Upsizing, with current technology, is one of the thorniest tasks you can perform on an image. Photoshop can upsize your image to a limited degree without loss of too much quality, but there are numerous other specialised apps which have tried (and many have failed) to improve on Adobe’s upsizing formula. One of them, PhotoZoom Pro 4, I have already reviewed, but this review is dedicated to a competitor – AKVIS Magnifier.
AKVIS isn’t hugely pretty, but the layout of the controls within the app is sensible and clear. Your opened picture is displayed on the left, while the upsizing and adjustment tools are in a column on the right (think Lightroom). You can have one of two set-ups – express or advanced. The express set-up reduces the displayed controls to size/ppi and edge sharpness/artefact removal, whilst the advanced set-up adds sliders controlling grain, ”simplicity” (how much you want to smooth out pixelation) and edge smoothness. In the advanced set-up, there is also the option to use Unsharp Mask, but, to be honest, the last time you’d want to be sharpening your image is when you’ve just upsized it – if you use this control, watch out for jagged edges coming at you from out of the screen.
By using AKVIS’ presets, and then applying little tweaks to the controls here and there, you can get quite a usable picture, even when you upscale by 500%. Don’t get me wrong – the quality is significantly degraded, and I don’t recommend you try this stunt. For something to hang on your wall, however, the picture AKVIS produces is probably acceptable.
