In a workshop held by nature photographer John Shaw, that I attended in Orlando, Central Florida a few years ago, I saw a group of prints that he had for sale. Interesting enough he explained to those present that among those prints there were prints made from digital files and prints made from film. Can you tell which one was made from film and which one from digital? I did not open my mouth but I could recognize one of the prints he made from a Nikon F3 simply because I have seen it in one of his books. NOBODY there could tell which one was from film and which one from digital files.

There is a formula for determining what focal length lens was used but, you need to know 3 items to determine the 4th. You need to know the image size, how big the original object was, & how far away you were from the subject. The formula is I/F:G/A. I = image size; F = focal length; G = size of the original object; A = the distance from the subject. If more than 1 of the items can't be determined, you'd have to guesstimate. It goes back to aerial photography when you were taught to determine how big an object on film was based on knowing the focal length of the lens used, the altitude of the plane, and the image size on film.

Is there a way to determine what lens was used when viewing photos taken with a film camera? I'm thinking probably not, but I have to ask. lol. I recently bought the following at a garage sale:

Minolta Maxxum 7000
Sigma 28-70 lens
Minolta 50mm lens
Minolta 70-210 lens
Various filters and a filter holder

They only wanted $30 for everything! But had no idea if the camera worked. So I figured for 30 bucks, it's not a big deal if there was a problem with any of the items. So I cleaned it up...no scratches on the lenses since they were covered with protective filters. My daughter had old film from a photography class...it was expired but I just wanted to see if the camera worked. I shot the roll of film using all the lenses to test them out. Just got the photos uploaded today from The Darkroom. Looks like the camera and lenses work great! But I just don't remember what photos I took with what lens. It doesn't really matter...I really just wanted to make sure it all worked (it does...and the expired film, too...). But I was just wondering if there is any way to tell what lens was used for each shot.

Thanks for helping me out. I haven't shot film for a long time and back when I did, I probably didn't care what lens I used, so never thought about it. But now that I'm learning more about photography, the more questions I have! :)
