Wayne beat me to it! Cory, if your camera has a 'White Balance' adjustment, or automatic 'White Balance', you can take the pics indoors, under a desk lamp or similar. You'll need to use a minimum of a 100 Watt bulb, and set the 'White Balance' against the white background you are using; this should counteract any yellow/orange colour cast from the artificial light. Failing that, a Daylight Simulation bulb (a 'special' blue light bulb) will do the trick. These should be available from art shops. Saves having to wait for decent daylight.
You'll probably find that flash will be too strong, or could cause a colour change towards blue.
Sorry, I'd hoped to get the Photography Guide finished in time, but I'm currently re-writing it, to get rid of some of the b*ll*cks!
It WILL be done soon, in time for the next GB.
Terry.
