Ten great tips for photographing landscapes

Landscapes appear inherently attractive to the eye.

We all love taking landscape shots at some time or another. However, they are also quite a challenge. There are a few simple things that you can do to get a great landscape shot.

Use a tripod!

The most important landscape photography technique is to use a tripod. For your shot to be successful you need to get the sharpest and most carefully framed shot.

  • Framing: When you put up your tripod you give yourself the best opportunity to get the framing right because you can take your time. Look around the shot. check the edge of your frame. Make sure you have all the right composition elements and have a meaningful subject in your viewfinder.

  • Stability: The tripod will give you the most stable platform for your shot. Most photographers miss this essential when starting out. Sharpness makes or breaks a landscape shot. Starter landscapers often think a hand held stance is good enough. It may be possible – sometimes. The chances are reduced. If you want to get right into the shot you must get pin sharpness.

Vibration elimination

Beating the movement blur of the hand-held shot needs more than just a tripod. Your tripod technique is critical too. The most important part of using a tripod is to reduce the vibrations through it. Here are my ten tips for making your tripod-based landscape shot pin sharp.

  • Tip 1: Keep the legs as short as possible and don’t use the middle elevating column. The short legs and no-column policy keeps the tripod tight and that reduces any integral vibration in the tripod itself. The vibration is reduced because the tripod is stiffer overall if the legs are retracted. If you must elevate it, make sure you extend the thinner, vibration prone, bottom of the tripod legs last.
  • Tip 2: Use a cable release: Pushing the release button (shutter button) moves the camera and creates vibration in the tripod. A cable release of some type will set the camera off without your heavy finger involved.
  • Tip 3: Use mirror lock-up: Most DSLRs will have a menu setting that will lift the reflex mirror before the shot is fired. The number one source of vibration in a camera is that mirror twanging up and down! The mirror lock-up function will remove this vibration. Check the manual to see how it is done on your camera.
  • Tip 4: Turn off auto-focus: The engine and the act of the camera tuning its focus causes vibrations in the tripod. These set up a resonance up and down the legs – the vibration affects your shot. You will produce a much more accurate focus by hand anyway.
  • Tip 5: Turn off image-stabilisation: If you are on a tripod you don’t need it. However, the slightest breeze or vibration through the ground will set it off. The motor attempting to compensate for tiny vibrations in the tripod will in fact create more vibrations. All image stabilisation systems are designed to iron out natural hand movement. Vibration in a tripod creates its own peculiar vibration which just aggravates the stabilisation system.
  • Tip 6: Hang a weight on the tripod hook under the centre column: This weight adds tension to the legs and forces greater stability to the tripod. One more way to reduce movement.
  • Tip 7: Stay away from vibration sources: Its not always possible, but roads, railways, fairgrounds, airports, ferry terminals and ports as well as the obvious wind all create ground vibrations. Less obvious are underground trains and tunnels under your feet, tall buildings swaying in high wind, bridges vibrating from feet and vehicles… well it’s a long list. Think carefully. You may find you have put your tripod right in the centre of a major vibration source.
  • Tip 8:Remove your camera strap: or as a secondary measure peg the strap tightly to the tripod. If you let it hang loose it will catch the wind. That will move or vibrate the camera.
  • Tip 9: Longer exposures: The camera shutter is also a significant source of vibration. Nevertheless, it has to open. Using a longer exposure is better because the shutter is open completely with no movement for at least part of the shot. This reduces the impact of shutter shake. The shutter release and movement still creates a vibration profile. By design, it has been carefully calculated to reduce the impact of the shutter movement – but it does not reduce shutter vibration completely. So, longer exposures help reduce the vibration just a little more.
  • Tip 10: Use a wind-shield: Even a light wind will induce vibration in a tripod. So, shelter it from the wind. Hold your coat in front of the tripod (not touching it) to shield the wind. Better still, if you are going to be there for a while, put up a staked-out wind-shield to divert the wind properly. Alternatively, take the shot from cover of some sort.

Remember, these measures all add up. Sharpness in your shot is the result of working at all of these. Put all of the above in place and you will get a really sharp shot.

Important File formats – JPG

Quick and easy – not very flexible

Digital images come in a range of standard file types which computers, cameras, mobiles and scanners are able to understand. However, they are not able to interpret all image file types. Only those they are programmed to use. It is important that you know about the file types you use because they can seriously affect your photography. I am going to introduce you to .jpg files. They are the most common file types used in digital cameras.

Which file type you have is labeled by the file extension. That is the three characters after the last dot in the file name. If you cannot see this file extension refer to your computer help files to find out how to display extensions.

A file with a .jpg extension, for example ‘myimage.jpg’, is what we call a JPEG file (pronounced – ‘j’- peg). That stands for the “Joint Photographic Experts Group” who formulated the .jpg image standard published in 1992. In digital terms that is a long time ago. However, the JPEG standard has been highly successful and has proved robust. It is not perfect, neither does it do everything.

First and most importantly .jpg files are what is called a ‘lossy compression‘ format. Media files contain a lot of data – very large quantities in fact. Most of that data is used to create colour variations and tones that are very subtle. In a photograph a lot of tones and hues are not noticed by the eye. To save storage space and speed things up your camera dumps a lot of that unseen data when it creates .jpg files. That’s fine as long as the lost data is stuff the eye cannot see in the photograph. The benefit is that the lost data makes files smaller, as well as quicker and easier to move, send and store.

There is a down-side to .jpg files. Every time you open, edit and save a .jpg file it goes through the compression routine – dumping more data. For files you are going to edit on a regular basis this is bad news. Each save will lose some of the data that creates the image. As a consequence the quality of the image will be damaged over a series of edits.

Lossy compression in .jpg files damages the file each edit/save cycle

Lossy compression in .jpg files progressively damages the file each edit/save cycle. Eventually, the loss of data becomes visible. The image is a composite of four versions showing increasing compression left-to-right. Left hand side – the image shows low compression with 60% of the original data still in the file. Right hand side – only 2% of the original data is left. Over-compression, various edits and resizing all have an effect on final quality of the image.

As you can see from the images the damage ruins the picture. However, a low compression is a good optimum. The file is smaller and still of acceptable quality. The small size allows easy use for things like posting on the Internet.

There are other implications of a lossy format. The lost data seriously reduces your options for editing the image. Other file formats keep that data. Most notably these are the ‘RAW’ formats from your camera manufacturer. RAW files are created by the camera directly from each of the sensor points in the digital image sensor in your camera. A RAW file stores all the data. In doing so, the file is preserving the data for you to make significant changes to the image later. These changes are often not possible with a .jpg file. While some small colour changes, brightness and other aspects of the file can be changed in a .jpg file, the degree of change is limited. When editing a RAW file you have a considerable amount of potential to recover over exposure, underexposure, colour casts, hues, tones and other attributes of your photograph.

The JPEG standard has produced a robust file standard that is widely used. The compressed size means a lot of data is dumped. This reduces the editing flexibility for the photographer. On the other hand the file is small and easy to store. It produces a good image as long as it is not over-compressed. However, to guard against loss of quality always retain an original copy of your file. Only edit your file copies so that you can go back to the original .jpg file if things go wrong.
