I think I\'ve been having some issues with my 4x6 size Singh-Ray 5 stop ND filter. I seem to get a pink/purple or red color cast whenever I use this filter (the severity depends on the original skyl.
Here are some examples of just using a Singh-Ray ND grad, ND Grad plus 5 stop ND two shots and then right after with just the ND grad again. NOTE: I didn\'t bother cloning out the marks from the dirty sensor.
Anyone experienced this In this particular case the differences in exposure were about 2 sec expoures without the 5 stop Grad filter and 30 seconds with the filter. I thought it may be bcoz of moving clouds, but there is no way that there was that much movement that there would be a color cast over the entire sky and part of the peaks. Moreover, I also experienced this with much shorter exposures in the past. I also found that if i switched to my ND Vari-ND filter, i wouldn\'t have an issue. The problem is the Vari-ND is to too thick (i have slim version), to use with ultra-wide angle lenses.
Does this look like a quality control issue - should I be calling Singh-Ray
