Trevor, thanks very much for your response. Persuant to your suggestion, I need to follow-up my original question with some questions regarding copy and paste. I made the shape and attempted to paste it into the SO Mask. Instead of pasting into the mask, it pasted the shape onto a separate layer. I looked at two tutorials (Steve Patterson https://www.bing.com/videos/riverview/relatedvideo?q=how+to+paste+into+a+mask+in+photoshop&mid=856CBB9A3A4A9933BC19856CBB9A3A4A9933BC19&FORM=VIRE and Julieanne Kost https://www.bing.com/videos/riverview/relatedvideo?q=how+to+paste+into+a+mask+in+photoshop&mid=A67B79B8CA1F1E9AD98FA67B79B8CA1F1E9AD98F&FORM=VIRE ). Both address this issue. Following their instructions, after copying the shape from its layer, I pressed the alt key (Windows) to reveal the mask; then I pasted. In each of their tutorials, this successfully pasted into the mask. In fact, I encounter the same problem even if I’m just trying to cut from one layer and paste into another w/o reference to a mask. In the image attached, I tried a simple experiment. I created a yellow rectangle on one layer and a smaller black rectangle on a second layer. I then copied the black rectangle from layer 2 and pasted into the yellow rectangle on layer 1. Instead of pasting on to layer 2, PS created a new layer, layer 3. Moreover, the black rectangle on layer 3 does not align with the source rectangle on layer 2. I also converted layer 1 into a SO, created a smart blur filter with a mask, copied the black rectangle from layer 2, pressed the alt key to view the mask, and attempted to paste into the mask. There was no result at all. Nothing was pasted into the mask. No new layer was created. Bottom line, as you suggested, I made a shape, but I was unable to paste it into the layer mask. It seems ridiculously simple. Can you see what I’m doing wrong? Also, I reset Preferences to make sure the problem is not something flaky with PS.
