In Gimp 2.10, I have initiated a bank canvas. I press
R to use my rectangle tool to draw a rectangle. I then press
G to apply a gradient over my selection.
From this point, if I select none, the gradient no longer sits in my rectangle selection, but is applied to the entire image.
From this point, if I select Add Layer Mask, and then select none, the gradient effect that I used over my shape renames on my layer.
So my question is this...do I have to add a layer mask, whenever I want a gradient effect to take shape of my selection and stay on that layer? If not, what step was I missing?
