How-To Photograph Artifacts

[The following was posted to the Archaeology Photo Gallery, but I'm posting it here as well for future reference]

Noticing that there is quite some interest in posting pictures of artifacts and whatnot here I thought I would create a write-up on how to photograph and present your finds so that we may all enjoy the fruits of your labor.

Hopefully you wont be offended by the basic and blunt nature to which I put some of the following, but in the interest of our viewership and everyone’s time certain things must by pointed out.

First, read the manual that came with your camera. I know this is pretty basic, but if you want detailed close-up pix and you can’t seem to do it, I’m sure the manual will explain how to be successful. TIP: I now have two digital cameras, manufactured five years apart, from two manufacturers, and both have a very convenient macro function – both of which use a “Flower” symbol to illustrate the feature. Selecting this mode allows one to move in very close to the subject and still maintain focus – just a few inches in my case. Most recently manufactured cameras come with a similar macro feature. Learning how to use it will benefit your presentations immensely.

Second, use an appropriate background matte to shoot your subject. The following pictures illustrate three classic backgrounds (the materials were expedient in this case – my aluminum clipboard for neutral gray, and black and white knit shirts for respective color contrasts). You will note that the subject looks rather different in each case due to the influence of the background, both on the camera, and on our own eyes. One should be able to go to any art-supply or photo-mounting store and ask if they have any scrap matte-board in the three colors that they would be willing to part with.







Third, size your pix in the neighborhood of 800 to 900 pixels maximum in either width or height and use a density of 200 to 300 dpi (dots per inch). (The above photos are 800 x 600 pixels at 300 dpi and compressed [to 4 on a scale of 0-12]). This allows the photo to fall full-frame in most folks browsers, and allows for quicker uploads for those who have slower connections – it also reduces the bandwidth that Jennifer has to pay for to allow us to use this site. If someone wants a more detailed picture then a PM can be sent and a link or a copy can be provided in return.

Forth, use some sort of scale – inches, miles, millimeters, it doesn’t matter so long as folks can get some sense of the size of the thing.

Fifth, use indirect, natural light whenever possible.

Sixth, if you have photoshop or similar software, use it to correct lighting and coloring errors, crop and resize photos, and compress if possible.

I hope this helps and that no one is terribly offended by my belaboring certain points.

Cheers,
Richard

I like how the gray background brings out the detail on this particular piece. I'll try a gray background on future images. Thanks.

Ya, the gray background provides the closest approximation of the actual color of the artifact, which is why, I think, that in B&W photography people use a neutral gray card to set up their camera before shooting a subject. But notice also that some aspects of the subject are rendered more or less clearly using the black and white backgrounds, which is also useful, and why when photographing artifacts it should be done as a bracketing mechanism, just like stepping up or down the exposure.

Understood. Thanks for the advice. By the way, what type biface is that?

That's a Late-Period point (bow-and-arrow technology) that falls in the general category of Cottonwood Triangular. See http://home.earthlink.net/~researchissues/chron.arrow.htm for information related to this technology in the far desert southwest. The material is a microcrystalline quartz (MCQ in Luedtke's parlance [http://www.amazon.com/Archaeologists-Guide-Chert-Archaeological-Research/dp/0917956753]), or "chert" in the colloquial. I've not seen a point, tool, or flake from this particular material before.

It's a pretty sucker!

Ya, it's pretty neat. Interestingly, I was recording a flake with a GPS, and while I was waiting for the datalogger to do its thing I looked over a couple meters away and said to myself, "Oh look, a point." Just lying out there all happy like. Here's what it looked like when I found it.

Nice. 8-) And good eye. That sucker blends in with the sand pretty well.

Is that a small draw where you found the point? Looks like very little recent erosion in the area...always good for finding the younger stuff.

I hear of very little Late Prehistoric material being found here in central Texas, and I think erosion has a lot to do with it. Collectors here in the area are just about as excited when they find Late Prehistoric stuff as they are when they find Paleo stuff. I'm still waiting on my first Late Prehistoric point. The area has been farmed and ranched since the mid 1800's.

The setting was essentially flat. Only a very slight gradient to the north (mountains in the background) in this part of the site.

Gotcha.

Here are some shots of artifacts not using the "standard" type backgrounds. When I photograph basalt lithics I will either shoot them in B&W or Grey Scale.
Light and technique will go a long ways and will produce some beautiful shots.

Nice artifacts!

Alaskan Lithics,

Have you got any examples of the basalt stuff shot in black and white? Nice photos btw.

Thanks

Alaskan_Lithics

Sorry for not getting back to you. I've been very busy with work and house projects. Now that the lousy weather has settled in I can get back to the fun stuff.

These fine lithics are from Dutch Harbor
