Hi Jeff,

The color is purely interpretive. The camera delivers B&W date and of course the filter shows only a teeny slice of the red spectrum. The color is applied during processing in Photoshop using the "colorize" in hue/saturation.

Hi Alan,

Did you change filters between the wide field and close up view of the prominence? I was wonder what causes the color difference between the two images?
