter button is pushed we know the exposure process is started. The clever part is that if we photograph a timer we know when the exposure process is finished because the clock will show the finish time.

To find out our lag time is easy. We activate a clock at the same time as we push the shutter button. We do this while photographing the clock. When the shot is taken the end of the the lag time is shown on the photograph.

Two methods to try out

In the photo “Test one” above I have used this method with my smart phone. I set up the stop-watch app on my phone. Then I pushed “start” with my left hand. I simultaneously held the camera and pushed the shutter button. The key is to make sure you set off both the timer and shutter button at once. If you do, the the photograph will show the lag time. In the photo above it shows 69/100ths of a second. This is my lag time for a photo taken on my little Canon G12. Use a tripod or stand if holding your camera and pushing the button at once is not steady enough.

If you do not have a smart phone (or a stop watch) to photograph, try this web page…
This page will allow you to test your Digital Camera’s shutter lag… External link - opens new tab/page.
(Note: this page is about your total lag time even though it refers to the shutter lag).

Shutter Lag Test two

• Shutter Lag Test two •
Test your Digital Camera’s lag time External link - opens new tab/page.

Follow the instructions on that page. You will see a very slight retard on the clock at the ‘zero’ point. That gives you time to notice the top point and press the shutter button. The resulting photo will tell you the lag time on your camera.

I have run tests on my camera using both the web page and the stop-watch app method. They give consistent results. I feel confident you will find either test will work for you.

Pre-focus to get the shot

Notice on the second test page there are two tests. The second one shows you how you can shorten your lag time. If you pre-focus the camera that saves some pre-shutter time. Focus takes quite a bit of time. So if it is already focused when you take the shot your lag is reduced.

To reduce the delay with pre-focus press the button half way down while looking at the clock. The camera will focus and take meter reading. Then you can hold the half way position – this is called focus-lock. Hold your half-down position until, at zero. Then push the shutter button the rest of the way down. You will normally find your camera lag time is greatly reduced. Possibly by as much as a half. Something to bear in mind for future shots.

Accuracy

Of course you might take a totally bad reading for your fist shot. After playing I found that for both methods you need to practice a little to get consistent readings.

To ensure you get a good overall result I suggest taking ten readings after some practice. Here are readings from my run of ten… 0.53 + 0.53 + 0.69 + 0.98 + 0.89 + 0.66 + 0.74 + 0.65 + 0.66 + 0.74 = 7.07
If we divide the total by ten we will get an average reading. It will iron out any anomalous readings.
Thus: 7.07÷10 = 0.71 (rounded to two places). The lag time on this camera is therefore 71/100ths of a second.

This ‘average’ method provides us with a consistent standard over our readings. This is a more accurate method of gauging the lag time.

What have we done?

The things a modern camera does to take a picture has created a long lag. The lag time is the sum of all the different things that impact the exposure process. From button-press to complete capture-of-data is the lag time.

We have looked at two ways of testing the lag time: a stop watch app; and a web page timer. I have also suggested using an average reading to iron out anomalies.

If you go through this process you will know your camera much better. But more to the point you will have a new confidence. You will know how long it takes to complete an exposure. And, you will know how much time to delay for a shot.

On-camera flash… advice for taming the beast

Taming on-camera flash

• Taming on-camera flash •
Left: harsh light and highlights are so unflattering!
Right: properly controlled you get proper skin tones and no highlights.
•••••||•••••
On camera flash can be a pretty tough nut to crack – learn how.
(Images taken from the video)

On-camera flash is pretty harsh…

In fact it’s often the source of ruined pictures from otherwise great dinner parties and family events. Dealing with with these little beasts takes a little work. You can make them do you bidding, you just need to know how.

A small powerful light source

The power of the little flash on your camera is misleading. For such a small light it puts out a lot of power. The learner is often caught off-guard. A great scene can be ruined by very unpleasant light, colour leached from faces, shiny reflections on faces and really hard-edged shadows. The whole thing is pretty ugly.

Here is some news. There are ways to control these little beasts and make them do your bidding.

Two of the most useful techniques for dealing with the problems are explained more fully in: Find out more about diffusing your on-camera flash. The other way is to help your flash work better in the room. Use the room itself as a way to bounce light around. Point your flash at a wall or ceiling so the light is reflected everywhere. It will make harsh flash into soft light – make it a more wrap-around light. This is always more flattering and shows the gentle curves of the face much better. It also means the light works its way around the back of the subject reducing harsh shadows cast onto the wall.

