As you mentioned, your system seems light on RAM.
Have you tried running it on a small image as a test to see if maybe you have resource exhaustion?
Thanks Noel, I'll give that a try tomorrow. In the past, I've usually had a message telling me that a particular filter or action cannot be performed due to lack of memory. Nothing this time, just no effect.
thanks again. Will let you know.
Keep in mind one other thing... This filter is not fast - it will sit there analyzing your image for quite a while before showing you results. Watch the little spinner.
Thanks Noel, but I don't even get the little spinner. Just no visible effect. Waited two minutes on one occassion. Nothing. Will try a smaller image as you suggested today. All I get when I move the cursor over the image after initiating the focus area panel is a circle with a diagonal line though it, which disappears when I move the cursor back to the focus area panel.
Thanks again for the feedback.
Okay, I reduced the size of the image to something small (max dimension of 1200 pixels), and this fixed the issue. The filter now works. Looks like I need more RAM.
Not that impressed with its operation though. It selects areas that are in focus as well as out of focus Even fiddling with the sliders. I think I could have achieved a better result manually with the usual selection tools.
Anyway, it's working.
Maybe Adobe should warn people that this filter needs a lot of RAM to process large files? Also, didn't see a mention anywhere that hardware acceleration is required. Or does it?
Thanks so much Noel.
You're welcome, and I agree, it should at least warn you if it comes up short of RAM.
In researching a bit for my answer above, I set out to try the filter on a number of images, some of which should have been "no brainers" for the filter to process, and I have to say, for me it did what it did for you on a couple of occasions. It seems to have trouble with the transition between sharp areas and their edges that border on quite smooth backgrounds.
I hope Adobe continues to refine the operation of this filter.
