]]> Comment on Maze artifacts in raw files from Nikon by Sebastian http://www.supersoftcafe.com/2008/06/28/mosaic-noise-in-rawnef-files-from-nikon#comment-8 Sebastian Thu, 17 Jul 2008 07:22:40 +0000 http://www.supersoftcafe.com/?p=16#comment-8 Hey I got this link from a fellow flickr user and I've discovered this effect as well. Similiar situation as Andrew: iso 200 1/640 f22 I discussed the issue here: http://www.flickr.com/groups/strobist/discuss/72157604961230744/?search=Maze and mikko rainkainen also pointed me to dcraw. Although I didnt use dcraw to PP the shot again, I haven't had any problems letely, mainly based on the fact that I haven't attemptet any lowkey shots any more. ;-) My suspicion is that it the demosaicing artifacts are connected to a large f-stop, fast shutter speeds combined with large amounts of light (My SB 600 was on 1/2 power) in a short time, which confuses your sensor. This could be worth to try and reproduce the effect to prove the consitancy of this suspicion... But it's good to know that there is software out there that will do the job! Thanks for evaluating the topic! Hey I got this link from a fellow flickr user and I’ve discovered this effect as well.

In general the artifacts seem worse either at higher shutter speeds or when using the standard lense. I have read some reports of high key being the problem, and I have a personal theory that it might be down to the lossy raw compression employed. I might buy a D3 later this year, depending on how the prices go. So I'll report back here when I have had a chance to experiment with that. These test images where taken with a D40.

The effect is extremely pronounced in PS CS3, and not quite as bad (but still there) in Nikon's Picture Project. I haven't been able to figure out the cause, but the last time it happened, I was shooting at 1/500 sec with off camera flashes, using Cactus V2S triggers. If I shoot at 1/400sec or slower, the problem goes away. So maybe it's related to sync speed. Thanks for the tips on fixing it. Another way is to resize the image in photoshop with the bicubic resampling, but I need to experiment more to see which works best. Fortunately it doesn't happen that often! Does this happen in the higher end Nikon's? I'd like to upgrade at some point in the next year and would like to avoid any camera with this problem. I’ve seen this a few times with my D40.
