View Full Version : Remove blur from out of focus camera
12-27-2005, 12:47 PM
I am trying to perform some image restoration on an out of focus image that is the result of a camera out of focus. What is the best way to do this? I'm playing around with Unsharp Mask but am not having a great deal of luck.

Sorry mate. It cant be done.
The principle is this: blur = loss of imformation. Photoshop cant invent that information.
There are various plugins and techniques (mostly involving unsharp masking) that claim to be able to go some way.... but I have never seen a satisfactory result. Unless anyone out there knows different?

... jup this is practical not posible... you can sharpen it in few different ways, but i guess the result will never satisfy you ... as Jack said, information which the camara dont caught cant be recreated with a computer progam ;)

Thanks for your input. I thought that might be the case - I have *improved* the image with Unsharp Mask but I suppose there is only so much you can do.
Just to clarify - if you have a single image is Unsharp Mask the best way to do it? I have seen there is a new Smart Sharpen feature on CS2 - is this any better?

dont know about smart sharpen (no cs2 yet ;)).
best way = a mix of unsharp mask and blending original image with adjusted one. Cant remember how exactly.... just play and see.

Yup. It is basically U.M. with parameters you can change, in highlights/shadows area and removal of gausian/motion blur.http://i23.photobucket.com/albums/b378/evanfotis/Pictures/smartsharpen.jpg
post the picture you're trying to fix. I mean it's true that you can't "make-up" information, but you can take nearby colors to complete your image. Again, this is situation specific, would need to see the pic first.