Practical use of the on-camera flash

For those quiet evenings where you are chatting with your friends and family here are some easy techniques. You can use your on-camera flash to good effect without the harsh shadows. You can escape the electric shock faces and startled expressions too. Have a look at the video and follow the sage advice of Mike Browne at a dinner party…

Using the proper tools is best

Let’s face it. On-camera flash is always going to be a bit difficult. As good as it looks in the video controlled results are always going to be difficult from such a little light source. Here is what Mike himself has to say about on-camera flash…

I’d suggest a speedlight is better because you can fit a diffuser and better still, turn the flash head in any direction and bounce the flash off a wall or ceiling.

Umbrellas and softboxes

umbrellas and softboxes

• Softbox Vs. Umbrella •
Umbrellas and softboxes seem to have similar characteristics… or do they?

What IS the difference?

Photographers learning to use lights find it difficult to understand the difference between a softbox and umbrella set-up. It is important to understand if you want to have control of light.

The nature of soft and hard light

Hard light is not some mutated form of ordinary light. It is a type of light that is focussed and which shows a hard transition from bright to dark. The shadow line is a sharp contrast. On the other hand, soft light wraps itself around curves and has a soft transition from light to dark.

The definitions of hard and soft light tell us much about the characteristics of the light but not how the light is formed. Well, it turns out that the light source, its shape, size and focus or diffusion as well as distance from the subject all have an impact on the characteristics of light.

Photographic umbrellas and softboxes

In the video Mark Cleghorn examines the characteristics of photographic umbrellas and softboxes. He does some great shots with both. Pay attention to the way he uses the lights and what characteristics he points out. Distance and size of the sources play an essential role in the formation of the softness and hardness of the light. His experiments are interesting and show you how the nearness of a large light source can create softness. It seems counter intuitive, but it is correct.

The first half of this video is very useful and you will learn a lot about Umbrellas and softboxes as light sources. The second half showcases advanced features of Photoshop. This is a less useful section if you are only interested in the practical issues for umbrellas and softboxes. You can safely skip it.

Types of lights

There are many types of light source that can generate light for umbrellas and softboxes. For most situations it is best to use off-camera flash units. The more expensive studio flash units are more for professional use. If you are just starting out they will be more powerful than required for most general purpose needs. Off camera flash helps give you flexible use. It is also easily controlled. You can work with both umbrellas and softboxes with an off camera flash.

Fortunately, most umbrellas and softboxes units designed for off-camera flash will mount most types of flash units. When looking to purchase lights think about what you want to achieve. Then buy the flash unit needed to meet your need.

Below is an example of a photographic umbrella set…

DynaSun W968S Professional Kit with Holder, Umbrella, Stand and Bag for Cold Shoe Mount Flash Gun Flashgun  External link - opens new tab/page
This is a high quality but affordable photographic umbrella unit. The complete package includes everything you need except the off-camera flash unit. The inclusion of the small carrying bag makes the whole thing neat and well presented.

When it comes to the purchase of a soft box these too have the universal fittings for off camera flash units (although studio units are also available). Here is an example softbox…

24″ 60cm x 60cm EZ-Fold Studio Softbox Kit with 2 x Diffusers and Ballhead Bracket for Portable Flash and Speedlite  External link - opens new tab/page
This is a high quality, well produced softbox with easily adjustable fittings and a variety of ways to set up light diffusion within the unit.

Of course both these units are among many others in the field. You can see the various types of each on these search pages…

Softboxes – search page on Amazon

These various examples include studio light units, always on bulb mountings and fittings for off-camera flash. Check for what you want before you buy. The most flexible is for off-camera flash when you are starting out.

No removable flash? Read this: Off-camera flash. It’s a great introduction and recommends an affordable flash unit.

Visual toolbox for photographers

Sharpen up your creative photography…

It’s easy when starting photography to over emphasis the importance of gear. In fact it’s ‘photographers eye’ that really makes the difference. Your vision and insight into a scene are critical to producing a wonderful image.

Sage advice from a world master

The Visual Tool Box by David duChemin is all about the skills of composition. He goes into depth around the background ideas which help you look at a scene. The ultimate success in photography is to make your image a pleasure to view. Aesthetics rule – it’s as simple as that. This book is dedicated to teaching you the tools you need to develop the ‘eye’.

