Standard cold light tubes that are not designated for VC produce mostly blue light, which is great for graded papers but they don't work well with VC papers, especially for low contrasts. By filtering, you are simply removing the light instead of modifying the light, because there is only blue to begin with. Even if you adjust light source and filtering, VC papers often give only passable results if you want very low contrast paper, unless the image is generally high-key. -- Ryuji Suzuki "Keep a good head and always carry a light camera." ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
