I saw this in Car and Driver, of all places. The source is Pablo Picasso. I think it’s a good thing to keep in mind when the little voices in our heads say, “No, don’t do that.” The chief enemy of creativity is good sense.
Testing for ETTR, part 25
From the mailbag: After 24, or so, posts, me thinks it is time for a PhD (push here dummy) summary…..that is a horsey, horsey, ducky, ducky, big animal pictures review of ETTR methods and what works best with what kind of camera…..dontcha think…?? I’ve summarized most of what I’ve learned about in-camera histograms and ETTR… [Read More]
Testing for ETTR, part 24
Iliah Borg writes: Knowing that green is more sensitive, one of the tricks to equalize channels better while shooting with daylight/flash is to use a magenta filter, about 30 to 40 percent depending on the camera (CC30m, CC40m; P instead of m if the filters are from Germany). This will also improve colour reproduction if… [Read More]
Testing for ETTR, part 23
Ever since I starting working in camera space, I’ve had what I needed for a true one-step UniWB calibration procedure, but I didn’t have a delivery mechanism, since the procedure required inverting a matrix, and I was using Matlab for that. I poked around and found that Excel can invert matrices, and multiply them too…. [Read More]
Testing for ETTR, part 22
Iliah Borg has pointed out that he does his UniWP calibration in a monitor space with native primaries and a gamma of one. Not using the native primaries might be one source of inter-channel crosstalk. To find out if this is significant on my NEC PA301W monitor with the D800E, I made three exposures at… [Read More]
