Photo Forum / General Photo Topics / General Topics / April 2008copying very old black and white photographs
I need to copy some very old black and white portrait photographs. They can't be scanned because they are mounted in glass frames and are very fragile. They are borrowed and I cannot take them out of their enclosure. I must make do with them under glass. I have a Nikon Coolpix 950 that I don't think will help me here. Please let me know if it can. My other camera is a Canon AT-1 that I haven't used in over 20 years. I have a set of macro lenses for it, and remember copying photographs with it. I used some special b&w slow speed film as I recall, and a tripod, lighting, and aperture shutter speed guesses or tests. Helpful suggestions on how to best copy these pictures is welcome. e.g. what film, aperture, shutter speed should I begin with? Or, assuming I'm going to need to do this more in the future (I have begun some serous genealogy), should I bite the bullet and buy a digital SLR? If that route, what is an economical digital SLR? I suppose that if I bought a Canon digital SLR, I could use the handful of AT-1 lenses I have? Thanks in advance for advice!

Scanning is a good idea -- but a lot depends on the depth of field of the scanner's lens. This can vary quite a bit between brands. If you do decide to use film in your AT-1, use a fine grain low-speed film such as Kodak TMax 100 or Fuji Neopan 100. Unfortunately Kodak discontinued Technical Pan years ago. When shot at ISO 25 it was almost completely grainless. If you don't have access to a copy stand, mount the pictures on the wall and use very diffuse light from both sides at about 45 degrees. You may still need a polarizing filter to get rid of all reflections in the glass. You should be able to use a polarizer with your Coolpix; it may take some creative use of gaffer's tape. An old trick is to take a large piece of black matte board, cut a hole in the center the diameter of your lens, and mount it so that only the very end of your lens pokes through. This will get rid of most 90 degree reflections -- such as you and your camera! As far as exposure goes, use an incident meter and then compensate if what you are copying is either very light or very dark. Good luck! --k >I need to copy some very old black and white portrait > photographs.

Lighting the pictures under glass will be difficult, but not impossible. Use two or more lights at 45 degree angles to the picture. A more shallow angle may be easier. Frankly, I would use a film camera for this project, as the negatives will be easier to store and more robust over the years. If you shoot with digital and burn to CD/DVD, you will have to re-copy every couple years to provide for any deterioration of the disk and to convert to whatever storage medium becomes popular in the future. Your negatives, on the other hand, can always be viewed by holding them up to the light, and printed either optically or scanned. As for using your AT-1 lenses (Canon FD mount) with a Canon digital SLR, sorry, no. You will need an adapter, which has a 'helper' lens in it to provide infinity focus. This helper lens may or may not be of equal quality to your Canon lenses. Thanks all for the sage advice! I looked up the Nikon Coolpix 950 manual. When I got it I didn't need the advanced features, so I forgot it actually has a macro ability. In the interest of time and money budgets, I'll be exploring that to copy the old pictures, at least at first. Since the photographs are not in excellent condition to start with, this approach may be adequate. The lighting tips were particularly helpful, and the note about needing a lens adapter should I ever get a Canon SLR for the AT-1 lenses. This kind of removes any Canon constraint when I do choose a digital SLR vendor. Thanks, John > Thanks all for the sage advice! > [quoted text clipped - 7 lines] > > The lighting tips were particularly helpful, One thing you might try in order to avoid reflections of your camera in the center is to shoot from a bit of an angle then do perspective correction on the computer to square it up. Of course you'll lose resolution on one side but as you say there may not be that much detail anyways. > and the > note about needing a lens adapter should I ever get a [quoted text clipped - 3 lines] > > Thanks, John How come the polarizing lens doesn't take care of all of the glare? Thanks, newbie. > How come the polarizing lens doesn't take care > of all of the glare? Thanks, newbie. The polarixing lens only get rid of the glare that is pokarized at right angles to the lens. >> How come the polarizing lens doesn't take care >> of all of the glare?

Thanks : -) I have taken pictures of old pictures with pretty good success, as long as you're not looking for technical perfection, assuming you want them for something like a Family Tree Maker album or something similar. If photography interests you at all, you'll never be sorry for buying a DSLR. I have Nikons and am totally satisfied, but I doubt that any of the popular brands would disappoint you. I just saw a D40 with a kit lens for under $500 and they all have entry level DSLR's in this price range now. The Canon web site should provide you a lens compatibility chart, but you won't use them much if they're not autofocus once you try the kit lens. >I need to copy some very old black and white portrait > photographs.
