Electrical tape fixes the problem
Hands up if you have used sticky tape to fix something… yup, I guess most people have. Now top camera manufacturer, Canon, have too.
Earlier this year the new Canon 5D mkIII ran into trouble when a light leak became apparent behind an LED display. According to Lensrentals.com the tape fix is light-tight. Roger Cicala says in his latest posting, “Some people seem to think tape is a bad or cheap fix. It’s Not.” He goes on to say that this tape is extremely durable and the fix… “works flawlessly”. It “seems silly, but it’s logical and effective”.
The problem does not undermine the testing process at Canon. It is not possible to test every scenario or new developments would never make it to the consumer at a reasonable price. We now know how unlikely the problem scenario is to arise. Canon have dealt with the issue confidently and quickly and are shipping with a simple fix. This sort of issue arises frequently in hi-technology first releases. There appears to be little reason to lose confidence in Canon. If your camera is affected Canon will fix the problem for you.
The light leak in the new Canon 5D mkII caused upset, production delays and delayed shipping. After investigation Canon issued a notice to assure users and offered to fix the problem free of charge. Independent scrutiny has confirmed Canons examination of the problem. The light leak skews the results of the automatic light meter readings. However, this only happens in extreme low-light/dark conditions. The use of auto-metering in extreme low-light is an unlikely scenario. Canon say that there is insignificant effect on exposure.

Todays Google Doodle honors Eadweard J. Muybridge is celebrated for his pioneering photography using stop-frames.
The Google Doodle today is an animation of a famous study of horses in motion. The photographer, Eadweard J. Muybridge, is best known for this work. Muybridge was engaged by race horse owner and breeder Leland Stanford. Artists had depicted horses running with all four legs off the ground. Stamford, a californian business man and horse breeder, wanted proof of this locomotion. Muybridge deployed 24 cameras to take detailed film sequences capturing the motion of horses legs throughout the galloping cycle. He produced a film strip that showed the whole range of leg positions.
Muybridge did his work for Stamford in 1872. The sequence he produced proved that all four legs did indeed leave the ground at once. Artists had depicted the legs streched out to the front and behind when this happened. Muybridge showed that the legs were all tucked up under the body at the time they were all off the ground. The position is shown in the Google screen capture above in the first column.
Muybridge was born in Kingston on Thames, UK, on 9th April 1830. He later lived in the United States. While recouperating from a serious stage coach accident he became a committed photographer. He initially focused on landscapes establishing his career as a photographer. After his success with the horse film sequences he continued to investigate human and animal movement. His work was associated with academic papers and popular books. He died of a heart attack in 1904.
His work on the film sequences is widely regarded as a precursor to modern videography. Muybridge invented the zoopraxiscope during the course of his work on movement. The moving-sequence invention was one of the earliest attempts to animate film into moving pictures. His early popular insights into movement in film are said to have contributed to the later developments leading to motion pictures and eventually cinema.
The modern DSLR owes a lot to its predecessor the SLR. It is really much the same beast! Instead of film to record an image it uses a complex on-board computer. However, the most interesting thing about the modern DSLR is its optical path and the simplicity of a mechanism that has been with us since 1949…
