Tips on shooting a coin?

[John Kasaian]

I'm working on an article about coins which requires some illustrations for publication. Do you think there is any advantage to using LF over 120, 35mm or even digital considering the teenie weenie subject matter (the largest coin will be quarter sized---the smallest a dime?) and end use (a not-at-all-slick-magazine?)

Any thoughts on how the set up a shot? I'm thinking of using wax to hold the coin (s) to the inside of a plastic milk carton with one side of the carton cut away to shoot through so the coin will be bathed in a nice diffused light

Also, given the tone on tone nature of the subject --silver coins--what do you see as being the more dramatic presentation, B&W or color with color for the back ground or maybe even reflected off the coinage? Would it look too garish? Would B&W look to "clinical? I'm thinking I want to avoid a lot of contrast in order to make the bias relief on the coin "pop" but then maybe I should try APHS since it usually records incredible details. As you can tell I've never done this before---any advice (please?)

For this duty, I'd use the smallest format I could. For many coins, you'll be at 1:1 even with 35mm. Using 5x4, you'd be at 15x magnification which is rumored to be a serious PITA if you can even figure out how to get there at all.

35mm with a macro lens seems like a whole lot more fun. But as usual, YMMV.

There are several ways to shoot a coin and especially wrt how the lighting is set up.
This is an often described subject in macro-photo books.

A diffused light will work but the coin might end-up looking flat. By having a stronger light come in from one side there will be shadows emphasizing the structure on the coin if this would be of interest.

After glancing through many macro-books, I tend to like color more than B&W. As you say, playing around with some colorful lighting in the background is pretty cool.

I saw a picture once of a 'car brake-disc' that was shot in a way that made it look as if it was rolling towards you, leaning slightly to the left. The disk was silver colored similar to a coin but the background was rather colorful with some shadows. The depth of field made parts of the disk blurry which created the feeling of it moving.

Good luck with this project!

EDIT: You can do a google images search for coins and see what comes up. Here is an example where the lighting came in from the top of the picture to emphasize the details. As can be seen this light is only a bit stronger than the rest of the lighting but the effect is quite nice. And a polarizer filter could also prove useful for removing any unnecessary flare.

If it were me, I'd scan them directly. On any halfway decent flatbed, a 1600 DPI scan will generate incredible detail it would be difficult to match with film.

What Jack said. Even cheap scanners make amazing "cameras" for those kinds of subjects.

Yep. And it's also quite easy to render any number of special lighting effects in PS assuming you have a good exposure to begin with.

Which is why all those million-dollar-a-year car photographers from Detroit suddenly found themselves out of work. Even Kodak uses rendered images (not photos) of their film boxes, at least back when they actually advertised something as quaint as "film."

...a scanner and drop shadow in PS...so much for photography...I give up ;-)

That'll be Michael Kenna (http://www.michaelkenna.net/html/ads/index.html) out of work then...

for a diffuser, you can use one of those doggie-cones (http://images.google.com/images?client=safari&rls=en&q=dog%20cone&ie=UTF-8&oe=UTF-8&sa=N&tab=wi) from a vet - cheep --- 12$.
put the coins on whatever it is you want to photograph them on, cone on top
stick your 35mm camera in the part where the doggie's head would go through :)
put a flash (or 2) on opposite sides of the cone. the cone will diffuse the flash(s) and you will get nice even light ...

i once did a series on coins in my pockets and used this method to light everything -
that was when i had numismaphobia ...

have fun!

The oild school guys in Detroit weren't shooting anything like Micheal Kenna. But thanks for the link, that is some fine commercial work.

Way back when I was still doing professional photography (yes, son, they HAD invented the camera back then), I was assigned to a job that involved photographic coins. A softbox was just a little too flat. Direct flash was way too harsh. So I used a honeycomb grid over a 10" reflector as the main light direcly overhead and off to a 45-degree angle. Then I propped a white card on the lee side of the coin for fill. Worked great. But after 135 of those shots I wondered why they weren't just using a trained monkey.


That's when I realized that was EXACTLY what they were doing.
