white balancing

A lack of proper color temperature balance between the microscope illumination source and the film emulsion or electronic image sensor calibration is the most common reason for unexpected color shifts in photomicrography and digital imaging. If the color temperature of the light source is too low, images will have an overall yellowish or reddish cast, and if the color temperature is too high, images will have a blue cast. This interactive tutorial explores how the white and black balance settings on a digital camera system can be utilized to adjust color balance in digital images.
