Sigma attempts to fix green corner vignetting in DP-1

http://www.dpreview.com/news/0804/08...gmaupdates.asp Well, I've got plenty of shots on a DP-1 without any green corner vignetting. Having said that, I have used it for what it does best - very sharp pix at f8 in good conditions at ISO 100. But even rubbishy snaps taken inside aircraft, at night in cafes etc, have not had green corners. I have just been running 20+ final selected DP-1 pix through an action to correct the small of CA present. It needs +8 Red/Cyan in the Photoshop 'Distortion' menu Lens Correction filter, when exported to 53.5 megabyte double size (18 megapixel) files via Sigma Photo Pro 3.1. David |
