Chromatic Aberration question

I used Color>Chromatic Aberration on a recent image in an attempt to deal with some red/green fringing (Oregon sea-stack against a bright sky). I was able to control the issue relatively well with Red Shift of -0.0387%. However I later discovered, on close inspection, a bright line around the edge o...

Re: Some preliminary information on PWP 8.0

Jonathan, So looking forward to seeing the new product. The tree/branch aspect is of great interest (as well as the Layout Transform as I use that a lot). I have broached this topic before, so will ask - Has there been any consideration given (either now or for in the future) to tablet compatibility...

Re: Layout Transform

Another Layout question. If I have a 48 bit colour image active, and I do File>New Image and use the Colour Picker to identify a colour, the resulting solid colour image is 48 bit. Seems logical. If I have a few images open and one active (all 48 bit colour) then open the Layout Transform to generat...

Re: Layout Transform

Dieter,

All good points.

Because I am curious (and I admit, a bit anal!!), I often like to know things like this regardless of whether it has any real practical value.

Cheers,

Marv

Re: Layout Transform

Dieter, I was not necessarily trying to compare the same re-sampling method used by Layout against Resize, but more was interested in determining if there was a quality difference between the method used by Layout and the Resize re-sampling method I typically use (Lancsoz 8 x 8), and whether the dif...

Re: Convert an Image to greyscale and its Histogram

Den, Excellent explanation. But a question for clarification. For color 1, why did you enter 0.2510 (as opposed to just 0.2500) and 0.1960 and 0.2510 (rather than 0.2000 and 0.2550 as reflected in the readout tool)? Man, I got to tell ya, some of this under-the-hood stuff can be quite confusing (and...

Re: Convert an Image to greyscale and its Histogram

I have tried all the suggestions, with the following results: The color curves - could not get a "clean" yellow, no matter how hard I tried and where I moved the point(s). The results were similar to the "muddy" green (or whatever the color is) that shows in Den's example of the ...

Re: Layout Transform

Jonathan, Out of curiosity, I tried two methods of resizing images for the panels. Each original image is 4666 pixels square. Each of the nine panels is 2333 pixels square. First I kept the images in their original size, identified each, in turn for its panel, and let the transform resize. Second, I...
