I found a messsage in the archive asking about this, but it was unanswered.

When I bring an image into Photoshop CS2, duplicate the Background layer and then crop the image (setting width, height and with or without settign the resolution), I end up with an image of correct size, but the edge (a pixel or so) seems to be semi-transparent. Interestingly, the original Background layer is fine. I’ve tried all sorts of Resample and Tranparency settings, but nothing eliminates the "feathered" edge. Any ideas? I must be missing something.

Are you quite certain that the crop settings (or the resample settings) are to integer pixel values? Cropping a picture to an origin or a width/height that’s not an integer pixel value can cause problems like you are talking about.

Thanks, Michael, but I’m pretty sure everything is set to pixels, and I’m only using whole numbers. I even tried changing the Pixel/Pica settings in General Preferences, but it didn’t change the outcome.

Try setting the crop tool to ‘hide’ and not ‘delete’

Excellent, CN! I’ve never used that feature before. (Honestly, I didn’t know what it did until now.) I should add that Hiding the cropped area yields great edges only if I don’t use any of the original image’s edges as a starting point. In other words, I still get the semi-transparent edge(s) unless I nudge the Crop mask in a couple pixels from any edge.

I haven’t installed CS3 Beta (yet). I’ll be purchasing the upgrade soon enough and I hope this quirky behavior (maybe it’s only my machine) doesn’t exist. I find that it’s very useful to take a higher resolution image and use the Crop tool to set the Width, Height and 72 ppi resolution. It makes me wonder how many images I’ve uploaded prior to noticing the semi-transparent edges…

Thanks again for this idea!

Cybernetic Nomad, or anyone else, the Hide versus Delete was a fine workaround as I mentioned for cropping, but now I’ve discovered that it happens when I resize any image whether or not I change the resolution. I’ve been reading about partial pixels, but I don’t understand that. Why would resizing an image (including cropping) create a feathered edge?

I’m not a master at Photoshop, but I’ve been using it since version 3 or so and I’ve never experienced this issue before. I must be missing a basic concept somewhere along the line.

I want to repeat one thing…this only happens when I reduce or crop a layer. I typically duplicate the Background layer when brining an image into Photoshop and then work on the Background Copy. This allows me to work with transparency and the original image is psuedo archived as the disabled Background layer. If I disable the Background Copy, turn on the Background and resize the image it turns out correctly (without the feathered edge).

Thanks.

We were playing around with this and if you flatten the image so you layer is "Background" the feathered edge does not occur when you resize.

this is an ok work around for some purposes.
