Wow. Great picture! I really like this kind of minimalistic, near-abstract thing. The weird things you are seeing are just quantization artifacts. I'd guess that the photo is slightly underexposed: These artifacts get more pronounced at lower levels, where each bit has to represent a larger portion of each f-stop. By "underexposed" I mean that the original shot was probably exposed properly as far as the "look" of the scene goes and didn't have any clipping, it just didn't have the histogram pushed all the way to the right. With bright photos like this, pushing the histogram to the right yields an overly-bright, washed-out-looking image, but one that can be brought into line in Raw conversion. Without those artifacts (usually). You've really got a "worst case" situation with this shot because you have a really gradual transition of a fairly narrow range of tones over a very wide area. > Or is it just me.... Well, that's always a possibility, too. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
