How do you get a degredated border?
Jon from Australia, using Photoshop 6 with WIN XP Pro, writes in with:
[Quote:] I really like this image on the Starbucks web site (especially the "Pike Place Market and the espresso images) What I have tried to emulate is the eaten away border of the image. I also noticed that the holes in the images are identical. This got me to thinking that the degeradation of the image is some how a screen that is in a higher layer. I approached the manipulation of my image by using the airbrush. I set it to a grungey brush downloaded from the net and tried painting the lines in. However what I struck was a step and repeat pattern from the brush that didn't have the randomness of the image that Starbucks have used. The next issue I had was that I had not used a transparent background on the image. When it was placed the holes that were left by the brush showed up as white. I then tried to use the magic wand to select it all, but the bruch strokes were too complex for the wand to pick up easily. I am not too sure where to go from here. Would greatly appreciate your insights.
Ahhhh.... it's the old border mask trick. No, you won't be needing any brushes. It's much simpler than that. The 'uniformity' between images is telling you that they used the very same layer mask for all the images.
Try this: Open the file you wish to generate a frame for. Select all (ctrl/A), and choose File > New File. The new file dialog should open pre-set to the size of the open file. Add enough extra pixels to provide room for your frame. Drag your image into that file using the Move tool.
Use any of the selection tools to create the basic shape you want for your edge treatement (frame.)
See: frame selection picture
With the selection active, click Add Layer Mask button at the bottome of the Layers Palette. (Round circle with dotted-line border.)
See: Layer Mask Applied
With the layer mask selected (double borders on the mask in the layers palette) choose Filter > Blur > Guassian Blur and set to an appropriate radius.
See: Layer Mask Blurred
This will introduce grayscale pixels into the mask.
Now, applie what ever artistic filter you wish to the mask. Here, you see we've use the "Rough Pastel" filter.
See: Filter: Rough Pastel sample
The results of that filter applied to the image would appear to now frame the image
Once your frame is the way you like it, you can begin dragging new images into the same file on their own layers. (Use the Move Tool to merely drag the new image into the file.)
Now, click the little chain link between the layer mask and the actual layer thumbnail, to release their relationship.
Then Command-click (ctrl/click) on the layer mask we previously created, (which makes an active selection from the mask) and then select the layer for the new image.
See: Selected Mask
With the new image layer selected, click the Layer Mask button at the bottom of the Layers Palette and voila... this new picture now has the same border / frame.

If you're doing a series of these, make sure they're all the same size, and just keep adding.
Remember the key issues:
* The frame is custom sized to fit your picture
* The initial selection governs the shape of the opening
* The amount of blurring governs the amount of frame
* the filter gives texture, use any filter you like
* The layer mask becomes a channel that can be applied to any other image.