David duChemin says,

These are the lessons I wish I’d learned when I was starting out.
The Visual Tool Box by David duChemin

This is my kind of book. He writes superbly, in simple, readable form. His examples are excellent and the pictures are just amazing. But most of all the book is organised for learners to extend their knowledge in easy, well structured steps. This book is all about putting new tools in your photographic tool box and it achieves that with an ease that any beginner will find a joy.

Composition

The book is packed with examples of the sort of compositional ideas that really work – for anyone. Just look at some of the topics covered…

  • Manual
  • Optimize Your Exposures
  • Master the Triangle
  • Slower Shutter Speed
  • Learn to Pan
  • Use Intentional Camera Movement
  • Use Wide Lenses to Create a Sense of Inclusion
  • Learn to Isolate
  • Use Tighter Apertures to Deepen Focus
  • Use Bokeh to Abstract
  • Consider Your Colour Palette
  • Lines: Use Diagonals to Create Energy
  • Lines: Patterns, Lead my Eye, Horizons
  • See the Direction of Light
  • Light: Front Light, Side Light, and Back Light
  • Quality of Light: Further Consideration
  • White Balance for Mood
  • Light: Reflections, Shadow, Silhouettes, Lens Flare
  • People
  • Experiment with Balance and Tension
  • Use Your Negative Space
  • Juxtapositions: Find Conceptual Contrasts
  • Orientation of Frame
  • Choose Your Aspect Ratio
  • Use Scale
  • Simplify
  • Shoot from the Heart
  • Listen to Other Voices (Very Carefully)

And there is plenty more content to complement and extends these ideas. What’s not shown in a list is the excellent and sage advice throughout the book. I will let David duChemin have the last word…

Pace your-self. Anyone can master a camera; that just comes with time. It’s the other stuff — learning to think like a photographer — that takes so much work and allows this craft to become the means by which you create art.
The Visual Tool Box by David duChemin

And it is thinking like a photographer that you will quickly learn from reading this book.

How to buy this great book

This book was originally published as an ebook. However, it is no longer available in that form. The book has moved into the real world. It will be available on Amazon as a Paperback From 31 Mar 2015.
The Visual Toolbox: 60 Lessons for Stronger Photographs (Voices That Matter)You can per-order the book from Amazon.

The power of light and shadow

Facial shadows

• Facial shadows •
Image taken from the video.

Great portraits rely on shadows

Shadows define a portrait. So it is no surprise that good lighting to get the shadows right is a wonderful idea. But what most people don’t realise is that, almost every time, more lights make things more complicated. One light is almost all you will ever need to get a face right. The rest can be done with a reflector.

Shadow work

In the video Mark Wallace shows us how the face can be properly illuminated, how to do it and more important how to make it look beautiful. He looks at ugly shadows and hard light and explains how to remove them and subdue them using soft light. In all, this is one of the best best portrait lighting tutorials I have seen on video. Enjoy it. There is some really useful stuff presented in a simple and understandable way.

Action portraits… easy to do

Action Portraits

• Action Portraits •
Getting the shot in action situations is not difficult although the lighting can prove a key aspect of success. (Shot taken from the video)

Getting it right…

Most photographers have a go at action shots. Vehicles are common targets – they are easy to find and fun to do. Action portraits can be great fun too and you can do them at home.

Lets talk flash…

 Set up pictures at home to show some action.

Easy action shots at home for anyone.
“Some more bed-jump!!” by Mr Din, on Flickr  External link - opens new tab/page

In its most basic form, it’s a portrait of someone in motion (action?). The wonderfully muscled fighter in the shot above is one way to go. On the other hand pictures of your grand children jumping into the air can be just as effective – and probably more relevant for many of us!

Use off-camera flash for best results

The basic technique is to capture the action with a flash. You can use the on-board flash on your camera. However, it will tend to leave tight shadows on the wall behind the action because the flash is directly in line with the optical axis of the camera. Such shadows look artificial and are difficult to remove in post processing. They look as if there is a slight double image. In the picture of the jumping children the flash is from the left hand side. If you look carefully the shadows are projected away from the kids giving a more realistic feel.

Off-camera flash can be placed to the side of the shot and used to illuminate the scene, give it a little depth and off-set those harsh shadows. For this you can use an off-camera flash. I use this one…

YONGNUO YN460 Flash Speedlite for Canon Nikon Pentax Olympus…  External link - opens new tab/page
This is an excellent buy… it is inexpensive and can be used for any off-camera flash situations. It is reliable, robust, flexible and effective.

