Subject: Re: How do you do this in Gimp now
If you are looking to do HDR i strongly suggest DarkTable heck i would
strongly suggest it for photography workflows in general. Gim is great for
some deeper manipulation, but for a Darkroom stype process Darktable is
fantastic. I would put it in a close contention to lightroom.
