Re: Some preliminary information on PWP 8.0

This is exciting. Two minor items from PWP 7: 1. When I crop, I almost always use the Golden Rule guide lines. However, I cannot get the transformation to remember this choice as part of the saved default. 2. Selective Color Correction is one of the most precious tools in PWP. Does it make sense to ...

Re: All Good Things Come to an End

I would not have got fairly deep into photography as a hobby if I had wrestled with the big gorilla Photoshop. By chance I came upon PWP, which gets the credit or blame. Its transformations are simple yet with such depth that every few months I get into something about image development that I did n...

Gray Zone Adjustment

A slight rework for DLC consideration: add a 4-zone adjustment and put the 2, 3, and 4 zone adjustments into one dialog with choice of number of zones. Hold one choice as the user-set default upon opening the dialog.

Why? Often enough I work on the second highest quartile, roughly.

Re: Color Balance

Just to restate the main point here, the basic operation of a raw developer is demosaicing: it takes the data that the camera recorded through a color filter array (almost always Bayer, but Fuji X cameras use Fuji's X-Trans array) and creates an R,G,B triplet at each pixel. Then post processing mani...

Re: Rendering Intent

Ok,I did a search and instant study, making me a Web-certified expert. Apparently, BPC aims to lighten the darkest shadows in a smooth way that keeps more detail in them. So if you want Relative rendering intent, it seems one should have BPC on most of the time. BPC is not relevant to Perceptual ren...

Re: Rendering Intent

Just for completeness, I note that we have one more choice: Color | Profile | Rendering Intent, and the dropdown menu also has Preserve Identical Colors + Black Point Compensation.

As mentioned, readouts of a single pixel (1 x 1) from random locations around the image are all 0,0,0.

Re: Composite | Absolute Difference versus the eye

Same result for the sRGB conversion whether a proofing profile is enabled or not. However, your reply prompted me to save both sRGB conversions of a photo, open Fast Stone, and toggle between them, one on top of the other, so to speak -- no difference discernible! I guess my eyes and brain fool them...

Re: Composite | Absolute Difference versus the eye

Yes, I followed all the settings you specify. So what explains the paradox that the two sRGB results look different to my eye but the Absolute Difference, or Subtract for that matter, is black, and Readouts, 1 x 1 pixel, from random locations around the image are all 0,0,0?

Composite | Absolute Difference versus the eye

Paradox: I work in Adobe RGB with a wide-gamut monitor. Once finished with a photo and when I want an sRGB version, I put the NEC PA monitor back to sRGB and do a Change Profile twice for comparison, once with Maintain Full Gamut and once with Preserve Identical Colors Plus Black Point Compensation....
