There’s an interesting thread in the MF forum of DPR. A Youtuber says that these days, a new camera offers only marginal gains, not a material advantage. The basic argument is that we have passed the era of quantum leaps in performance, and that today’s cameras are so capable that you can do almost any… [Read More]
The Nikon Zf has both an AA filter and pixel shift
In the previous post, I said: …I’ll accept for the purposes of this discussion that no camera manufacturer uses pixel shift on cameras that have AA filters. I don’t know that that’s true, but I can’t think of any counterexamples. Erik Kaffehr found a counterexample, the Nikon Zf. In the spirit of scientific reproducibility, I… [Read More]
4-shot pixel shift and AA filters
This might turn out to be just one more hopeless “there’s something wrong on the Internet, and I must fix it” posts, but maybe it can rise above that. I’ll do my best. In a DPR forum, there is a thread about 4-shot pixel shifting. Under that protocol, which is available on Bayer color filter… [Read More]
Why are my developed files so big?
This is a pretty basic question, but I’ve been asked it a few times, and so I’m creating a post to which I can refer people. My raw file is x bytes, and when I develop it, it’s 3 times that big. How come? I’ll first answer the question assuming both files are uncompressed. Most… [Read More]
Visible noise and CFA filter spectra, part six
I’ve added 17 more cameras to my test suite. The results: Same trends apply. Older CCD cameras are worse for SMI, except for the NEX-5N, which has lousy SMI. Not a lot of difference wrt the CFA’s effect on noise.
