-    The following information was compiled from a series of responses to a post on the CCP4bb on October 21, 2009 by Andrew Torelli who asked about free utilities/programs that could convert X-ray diffraction image file formats to a graphics file format that could be edited by programs such as Photoshop.  The specific responses are worthwhile to read and can be searched in the CCP4bb archives using the subject query "X-ray diffraction image --> .jpg".  The summary is below:

+    A notable consideration (provided by Jim Pflugrath) is that "A JPEG has fixed colors for the pixel values.  A diffraction image has to use a viewer to convert the pixel values (counts) to a color.  One problem with just using a converter to jpeg is how to convert intensities to color (i.e. computer display values)."

      Additionally, Morten Kjeldgaard noted that opening saved images (particularly TIFF images) in Photoshop will require "Image -> Adjustments -> Equalize" to see anything other than black.
