When photographing your work consider the lighting consistency and reduce subsequent shadowing that doesn’t confuse the photo, this applies to three-dimensional work as well. The colour of the room can change the nature of colour, but as artists you are no doubt aware of this. Generally speaking using direct flash isn’t advisable as it tends to wash out the colour and flatten the image.
Three-dimensional works are especially effected by this flattening effect of the flash. Generally don’t have the light source too high above the work as the shadows are likely to confuse photo. Having unrelated shadows in the scene can have the same subtractive effect. More than one light source is good. A softer light approaching the object from behind, off the side can create nice highlights along edges and reduce dark edges when undesired. A second, stronger light approaching the object from the front-side, above eye level acts as the main source of illumination. Sometimes a nice touch is to make one of the light sources warmer than the other. Have fun trying different things out, but I digress into the work of photographic art.
Additionally if you are taking you’re photos of work behind glass take the photo on a slight angle. This can help remove you and the camera from the photo. This is especially relevant if the flash or other lighting such as lights, windows etc. are reflecting in the glass. As long as you don’t create too much of an angle and send us the highest resolution you can, we can straighten the photo up with relative ease. Too much angle will cause linear distortion and blurring. If the photo is too small it may cause some overall blurring. Try to position yourself and the frame so that there is as little reflection as possible.
