I must teach someone how a dSLR works at work. So YouTube, Vimeo and, generally, videos are banned.

My 'apprentice' is smart, however I feel that he needs an animation with a 'transparent' (CGI) dSLR showing how the aperture's blades are closing, the mirror is lifted, (optionally) the curtains are open, and the sensor is exposed for a certain amount of time. I need to show him what means 'aperture' and 'shutter speed' in a visual way. I searched for exposure basics on internet and found different diagrams and articles but I'm looking now for something visual.

Where can I find an animation for this?

  • Why on Earth are videos not allowed? They seem an ideal way to teach this. – Philip Kendall Sep 27 '15 at 10:36
  • Something 'visual' but no video... Does your apprentice has a serious photosensitivity problem or a maybe a form of epilepsy ? What kind of animation are you looking for ? Limitation on frame rate ? – Olivier Sep 27 '15 at 19:08

    I expect that videos per se are not banned, but that these popular video sharing sites are blocked as a matter of policy at John's workpace. – mattdm Sep 27 '15 at 20:23
  • @mattdm is correct. We have a firewall which blocks these sites and file extensions like .mp4 .avi etc. The reason is obvious: To spend the entire working time watching videos. – John Thomas Sep 28 '15 at 6:45
  • To teach him outside of work? – JDługosz Sep 28 '15 at 22:38

This webpage:

http://digital-photography-school.com/photography-1016-shutter/

Has some animations on how the shutter curtains in a dSLR work to control the shutter speed, but nothing on the mirror.

  • should have started with DPS, I use that site all the time. – thebtm Sep 28 '15 at 17:53

I think I found something which shows quite clearly whats happening at:

It is good because it has a step by step mode, different lighting conditions and, also, it shows the resulting photo.
