Ray Tracing Matrix, Linear Matrix Transformation relation at Elmar 5cms ?

[Mustafa Umut Sarac]

20 years ago , I had a Leica IIIC with 5cms Elmar from 1946. I took selfies from a mirror in a few candles light and I have just impressed with my pointing fingers been bent somehow.

I researched that for 20 years and could not find an explanation. When I was reading scientific articles , I found that ray tracing was done by matrix calculation. Than I found linear matrix transformation and its like a photoshop trick , you can narrow the head of mona lisa or bent to one side , other side to other angle.

I want to ask , what do you think. I know one small piece of information like 3d optical transfer function but what do you think , how should these come together ?

Scan, Photoshop. Math made easy. Hidden, really.

I'm honored that you put me on your ignore list. If you take me off your ignore list you'll be able to read this explanation.

The ignore function hides posts by posters on your ignore list from you.

I haven't put you on my ignore list. I can see your posts, you can't see mine. Your decision.

Umm... if you are on his ignore list, he probably can't see what you just explained.

Of course. His problem, not mine.

Isn't it wonderful that ignore really means ignore?

Maybe this should be moved to the "Ethics and Philosophy" sub-forum and re-titled "Existentialism"?

Hmm, I see at least one post has disappeared without even a place-marker.
