I have done this before but totally forgotten how to do this.
I need to create PNG files to be used as masks on a web site with transparent shapes in the centre in Photoshop.
The mask should be transparent in the shape & saved as a PNG file for use.
I manage to create the background then change it to a ordinary layer then create the shape.
After that I seem to remember that it needed to be inverted but that button is not available for use.
Can someone assist? Probably something very simple that I am not doing.
Many thanks.
Bob
