Hi everybody and glad to be here and seeing all of you.
I am a physics graduated person with no experience in experiments related to lens and photography and I have a question about a relatively simple lens design but due to lack of time I have not been able to do extensive research on this issue and am badly confused.
My question is that I have a lens at hand(3 lens system with two plano-convex and one concave lens in between) that projects film on screen(wall) located nearly 2 m away from it and I want to modify it and make the project as close as half meter with enough magnification.
What should I do and where should I go to get required knowledge?
I have read the ultimate guide for classic lens design and am not confident if it suffice.
Any thought or hint will be greatly appreciated.
Thanks in advance
