First thoughts on Straighten
We were delighted to see the arrival of the Straighten button in version 2.10.4, mainly due to our inability to hold a camera straight. Version 2.10.6 extends this handy feature to include vertical straightening...
First thought was that I wished I'd had that when I was scanning about 10,000 old family photos that came down to me. I would do several in one scan, then, using GIMP 2.8, cut out each individual one, and nearly always had to rotate them a little because it's impossible to place them exactly on the scanner platen.
But I have just tried the new "straighten" function, and I think that hitting shift-r and rotating the image manually is probably quicker. And not every photo has a handy vertical or horizontal straight line.
Still, I'll give it a proper trial when I come to scan the thousands of my own photos, which SWMBO wants out of that cupboard!
