how to blend edges of adjacent photos?

I want to put two photos side-by-side and have the edges blended so that there is no sharp boundary but rather a gradual transition from one photo to another.

The only way I know is to select a small part of the edge of each photo, feather the selection, delete the selection – this gives each photo a "faded edge" – and then copy and paste the photos next to each other with some overlap.

This is tedious and hard to adjust the amount of overlap. Is there a faster way to do this?

Which version?

CS and above, File>Automate>Photomerge.

Or use Layer Masks. Never erase or delete when you don’t need to.

Thanks. I tried both suggestions. I have CS2.
Don’t like the photomerge. It seems to do more than I want.

The layer mask method works better than my first method. But it is hard to adjust the amount of overlap.

Perhaps I should start with a simpler question: how do you create a feathered selection that goes from 0% selected to 100% selected over a 10-pixel wide strip at the right edge of a photo? This photo has been shrunk after imported, so there is a lot of transparent space around it.

The method I use is to drag a rectangular selection much wider than 10-pixel and a lot taller than the photo and place this selection so that a 10 pixel strip of the photo is in the selection. Then feather it with 10 pixel.

The problem: I don’t know how to precisely place it so that 10 pixel of the photo is in the selection, other than zooming in and counting off 10 pixels. If I want a 100 pixel strip, it would be hard to count.

There are so many ways approach your task. One way is to use ‘Styles’ using stroke and a radial gradient.
Another is to make a selection using one of the selection tools then ‘feather’. Then use that feathered selection to make a mask that you Gaussian blur with a pretty high radius – say 45.
Another is to just Gaussian blur a channel and use it as a mask – these masks make good starting points.

Good luck,
Ron

Btw, try softening your brush and changing rate if you are having trouble adjusting overlap with masks.

Yes. Learn to use layer masks.

Something that will help you in the future: NEVER delete part of a layer. Ever. When you do, it’s a one-way trip–you can not go back. Instead, use a layer mask to hide the part of the layer you want to delete. You can always bring it back later if you change your mind.

Make a selection, feather the selection, then use the Select->Save Selection command to make the selection into a layer mask.
