Replace my canvas with a transparent layer

[Claudine]

Hi, :)

I would like to replace my canvas with a transparent layer for a step in my work - later I would like to put the canvas back. It will allow me to create effects with another layer placed below displaying my photo project. Yes I would like to mix painting and photo thanks to the eraser tool.

Thank you for your help :)

... Now I remember:

View > Canvas Settings > Opacity: 0%

That's all there is to it!
