I was having trouble with the shadows turning magenta and always adjusted them out in photoshop but was having trouble with streaks in some 6x9 negatives. I decided that the calibration part of the glass might be dirty and the bottom of the glass did show show some fogging up. I found out how to remove the top (2 screws under the top cover hinges) and cleaned it with windex. Now the magenta shadows are gone but does still have overall magenta cast which is easier to deal with.
One thing I can't understand. When scanning a 4x5 transparency at 100% there is just a little grain but scanning a 6x9 Fuji neg there is tons of grain. I thought that maybe because I was using NHG11 800 speed dated in 2001 but ran some very fresh Fuji pro160C with same results. Also the streaks are still there on the negatives but not the transparancies. The negs were developed by the largest pro lab in the midwest. It's not enough grain or streaking that it will show up in an 8x10 I just printed. Tonight I can post some pictures to show what I mean.
