I think I have absolutely lost my mind.
I have a simple project of taking a family portrait that I took, cropping it, adding a creative border by way of erasing with a brush to transparency and then adding a drop shadow to that for a slightly raised look. This is not unusual at all. I'm using
PSCS2
I opened the photo
saved as "<photo> with border".tiff
chose erase, brush mode, selected a brush
erased some of the outside of the photo to transparent background
went to layer:styles:drop shadow and edited the variables but nothing is showing up either in the image or or in the little preview box in that window.
I thought it might have been the computer or the app but I tried it with some text and it worked fine. I can't seem to do it with the image.
Did I miss a step? I selected the layer but do I have to actually select pixels? Actually, I did both: select layer and then I tried it with selecting pixels, neither worked.
I am going for a walk to the park with my daughter, maybe that will help.
