Focus mask not displaying properly
I've recently noticed problems with the focus mask. I'm on C1 8.2.1, running under OS X Yosemite 10.10.2, and I'm seeing the same problem on both an iMac and on a MacBook Pro (Retina).
If I switch the focus mask on, green bits flash up on the photo in the viewer and then disappear again. The images in the browser get green patches on them, but in some cases the green mask is showing on areas of the image that are definitely out of focus. Sometimes if I switch to another image in the browser, the green mask then does show, and still does if I change back to the original image, but it is still showing the mask on parts of the image that are definitely not in focus.
In the screenshot below, the seagull is in good focus, but the waves in the background, at the top of the frame are well out of focus.

I though perhaps it had something to do with OpenCL, but turning it on and off makes no difference. The focus threshold in Preferences is set to the default.
Any ideas? Is this a problem with the latest update of C1? I'm not sure when it started happening, because I don't use the focus mask particularly often.

Ian,
FWIW I have never been able to work out how the Focus Mask selects what it selects and why. However a quick check on my Windows system running C1 8.2 suggests that the selections are few and small - completely the opposite to what you are seeing for the images I have loaded at the moment.
It seems to make little if any difference to the display if I change the default settings other than the opacity clearly has an effect on the Mask colour.
The relevance to any focus assessment is, I would say, obscure.
I may well be missing something exceedingly powerful but until I learn what that might be I'll leave it switched off and save a whole load of processing.
Somewhere in deep memory I have a vague recollection of seeing or reading something that suggested it might be a tool offering most benefits when working with Phase files but that could be a false memory.
HTH.

The focus mask is just looking at contrast over the image, with the preference slider determine the threshold. This topic has been discussed before. And believe the conclusion was that it is best used when tethering. As it works on the RAW file before any adjustments are made, so you can sharpen to the max, and the Focus mask will not change.
So if you are expecting the focus mask (it is not a area of sharpness mask), to change while you adjust sharping it will not do that. But if you are shooting tethered, and from the preview you want to see what is perceived to be in focus it might work for you then. Think of it as focus peaking with a adjustable threshold, but after the fact.
Now, as I learned about the Focus mask about a year ago, have not even bothered to turn it on. Does not give you anything useful after the fact. So it is possible that it is broke, and as I don't shoot tethered, do not care to investigate.
So because it just works on contrast and a threshold setting, it can display areas that are not in focus. So in the images with the waves, it may believe all the waves are in focus because of the contrast in the waves.

Robert,
Thanks, you have reminded me about the previous thread and the mention of tethering.

Yes, but in the past, although I have not used it much, when I have done so the focus mask has highlighted just the areas that are in sharp focus. You'll see from the other images in the browser that now pretty much the whole of the image is masked. Admittedly most of those visible in that screen shot are of similar subjects, but here is another one which also demonstrates the other problem that the mask sometimes appears in the browser but not in the viewer.

Whether or not you find it useful or shoot tethered (which I don't) the focus mask when I have used it in the past has worked as advertised, but now something seems to be broken with it.
(And I don't only shoot photos of seagulls!)

I've noticed the same behavior in 8.2.1 (build 8.2.1.5 0847f9a). I'm also having the Naming Format fields for both import and capture filled with white. If I select the field it show the correct data. 0 -

But the white naming fields seems to be a problem with Yosemite 10.10.3, but I have not updated to 10.10.3 - still on 10.10.2 because of that very issue being reported here.

Ian,
Sorry for any confusion.
I don't think you mentioned the tokens issue but Ryan did tacked on to his first comment (as quoted). So I thought I would try and point that part of the post to something that might help him.

Ian, as you I do not use the focus mask that often. I see similar issues of no focus mask at all or almost entirely coloured by the mask intermittently. I could be related to 8.2/8.2.1. However, in general it works on my system (8.2.1/10.10.2). Maybe it is sensible to file a support case? 0 -
Yes I probably will Paul.
Ian0 -
Support case now submitted number 175621.
Ian0 -
And here's what support have said. Hi,
We have a bug reported regarding this issue.
Our dev team are currently looking at it.
Thank you
Phase One Support
