I am asking for suggestions regarding the source(s) of these visual issues because I do not see them on my CRT monitor, a 5-year old Gateway 19" VX900, possibly a rebranded Hitachi. The adapter is a NVIDIA GEForce 2 MX400 with the latest software release. I calibrate the monitor about once a month, using the Nokia screen test software. I have my vision tested annually. I edit my pictures in a room with very low ambient brightness, with the shades drawn. My screen background is middle gray; the screen setting is 1024x768, 32-bit color. I scan the negatives at 2000ppi on a Nikon 4000 with the current release of VueScan, save and edit them as TIFs, and convert to JPG as the last step before transmitting them. The brightness of the scenes on my monitor matches my memory of the location. I made the images in question under fairly bright conditions, typically f/8 or f/9, at 1/250 on Optima 100, dependably a real ISO 100 film. I did not include a color reference chart. I do not have the technical or scientific background to fully understand what, if anything, is happening to the colors in the sequence of transformations, and what might account for the differences in perceptions. I shall be grateful for suggestions and/or explanations. Oliver
