Yesterday I reported on some of the processing the D810 does to raw files, apparently in an attempt to reduce noise. A few weeks ago, I published these curves which look at dark-field noise vs shutter speed with the in-camera long exposure noise reduction on and off. You will note that there is some processing… [Read More]
Nikon D810 long exposure noise reduction
There has been some discussion on the web about long-exposure noise reduction in the Nikon D810 that occurs even when the menu setting for such process is set to off. I have seen some indications of this kind of processing in my dark-field versus shutter speed tests. Now that I have a tool for analyzing… [Read More]

“What war?” you say, “CMOS won that war a long time ago.” If the criterion is chips shipped, I agree. But CCDs have their fans in the photographic community, and they tend to be vocal. I’m from Missouri about the supposed color rendering advantages of CCD’s, and I really don’t like the poor dynamic range… [Read More]
Easy ETTR for Canon users
From the mailbag: Thanks for the blog series on ETTR and UniWB. I’m not sure, but I may have been among the earliest to describe the trivial way for UniWb with Canon: lens cap black or totally blown over-exposure. I was unable to easily find the date on your blog article. You may or may… [Read More]
Is ETTR worth it any more?
There have been a flurry of statements recently on photo fora that exposure to the right (ETTR) is an obsolete concept. The argument goes that, while it may have been useful in the past, modern cameras have so little noise that ETTR is currently a waste of time and brain cells. If you buy that… [Read More]
