I did this last year for a coin dealer repaid me for my purchases, plus a fee for my time. I bought a vertical copy stand on line, after reading an article on "coin photography" which provided data .
The stand cost about $120, holds any 35 mm ( aps, dslr, etc.) above the flat plane, camera can move up or down. I used a Nikon #2 52mm close up lens, and a 55-200 aps lens on an old D200 ( they paid for it)with cheap lighting. I photographed many coins, either single coins or a full 8 /12 x 11 page of coins all clear enough for the dealer to advertise the coins. Byh moving the camera up/down and adjusting the zoom lens ( f 16) it worked out well.
Exposure was automatic using f in camera meter. I do not recall who I bought the copy stand from, and bought the used lens at a local camera store.

I bought anEpson st-4000, printer,scanner,copier, primarily because it uses tanks of ink. The saving in ink has been hugh, the thing was kinda expensive, but it turned out to be the best thing since sliced bread...

I've done some document photography on archival materials. I found the simplest way to do it is to use the longest lens you have, your 140, and back off about 6 feet and use the built-in flash for your light. The flash is bright enough that you can shoot at F-22. That was important for me because some of my materials were bound and I needed to get a little bit of depth of field to bring everything into focus. A tripod is a big help if you can manage one. If your 140 mm lens does not let you zoom in enough maybe you can borrow a longer lens to use.

Thank you. I have a 56-300mm f/45-5.6 tele-zoom, but didn't think about using it. However, my working assumption is that I would be able to handle the documents, thus having close proximity to them. But it might be handy to keep my distance and let the lens (and lighting) do the work.

Thanks, everyone, for your replies.

I have offered to assist in a legal research project, photographing documents (envelopes). The only requirement that I am aware of is that the address is legible.
I have several lenses for my Nikon D7500. My all-around go-to lens is a 18-140mm 3.5-5.6 zoom, and my brief tests suggest I can get a legible image from about six inches away from the subject. I also have a 35mm 1.8 prime lens and an 18-55mm 3.5-5.6 zoom.

What I don't know is what the lighting will be like. I'm inclined to use the prime lens, as it's faster in low-light situations. But the 18-55mm should provide more flexibility if I'm not able to get close enough to the subject.

Has anyone done work like this before? I should also note that it's unlikely I can set up a tripod, flash and other gear, so my offer is to give a step up from using a phone camera.

Hints? Ideas?

Yes, I've photographed documents before. I like taking them on the back deck in the shade for nice even lighting. A macro lens would be your best choice since the nature of a macro lens is to have better edge to edge sharpness than other lenses. For the lenses you have, you should just do some experimentation. Since you are working with a 2 dimensional subject you do not need to stop down to f16 or f22. Usually the sharpest focus of a lens is somewhere in the middle range. In olden days a rule of thumb was the sharpest a lens was, was 2 stops down from wide open. That would mean a 2.8 lens would be sharpest at f5.6. With the newer computer designed lenses that is no longer true. With that 2.8 lens, you could use 5.6, 8, or 11 and have excellent sharpness. If you have to copy inside, two lights, either hot lights or flash should be placed on opposite sides of the document to even out the light. Otherwise using only one light will make one side of the document brighter than the other.

I use either my iPhone or iPad and use adobe document scanner. Free app if you have an adobe account. Take a picture using the app and click OK the app creates a PDF of the document. You can check that the edges are good and trim if necessary. You can also adjust color. Docs are then saved to adobe documents folder. you can share and email them as you see fit. Just a thought.

Well, the deed is done! I used my 18-55mm with available lighting. There were nearly 2,000 documents to photograph, and while I brought a tripod (a Peak Designs Travel Tripod), I would have done better with my Velbon VS-3, as the Peak doesn't have a way to position the camera overhead, and the Velbon does. Lesson learned. I wound up leaning over to take the shots, and now my back is complaining a bit!

I had a helper to feed the documents, so all I had to do was use my back button focus and snap the shutter.

As I said (I think), I wasn't trying for art, I was trying for legibility. In that regard, mission accomplished. This was a volunteer job, not a paid assignment, so I obviously didn't spend the same amount of prep time I would normally.

Thanks, everyone.

I'm in my 48th year of owning and operating a solely owned publishing and bookbinding business. A major part of the business required my learning and applying ever changing photographic principles to achieve the highest degree of quality in all of the many products we produce.
I'm still learning, and if I can help anyone, photographically speaking, with some of the things I've learned over the years....(first camera - 1949,. U.S. Navy Photo-Facsimile Technician [sending and receiving classified wire photos and documents] .1955-1959, began publishing - 1970, started the bindery and small press business - 1972 to today.
One of the projects I'm currently working on is a Macro-photo comparison study of crystals and gemstones (requires very difficult lighting) modern coins (requires proper lighting, strict macro processing,
(minimum requirements necessary for publishing) and lastly.... patience...Most of my work is shot with a Nikon P600 -16MP cmos, proof shots are with an LG Stylo-3, and an LG LM2, both 13MP ok for proof shots and 'bracketing'. BE AWARE - LG is closing it's Mobile phone business, and support may be very limited or non-existed.
More shortly
