PhotoZoom Pro 4 review
PhotoZoom Pro 4 features a resizing entry for pixels and percentages and another for showing the print size at a specific dpi. There’s just one preview window, which updates slowly as the new size is input. It offers a large choice of resizing methods, but no real explanation of the differences between them.
The Presets lists cover photos, graphics, downsizing and reducing JPEG artefacts in images. There’s no specific option for portraits or low-res sources, but the Photo-Detailed option tries to enhance details while Photo-Soft doesn’t. There are functions for unsharp mask sharpening and fine-tuning with film grain, artefact reduction and edge sharpness.
The artefact reduction system is ideally suited to enlarging low-res portraits
In our low-res portrait test PhotoZoom Pro 4 produced the best result here, producing a good combination of artefact reduction, detail and edge smoothing. It wasn’t as good on the noisy, high-res landscape, though, with a little jagged edge and more noise.
