»Hello good because when I change I make a new layer and I attach the layers changes the whole photo??? and it's not the first time it's happened«
I don’t understand.
The Layer »capa 4« has no Layer Mask so naturally it covers the underlying content.
which one do you mean this ???
I don’t understand what the problem is.
For example what do you mean by »acoplo las capas«?
Are you referring to the Layer Masks or to Clipping Masking or linking or …?
to turn them into a single layer
Could you please post screenshots taken at View > 100% with the pertinent Panels (Layers, Channels, Options Bar, …) visible?
And View > 100%.
What is this one screenshot supposed to demonstrate?
when you call 100% is zooming to 100% ???
