Could someone please walk me through the steps to make
a mask in Photoshop 7 that will work as a custom shape
in AMS5? I have tried multiple things, but every time
either the entire shape is missing (nothing showing at
all) or the whole page shows (not just the shape).
I have followed the instructions on both this forum and in help and was unsuccessful. According to those instructions all you have to do is create a shape that's white with the rest black and you've made a mask. I also did a quick mask and a layer mask in photoshop 7, but having not worked much with masks in the past, I'm not entirely sure I did it right. If I use a mask from the gallery it works great, so I know it's something I'm not doing right in photoshop.
I am attaching the png file of the mask that I've created. If someone would like to create a custom shape window with it, you can see what my problem is.
I'm thinking it's something basic and simple, but it's driving me crazy and I would appreciate it greatly if someone could help.
