From: Bubba on 12 Apr 2010 19:59 I posted this in another Canon thread I started here, but no one's answered. The SX1 is available again, and it's the only P&S (from Canon) that has CMOS (lower-end P&S, that is). I will *never* buy another digital camera until I can take photographs where the reds/ pinks/oranges/yellows appear as blotched pixels--despite excellent exposure. If there are other CMOS P&S, from different manufacturers, I'd like to know who/what/how much. Thanks.

Until you're able to provide a clear example of whatever the hell it is you're whining about you're not likely to get an answer that you like. -- Ray Fischer rfischer(a)sonic.net

I don't see a reson to complain about the reds: http://www.flickr.com/search/?w=all&q=sx1+red&m=text DanP

Even then it is unlikely he will like the answer. There is a 2x1 chroma subsampling artefact that might cause problems for some flower images with fine black detail on a saturated red background. Most notably that the horizontal and vertical resolutions will differ by a factor of two so that two images take in portrait and landscape modes will show obviously different amounts of detail. He might find that a Foveon sensor with 1x1x1 chroma will solve hs problem, but since he cannot be bothered to show an example it is impossible to say. Like RichA he can be dismissed as a whinger.

Frankly, I see some flare in the fourth photograph in the first (top) row, where the bright red leaves are in bright sunlight, against a very blue sky. Thank you for posting all of these. I learned the phrase "red flare" from the photo-editing company (British) whose software I use, and it's only in overcast or rain that my reds do not appear blotchy. Great work! |
