Hi,
I’m relatively new to Photoshop, and my situation is this:

I have stills that I captured from a security camera VHS tape. I would like to zoom in on the person on the tape but when I do the image becomes heavily pixelated. Changing the resolution helps a bit, but not nearly enough to make them recognizable. The image is grainy to begin with. Any suggestions or how-to’s would be appreciated…

thnx

That only works in the movies. I doubt that you will be able to zoom in and get a recognizable image.

You need pattern recognition software and access to the national database. See, they never really see the object’s face, just a pattern something like the one you see when you blow it up. What you see is what you get.

"Can you zoom in on that 640×480 still from my $20 digital camera with no zoom?"
"Sure!" <Zooms 100x closer> "Enhance. Enhance. Enhance. Okay, the microfiche reads: "…….." "

Only in the movies… 🙂

If you have more than one sequential frame where the subject is not moving, average them (more is better). Averaging will remove random noise and reveal stationary features.

Averaging can be done with Image|Apply image… , or by layering multiple layers with appropriate (for the number of frames) opacity.

Try any of the "stacker" programs on individual frames. The astro shooters use these stacker programs to enhance VERY weak stuff. They are not trying to reproduce a face however.

I’ll bet it would work though.

Go here: http://www.tawbaware.com/imgstack.htm

Or here: http://www.unm.edu/~keithw/keithsImageStacker.html

Or here: http://68.113.85.217/image_stacker.htm

Or any of the other sites that specialize in this stuff.
