I just received a copy of the new Sony 20 mm f/1.8 G lens. I’ve ordered the similar Nikkor S. I’ll be testing both of them, separately and together. FOr those of you who’ve been following the color profiling work, don’t worry; I’ll be doing both types of testing at the same time. Just don’t… [Read More]

Visuals of GFX 100 strobe profile differences
In the previous post, I discussed how I created some color profiles for the Fujifilm GFX 100 using strobe lighting and ColorChecker 24-patch (CC24) and 140-patch (CCSG) targets. I showed you numbers and graphs that analyzed the accuracy of each profile. In this post, I’ll show you some images. All come from the DPR Studio… [Read More]
Designing color profiles for strobe lighting
I haven’t posted in the last few days. That’s not because I was taking time off from photo tech. It’s because I’ve been beavering away on how to measure and design color profiles. I’ve built more than 50 of them, learned a lot, found a few dead ends, and am finally reading to report my… [Read More]
CC24 vs CCSG CIELab values
The last two posts have been about my experiences using the X-Rite CC24 and CCSG targets and X-Rite’s Color Checker Camera Calibration program with both diffuse and direct solar illumination. I found anomalies between the two targets, which I thought might be related to lighting and glare. But today I discovered that, even with the… [Read More]
Profiling a GFX 100 with X-rite CC calibration, part 2
Warning! This post was created before I realized that the CC24 patches in the CCSG had different values than the CC24 patches in a real CC24 target. https://blog.kasson.com/the-last-word/cc24-vs-ccsg-spectra-and-cielab-values/ Yesterday I posted about my experiences using the X-Rite CC24 and CCSG targets and X-Rite’s Color Checker Camera Calibration program in diffuse illumination. Before that test, I… [Read More]
