How many times have you gotten a photo that just doesn’t have enough resolution/pixels for the project at hand? Sometimes this problem can be resolved by finding an original copy of the image that has more pixels. Even then, it still might not be enough.
Yes, popular image editors have the ability to upsample images. To increase the size just a little bit, that might work just fine. But if you really need to enlarge the image, you might want to look into a product like the just-released PhotoZoom Pro 3. It was designed for upsampling images with their patented S-Spline technology that provides a much-higher quality than what you find in image editors. The latest version of S-Spline is the S-Spline Max found in this new version.
In addition, there is now support for multi-processors so that images can be processed much quicker than in previous versions. You can run PhotoZoom Pro 3 as a standalone or you can use it as a plug-in with image editors that support Photoshop automation and export plug-ins. While I have not yet tried the new version, previous versions worked great with Corel PHOTO-PAINT X4.
A product like this is especially useful for those outputting large prints or signs. But it can also come in handy if you have a fairly low-resolution original that simply isn’t good enough. I’ve had great results with the previous versions and I’m anxious to get a copy of this new release.
