I'm a long-time ViewPoint user, and make use of the version built into PhotoLab with every image. I suspect I'll be using the ReShape tool much more than I first thought! Looking at the uncorrected vs corrected corners:īottom left corner, original and stretched ![]() A wider, fully corrected image, with no vignetting, and no cropping needed. They avoid the vignetted corners by unnecessarily heavy cropping, producing a much narrower image.Ĭorrected in PL6 using the ReShape tool from VP4. This is the significantly narrower view that an OOC JPEG or most raw processors (eg, ACR, C1) would produce. ![]() Here's an image with such vignetting on the left side, because of a very slightly decentred lens This vignetting is only apparent because DxO gives a wider corrected image than most raw developers like ACR or C1): But the new stretching feature in VP4 gives another, easier way that can yield pretty good results. There are various ways of dealing with this: crop the dark corner off (works, but you lose image area), clone nearby areas over it (works, but a bit tedious) or try to lighten it with a graduated filter (easy, but doesn't usually work very well). This is particularly the case if the lens is decentred, and most are. But this sometimes means you get vignetted corners at the wide end of compact zooms, where the image circle doesn't quite cover the sensor. ![]() DxO is good at maximising the image size that it extracts from a raw file, much better than Adobe or C1. Here's another variant of that type of fix. Hey, that's cool, and something I'm going to try next time I have a similar perspective correction issue.
