The next set of images is res’ed up from 330 ppi to 360 ppi. With some resampling techniques, notably and egregiously nearest neighbor, resampling with resolutions that are close together yields obvious objectionable artifacts. As before, the results are followed by an analysis. Photoshop Bicubic Smoother (above) Perfect Resize (above) Qimage Hybrid (above) Qimage Fusion… [Read More]
