Digital Light & Color

Jonathan, Thanks for the explanation and the comment on the incompatibility of measuring DR using HSV V or HSL L in the brightness Curve. However, what method do you suggest I use to ensure an image has not exceeded the 0% or 100% DR subsequent to the use of Colour Balance, or is that transformation...

Thanks Jonathan, After doing colour balance, I have usually reviewed the DR by opening the Gray>Levels and Colour transformation and referring to the grayscale DR readout (without making any changes to the transform). Although there is a Colour Space choice of HSV/HSL lower on the transformation box...

Den,

Thanks for the link. I had tried to find that white paper yesterday but couldn't seem to locate it.

Thanks Han, You are quite right. For some reason I thought the default was for auto white and black balance without contrast extension, but it appears contrast extension is part of the default state of the transformation (wonder why that is?). However, when I now disable the contrast extension by cl...

Hello, I have an image of a foggy sunrise (attached if I uploaded correctly...first time with this) that I converted from RAW into a TIFF and opened in PWP. The "Grey - Levels and Colour" transformation gave an initial dynamic range of 2.4 and 98.4. However, after using the Colour Balance ...

I hear ya. I have used PWP for years (since version 2 I think) and it is my most-used image editing program, however as in this case, I am often reminded of how little I really know.

Bob,

I just tried your suggested method and it's exactly what I was looking for.

Thanks for the help. Very much appreciated!

Hello, I doubt this is a PWP specific question and I'm not even sure my question has an easy answer. I am trying to do the following: When I open one of my images (6048 x 4032 ppi) and crop a 20 x 13 pixel section and enlarge it fill the screen, I get an image of 20 x 13 solid coloured squares, each...

Thanks. I will give that a try.

From what I can figure, when applying a mask to an image, the histogram of the image continues to represent the distribution of tones throughout the entire image. To better manipulate the tones in just a portion of the image, is there a way to have the histogram reflect only a portion of the image, ...
