So camera and printer companies get away with having unreliable color representation that cannot be anticipated or compensated or corrected for at one stop different exposure. Meanwhile consumers fall for the marketing pitches touting deeper color spaces (14 bit RAW, etc). If we did not cling to the myth that digital capture can be accurate (if we pursue color calibration at every step in the process for example), what functions might a computer-based imaging system be free to perform? I had to separate some of the immediate answers to that question out into a follow-up post on features Canon and Nikon should be putting into their cameras if they would only stop trying to simply emulate the old hunks of steel.Jeff Sullivanhttps://www.blogger.com/profile/02256796802024209239noreply@blogger.comtag:blogger.com,1999:blog-33143996.post-7631432561030946912011-09-13T12:13:38.417-07:002011-09-13T12:13:38.417-07:00Max, If Canon and Nikon stopped trying to simply e...Max, If Canon and Nikon stopped trying to simply emulate an analog film camera, what features could and would they put inside? The whole approach of capturing a single exposure is a severely "dumbed down" version of that our eyes capture and our brains perceive. How could a camera capture a scene in a way more compatible with our perception onsite? First of all you'd have a different exposure at every point in the scene, then you'd do some post-processing to interpret and reassemble the scene as a whole. Film cameras couldn't do that. Today's computer-based cameras could. Apple's iPhone HDR mode is a good example of this, and it should be extremely embarrassing to Canon and Nikon that they seem to be behind in this emerging area of photographic imaging.Jeff Sullivanhttps://www.blogger.com/profile/02256796802024209239noreply@blogger.comtag:blogger.com,1999:blog-33143996.post-49125875770493205762011-08-29T09:15:08.338-07:002011-08-29T09:15:08.338-07:00What are you talking about?

Are you proposing something or just complaining about the weird way digital exposure works?<br /> How can you say that we lack color memory? There is a reason we name colors things like Fire Engine Red and Sky Blue... Because people remember what those colors are, and understand the reference.Andrew Webbhttps://www.blogger.com/profile/00241990529610149303noreply@blogger.comtag:blogger.com,1999:blog-33143996.post-91130647722302165322011-08-28T23:58:07.556-07:002011-08-28T23:58:07.556-07:00i have no idea what you're really trying to sa...i have no idea what you're really trying to say.
