White balance

Lamps have a different color than sunlight. It is more yellow rather than white. You'll need to correct that if you want realistic photo's. Most digital camera's have options to change the so called white balance. My Pentax has menu options for daylight, shades (which are usually too blue), bulb or halogen light (too yellow) or fluorescent light (too green). Setting the camera's white balance will work better then correction with Photo Shop or Paint Shop.

	This photo was made in standard daylight setting of the camera. Lighting however was provided by the three afore mentioned halogen desk lamps. Light is too yellow.
	With this photo the camera was set to correct the white blance of the bulb light.
