Anyone have any idea if photoshop has capabilities or if there is a plugin available for enhancing the resolution of a photo? Is it even possible to do such a thing? For some reaon I seem to recall there being a util or something out there that can do it. Any suggestions?

I remember something that worked along the principle of using fractals to increase image resolution, but that it was horribly expensive. Can't quite remember the name. Does that sound familiar?

well doesn't really sound familiar but thanx for the response. I'll take that information and see what I can find.

There are a number of plugins that are designed to increase the resolution and/or size of an image cleanly. I use Stair Interpolation by Fred Miranda, which is a Photoshop Action and very, very reasonably priced. If you have more to spend, there's also Genuine Fractals, Qimage's Lanczos, and S-Spline, but I don't know much about the latter two. I have used the Genuine Fractals plugin and it's very good, but quite pricey. More information on Stair Interpolation via the attached link, including visual comparisons to enlargements and enhancements done with other plugins. bonni

odd, you would think photoshop would have it built in, just like photopaint does. oh, yeah it does but it doesn't do that good a job. try in the photoshop forum, you might get much more help.

My recollection of people talking about Genuine Fractals is that they usually say it's not much better than Photoshop's bicubic interpolation.

I've tried the above products (and methods) mentioned above but found Genuine Fractals PrintPro the best at what it does (been using it for several years now). What it does is increase (or decrease)the resolution (number of pixels)with the least amount of quality loss. Note:There is always going to be some quality loss when you increase or decrease the resolution size with any method. However I'm not sure if this is what you are looking for as you said "enhancement". You may be thinking of increasing the apparent sharpness of your photo. If this is the case,try using the "un-sharp mask" found in Photoshops filters. This usually is good enough for most needs. However if you need the ultimate control in what,how much,and what method is used to sharpen (plus getting rid of the unwanted artifacts caused by sharping),the plugin called "FocalBlade" is what you want (link).

It's also worth checking out the free Irfanview , it contains some useful resampling filters such as Lanczos.

Another Photoshop plug-in you may want to try is ResizeIT by OutdoorGrace. There is a usage-limited evaluation available from the attached link above. Im very impressed with this plug-ins capabilities.
