Re: A visual center

I don't know whether it is a good idea, but if it is, it might be better to put the choice in the Layout transformation on its dropdown menu for Alignment of a panel. One reason I don't know about the idea itself, which is new to me, is that brief search on the Web shows that visual center is define...

Re: Histogram of a Preview Window

Hammering the Histogram tool on the Apply window of a transformation is not good enough?

Re: Clipped pixels

I think that the reason may be that clipping warning operates on HSV-V channel: shadows clip when HSV-V=0, which also means that all three RGB channels for that pixel also need to be zero. There may be more shadow pixels in each of the RGB channels that are zero just in that channel, but non-zero i...

Re: PWP 7.0 and MIS UT-3D inkset

I am wanting to use a variable tone black and white inkset developed by Paul Roark and sold by inksupply.com (referred to as MIS) called UT-3D. One is able to create printer profiles using Quadtone RIP but on the website describing the inkset, the following statement is made; 'Requires use of Photo...

Clipped pixels

Set Shadow clip at 0 in Preferences.
Color | Extract channel

Extracting red, green, and blue channels successively, the preview for a certain shot shows many clipped pixels, but the result shows few clipped pixels. Intended behavior?

And apparently, a pixel is clipped if any of R,G,B is 0.

Re: Printing with an Epson printer profile as the custom profile

You don't mention the paper. I confine my papers to those for which the manufacturer offers a profile for that paper and my Epson printer, an R2880. In practice that has not been a confining factor: all the good paper makers, with the possible exception of Strathmore, post profiles online. In the ca...

Re: Colouring an image

Can you give some context to the problem you are trying to solve or post a small version of your image. Yes, it is not clear how this job relates to serious photographers (alluding to DLC's motto). If you know any programming at all, it would seem easier to define a 6000 x 4000 matrix, code the bla...

Re: ProPhoto for RAW-Output

Camera manufacturers generally try to produce RGB values compatible with sRGB or Adobe RGB so it makes sense to use whichever of these color spaces you specified in your camera settings Thanks for some light on a mystery I wondered about. Most enthusiast and professional cameras have a choice of sR...

Re: ProPhoto for RAW-Output

As you note, for such rare exceptions where demosaicing into ProPhotoRGB makes sense, you can start with something like dcraw or Raw Therapee. I ask out of curiosity, how do you find that an image has intense yellows beyond Chrome 2000 D65?
