I’ve noticed odd behavior with the drop shadow before, but this latest one is a problem for me.

I start with an image containing a layer with a drop shadow falling onto the background layer. I enlarge the canvas (Image > Canvas Size) from 1000 pixels to 1001 pixels, and the drop shadow grows by a factor of 7-8 times. What’s going on and how do I prevent it without flattening the image?

Frequently, odd behavior of layer effects occurs when you are not working at 100% magnification. Often the problem is solved if you view at 100%.

If this isn’t your situation I would next wonder whether your video drivers are the most current for your hardware.

Thanks for your reply.

If I understand, you’re suggesting the effect is an illusion — not actually happening. When I save the file and later reload it, the very much too wide shadow is still there. Do you agree this eliminates possibility of an illusion?

IN 7 and earlier you have to scale effects manually, Layer>Layer Styles>Scale Effects. In CS I believe there is a checkbox in the Layer Styles dialog that allows it to happen automatically or not.

Well, if the problem involves video drivers or magnification and you’re simply saving and reloading using the same magnification and same video drivers then, no, I’m not sure it proves anything. If you print the file before you increase canvas size by one pixel, then print the new version, do they print as they appear on-screen?

There might indeed be a problem other than those I suggested, but I’ve been unable to reproduce the problem here so it’s pretty difficult to diagnose.

I haven’t printed one but I have saved a flattened image as jpg and the jpg has the deformed shadow when viewed in IrfanView.
