>>2147243What type of camera do you have? I don't have much experience with recent digital cameras because I don't like them but I'm guessing that they still mimic the behaviour of film cameras.
If you are having problems with lighting and grain I would say that you are using the incorrect film speed setting. The higher the film speed the greater the noise. However slower film speeds require more exposure. Try to use natural light. Tungsten lighting can cause the picture to look yellow, flourescent lighting will look white and paloured, this can be solved by changing the lighting settings on your camera or using something like Photoshop. If you are having problems with camera shake, use a tripod and set the camera timer, you're taking pictures of static objects so try to use an optimal film speed to minimise grain.