I have several of these flash units. At about one fifth of the price of a branded product they are excellent value. If you want to get something a little more sophisticated you can get the YONGNUO YN-560 II Flash unit  External link - opens new tab/page – also a great product. With inexpensive remote flash triggers  External link - opens new tab/page you can set them off when not connected to the camera.

What are you going to capture?

Plan out your scene in advance. You will need someone to be the action taker. You could use more than one person. Then, work out what they are going to do. Jumping on the spot is a favourite. You also try jumping or stepping off something like a chair or low table. You can do skipping, walking, Kung Fu, Juggling, tumbling, hula-hoop, playing ball… well all sorts of things.

How do you do it?

I am assuming that you will be working in a domestic room with a white wall behind the actions.

It is best to use a robust tripod to mount your camera. This is essential. Action shots often cause floor movement and you want a good tripod (Manfrotto 055XPROB)  External link - opens new tab/page and tripod head (Manfrotto 322RC2 Grip Ball Head)  External link - opens new tab/page to give you a chance.

You will need to pre-focus your shot and have it ready to take because you cannot easily compose for action in progress. So set up the camera in advance. Here are some typical settings to get you started…

  • Turn off image stabilisation on your lens.
  • Focus your lens on your subject then turn off the auto-focus.
  • Set white balance to the appropriate ambient light setting.
  • Set ISO to 200 (or 400 experiment).
  • Aperture priority (select F5.6 as a start) [Shutter speed will be set by the camera].
  • Flash synchronisation – 200ths or 250ths of a second (if you need to set it check your manual).
  • Flash setting, try the lowest setting or 1/16th or 1/8th power – again, experiment.

This will give you appropriate starting points. Check you shot and then make any changes to the settings. If you click up or down a setting – say aperture or ISO – then the camera will compensate with a different shutter setting for you. Experimentation is good!

OK, now you are ready for action… this part takes a little practice. The idea is to sit next to your camera ready to push the shutter button as soon as the action is where you want it. As you have already lined up your focus the person can now perform and you can press the button as you see fit to capture your shots. Fire away, enjoy yourself.

Two tricks you have learned here

1. The pre-set-up of your shot is important. There are lots of situations where you can do that. So think about it – that is one of the benefits of having a tripod.
2. Flash! The way to capture a good shot like this is to have a very fast shutter speed. That freezes the action. However, I have suggested you hand the shutter speed to the camera by using the “aperture priority” mode. Well, you can in fact control shutter speed another way. By varying the flash duration. “What?”… I hear your cry. “You did not tell us about that control! But I did. Flash intensity is always the same for any given micro-second. It becomes more intense for the sensor if you leave it on longer. When you set the power of the flash to low power you are actually shortening the length of the flash. Hence you are more able to freeze the action. However, to do this you will need to have your ambient light lower. So using natural light rather than bright room lights works better for this technique.

See how its done in a video

In the video you can see all this action in a full process. The photographer, Joel Grimes, starts off by some discussion about how he came to discover this secret and how he used it in a studio context. Then from about six minutes into the video he shows you how to take the shots.

Remember that the settings are important. He mentions about low power and says that it works to freeze the action IF the flash is more intense than the ambient light. Watch out for that.

One other thing worth looking at is the shot progression. He is constantly assuring his model that he has done a good job. Then he is at the same time developing his shot. He is constantly evolving the positions and situations until he gets the shot he wants. This is critical. Make sure you look out for odd lighting effects, hands over face, bits of body out of the frame etc… He works the shot to reach his ideal as he visualised it – then stops. Even great photographers have to practice and perfect a shot. This is quite a helpful lesson about that. Enjoy!

Review your own photographs

Low flying aircraft

Click image to view large
• Low flying aircraft • By Netkonnexion on Flickr External link - opens new tab/page
Every picture has its merits. However is there enough in the picture to interest and invigorate the attention of your viewers? Sometimes, like this picture, if you don’t have a point worth making then you should not really bother with it.

A picture is a wonderful communication.

But like speech if there’s no point there is no impact. To help you see if you have made a great picture here are some guiding points.

