I agree Casey, in terms of optics it is the most fascinating. Best Regards Edward [nt]

Using the "Zeiss formula" to understand the circle of confusion
How I learned to live with the technical details of photography and still keep my sense of humor - or not. We all have our own circles of confusion, but today we take a brief look at the CoC as it pertains to taking pictures. You are about to enter anothe...
Now I'm really confused.
But I suppose it's understandable since it's in your title. Will re-read later to try and make better sense of it. Thanks for sharing! Fernando
LOL... nothing more than basic optics ; )
and I was worried that Louis Derr's equation (4) would raise all kinds of questions... and I spent about two hours tracking down the meaning - silly me. The math is easier to understand than Derr's written definition of hyperfocal distance. I guess one ke...
I looked at one of these online calculators for Sony RX 100....
and It looks like the bigger the f number and the more lighting you have the shorter the focal length, for best macro photo of your watch, and relatively even depth of field. Thank you for sharing Casey it is very helpful . Best Regards Edward
terminology can be a little tricky... for a given kit
The smaller the aperture opening (e.g. f/22) the larger the DOF The shorter the focal length (e.g. 15mm) the larger the DOF There are other considerations... as the aperture opening is set smaller the resulting exposure time becomes longer. I usually don'...
