I have loaded the trial version of Photo and seem to have a problem with soft proof. As a test I exported some images from Capture 1 as PSD files. In Photo I add ( at the top ) a soft proof adjustment layer, select the canson Photo Lustre Premium RC profile. I can turn the layer on and off and there is no perceptible difference. With Capture 1 and Photo running concurrently on the same machine, same graphics card and same monitor I can switch between the Capture 1 image and the Photo image. Without soft proof on in Capture 1, the Capture 1 image seems to be the same as the image in Photo irrespective of the soft proof setting in Photo. When I select soft proof in Capture 1, the image changes significantly, this does not happen in Photo. The printer is a Pixma Pro 100S.
There is clearly something wrong somewhere. I could have made a mistake but the process seems simple. I get the impression that I have not got any printer ICC profile to work in soft proof. I have not tried printing but I will not try that until I get soft proof to work. I have about 1 day left on the trial and I suspect that I am going to run out of time