We are going to consider…
• What you are communicating:
• Presentation:
• Camera technique:
• Technical Quality:
• Visual Awareness, Visualisation, Seeing and aesthetics:

Looking critically at your own picture

When you make a picture your previsualisation of what you want to achieve is critical to the outcome. If you don’t know what you are trying to make how can you make it convincing? So try to have a mental image of what your picture it going to look like when you make it. If you can see the image before you make it you should have a good point in mind – a reason for making it. All too often snappers see something and just ‘snap’. That being the case, few of the images will have real meaning or impact.

When looking at your own picture you must see if there is really something there. Are you really saying anything? Are you really communicating with the viewer of your picture? Or, is what you have just made only a simple picture? To have real impact is to create in the viewers mind an image. An image that means something to them. So look at your picture and honestly ask yourself what is the viewer going to get from it? What will it mean to them? If you find that you have really said something in the picture then the first criteria for success has been passed.

To this end you should consider how successfully each of these things has contributed to the success of the image…

  • Personal input: have you understood and connected with the subject
  • Appropriate communication the message, mood, ideas, and information you want to pass to your viewer
  • Complementary use of the photographic media (mounting, projection, printing, texture of print etc.)
  • Appropriate imagination and creativity / suitable timing for the shot
What about the other things?

• Presentation: It is important to have a good presentation for your picture. Have you edited out distractions and sensor/lens spots, removed the errant sweet rapper littering the foreground etc. In other words, have you done the little tidying up tasks that make the image stand up as clean representation of your original vision for it? If it is a print, is it well mounted in a non-distracting way. Is the printing immaculate or are there streaks and spots; over-run and smear.

• Camera technique: Is the sharpness the way you want it – deliberate softness is fine as long as that is making an artistic point in a way you intended. Is the depth of field right for the composition? Have you emphasised the point or simply missed the point. Is the digital noise too high, or the contrast too low. What you are looking for here is to see if your prowess with the camera has come through. Did your technique work or were there any errors or mistakes that detract from the delivery of your point? Some of the other things to consider are…

  • Viewpoint to the subject – exciting, interesting, different, right?
  • Choice of lighting – does it complement or complete the subject or is it at odds with your point?
  • Accurate focusing – accurate choice of focus for the subject.
  • Appropriate quality and choice of exposure.
  • Suitable use of depth of field (aperture).
  • Appropriate shutter speed for the subject (and shot timing).
  • Highlights and shadows (ensuring detail is retained)
  • Appropriate quality and choice of exposure – does the balance of light and dark complement or detract from the subject?
  • Is the quality of the light effective or bland; does is make a statement or is it of little consequence?

• Technical Quality:
In this category you should consider exposure, colour and tonal control…

  • Absence of processing faults (dust, spots, hairs, processing artefacts, image damage by sharpening etc.)
  • Appropriate adjustments of colour temperature; hue, saturation, colour balance etc.
  • Appropriate tonal use and control of the range of tones.
  • Good image finishing: removal of distractions, removal of abrupt or discordant features.
  • Appropriate use of levels, curves, colour management, filters, overlays etc (post processing)

In this category you are looking to make sure that the image is digitally developed properly. Is the exposure even or has it been obviously enhanced and changed. Is the light effective to make the point or has the exposure not been fine tuned. It is easy to take a picture, but all these thing go into making an image. Think about what you are trying to achieve and does this picture achieve it with its colour and technical delivery/

• Visual Awareness, Visualisation, Seeing and aesthetics:
Do you think that your shot, the one you have in front of you sees anything different? Are you reporting what you saw or expressing a point, message, communication, feeling… does this picture have IMPACT?

  • Is the composition, design and cropping of the image an effective aesthetic construction?
  • Appropriate simplification (minimising complexity and clutter)
  • Distractions / intrusions should not divert the viewers eye
  • Good use of light, mood, texture and colour
  • Good use of masking/manipulation where appropriate
What you are doing…

Each time you want others to look at your picture you want to impress them, to lift them, to… well, get out your message or point for the picture. The type of questions I have asked above are aimed at getting you looking at your images with a critical eye. If you are honest, you will find that none of your pictures will be satisfactory in all of the above. But if you find you are gradually improving your standard of delivery you will see that the above get closer to ideal with every new picture. Critically reviewing each picture before you publish print or show it to other people helps make sure you are producing something worth showing.

You won’t be right every time. But you will see as you develop, your comments will begin matching those of other people. You will than have a benchmark that tells you if your work is measuring up to peoples view of it. Or, more importantly to see if your picture is measuring up to your original vision of how you wanted the shot.
