I cut out a piece of the stained glass onto a new layer and filled the rest with content aware. This texture and reference is all I used of the source image.
step 2 of 9
Remove color. This is the overlay to create the stained glass effect.
step 3 of 9
Acquire your desired photo and do what you will to it.
step 4 of 9
Filters/Noise/Median
step 5 of 9
Get large, similar color/content chunks onto separate layers. Keep a small amount of space between them.
step 6 of 9
Add a black layer behind all this. Use CTRL + U on each layer with colorize to make sure they are all solid colors.
step 7 of 9
Make a copy of the overlay layer for every piece of glass. Use layer masks to make them fit. Then unlock them and rotate.
step 8 of 9
Use color range to select the blacks in your source landscape, and copy to a new layer, fill with black. Use median to smooth it out a bit.
step 9 of 9
Use gradients to give it a bit of flair. I Copied the black layer from step 8 and filled it with 50% gray and added plastic wrap filter to five it a shine.
