Last time, I noted that photographs of the exact same object, even under the same lighting conditions, can come out different colours. That is one of the two reasons why I am not persuaded that the very different colours of my photos of the two Supersaurus scapulae is strong evidence that they are from different individuals.

In part 5 of the Supersaurus series, I made the point that my photos of Scap A and Scap B seem to show them as being very different colours, suggesting different preservation. However … The first of these points has just been brought home to me by an unrelated experience. The rendering on an outside wall of our house had come loose, and needed to be removed and replaced.

Years ago, the roof of our summer-house suffered some water damage and had to be replaced. So I converted it into a woodshed which I attached to the side of our house. As well the store for our firewood logs, it’s also where I keep many of my decomposing corpses — most of them in boxes and bags, a few of them not.

Somewhat lamely, this is the only slide I had in about lighting. I left it up while I talked about the most important points, which are: Don’t use a flash unless you absolutely have to. If you can swing it, the common convention is to have specimens illuminated from the upper left.* If you have the time, it’s not a bad idea to bracket your Goldilocks shot with brighter and darker photos, by fiddling with your camera settings.
