how do i add the bird in a cage?i don't see how a mask would help in this instance.
Yes, a masks helps a lot... because you have to make transparent all that background between the bars.
I'll assume you have a nicely cut out bird (ie, bird surrounded by transparency). Otherwise, you'll find plenty of tutorials for that.
What we will be doing is stack:
- cage image in the bac,
- the bird
- the bars of the cage that should appear in the front
At that point the first two are already done. So, to get the front bars and remove the rest, we will take advantage of the fact that the cage is an almost perfect white and that's the only white thing... so:
- duplicate the cage layer, and move the duplicate to the top
- Layer/Transparency/Add layer mask, and initialize the mask with the grayscale copy of the layer.
- At that point you are already in layer edition mode
- Colors/Threshold and use a high threshold (looking at the histogram, you'll see that you can pick any value between 175 and 240). This make everything in the image disappear, except
the cage bars.
- Apply the layer mask
- The delicate part of the process: you have to remove in that layer the bars in the back that should be hidden by the bird.
- To make sure you erase only where necessary, make a selection on the bird: select the bird layer, and Layer/Transparency/Alpha to selection
- Remove the bars in the back from the top layer with the eraser, that will act only within the bird shape.
Done.
