Capturing digital images
Digital cameras and camcorders are inexpensive enough that they really are necessary items when creating
material textures. Although Photoshop can be used to create many unique and interesting textures, a digital
image of riverbed stones is much more realistic than anything that can be created with Photoshop. The
world is full of interesting textures that can be used when creating images.
Avoiding specular highlights
Nothing can ruin a good texture taken with a digital camera faster than the camera’s flash. Taking a picture of
a highly reflective surface like the surface of a table can reflect back to the camera, thereby ruining the texture.
You can counter this several ways. One technique is to block the flash and make sure that you have enough
ambient light to capture the texture. Taking pictures outside can help with this because they don’t need the
flash. Another technique is to take the image at an angle, but this might skew the texture. A third technique
is to take the image and then crop away the unwanted highlights.
Tip
The best time to take outdoor photos that are to be used for materials is on an overcast day. This eliminates the
direct shadows from the sun, which are very difficult to remove. It also makes the light gradient across the surface
much cleaner for tiling the photo. n
