I have been wondering about the "WHY's" for the past few months that I've studied photography on my own ( I am a newbie), and no one has explained it as well as you have. Maybe it is not the best for someone who just got a camera and is looking for a quick formula (which doesn't exist!) ; but it is PERFECT for those of us who learn this way and want to have a clear picture of what a camera is and does before attempting to take pictures in a skillful manner.

The image plane is 6.3mm (H) and 5.4mm(V). Due to constraints, I can place the lens at maximum the focal distance of 16mm. The object I want fitted into that image plane is approximately 35mm x 15mm or a bit larger. Is it possible to get a sharp image of this object? Its not a pinhole camera..the lens has an extra angle of 19 deg. Thanks for any help offered Hi,

I agree with the benefits of discussing theory and physics. I've been reading lots of information about how to understand all of this stuff and your lessons are the first that I can actually grasp, understand how photographs are created and therefore am retaining the knowledge so I can use it in the field. I'm reading through all of the lessons now and plan on trying some of the homework assignments. Thanks! These lessons are great! I agree with the benefits of discussing theory and physics.

I teach 11 year olds and have already used the pinhole camera to explain light paths, I now want to set up your magnifying glass experiment. I have been into photography for a year now and understand a lot more than I did at the beginning - your tutorials are strenthening my foundations and giving me the will to improve. Thank you.

If one was on the first 101 tutorial, one wouldn't even know there was another part. There are no links between 101 and 101.2, nor is there a listing on the 101 page. Just a recommendation... but thanks for the great work. We all appreciate it, I'm sure.
