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]

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]
