Digital photographers like to say that correcting shooting defects with
software is bad practice, the equivalent of compensating for a flawed
negative in the darkroom. These programs make us beg to differ.
Interpolation-the process of adding pixels to an image so you can view or print it bigger-should be handled with care. Using Photoshop's Image Size dialog and its default bicubic resampling sometimes works fine, but quality can suffer if you try to go too big. The latest version of Genuine Fractals' popular plug-in, which is accessed through Photoshop CS, CS2, or Elements 3 and 4, is simple: Open it, input the new image size you want, check the preview, crop if you like, and hit OK. We got better results from the software than we did with the same amount of upsizing in Photoshop. And because Genuine Fractals is a plug-in, you can create a Photoshop Action to enlarge in batches. About $160.
