The new semester starts for me tomorrow at 7 p.m., and I am planning to give a short, simple quiz - multiple choice - to get a sense of what my students do and don't know about the basics of photography - mechanics, not history or aesthetics. I don't care if they've ever shot film, know anything about processing or printing. What I want to know is what they know about using a camera - digital or film. I have plenty of questions, but I wonder what any of you would ask... Thanks - B. D. P.S. I don't care if they know which version of the pre-asph 50 Summicron is considered the best by Erwin Puts, nor do I care, or could I ask, if they know what a NOOKY is...:-) -----Original Message----- From: lug-bounces+bdcolen=earthlink.net@leica-users.org [mailto:lug-bounces+bdcolen=earthlink.net@leica-users.org] On Behalf Of Aaron Sandler Sent: Wednesday, February 02, 2005 2:59 PM To: Leica Users Group Subject: RE: CC filters (was: Re: [Leica] Re: LUG Digest, Vol 29, Issue 124) BD, you've reminded me of something I've been wondering: Why do folks equate filters on a film camera to in-camera processing in a digital camera? It seems to me that with digital: Light enters lens, hits sensor, software in the camera corrects color How is that different from: Light enters lens, hits film, film is scanned, software in computer (eg, PS) corrects color If a filter would help in the pre-light-hits-film phase, why wouldn't it help in the pre-light-hits-sensor phase? Inquiring minds want to know. -Aaron >There are definitely times when PS offers the best, if not the only >option for color correction.
