Reminds me somehow of photos I've taken at Shark Valley. Something about the lighting and the foliage...
When Photoshop acts up there are some basic things people often advise to try:
1. Check to see if everything's up to date (Photoshop updates, driver updates, etc.)
2. Clear Photoshop's preferences to defaults. This of course means you'll have to remake all your preferences changes.
This was taken at the Alligator Farm in St. Augustine Florida. Slight post processing in CS-5 and NIK.
All is up to date. Everything was working OK earlier and then this appeared. Could I have changed some setting. It doesn't make sense that it should appear. I'll wait until I return to default.
1) Make sure Photoshop has all the latest updates installed.
2) Make sure your video card driver is up to date
My first guess would be the video card driver just not drawing the marquee correctly.
But I think I recall an old (very old) bug we fixed that would cause selections to draw incorrectly like that.
I am using a MAC with Version 10.7.4, with 8 GB RAM. Card is ATI Radeon HD 4850 512 MB. Apple software as well as Adobe are up to date. Originally it seemed like this happened after I put selection on mask and then went into the Mask Panel and slid Feather and Density. As I do this process again I can't get the rectangle to appear in the selection. Maybe it just cured itself.
Thanks to all
