Hello everyone ! Browseing the technical information on Kodak films, I saw a section talking about "Gelatin Filters". I have never used or seen this gelatin filters before. Could someone give me more details about them. Are they similar to cokin or the lee filters ??? The other question I have is, the F90x (N90x) has TTL metering, but is it still necessary to make exposure compensation when using this filters ? Or can I rely on the camera meter ? (I use F90x) Thanks in advance for your input. Anand.
