adjusting a horizon

I know I have seen, in the Gimp Manual, a way of adjusting a photo that's been taken on a bit of a slant - for instance a photo of a window. I have a photo where my horizon is on a slant. Can anyone remind me where in the Gimp manual it tells me how to adjust this? many thanks for any help! Jude

Thanks Andre.I'll play with this feature. It's not the way of adjusting an image that I saw before - where there was a picture of a window. But I'm sure it will do the job. Many thanks.

this should be the first step in straightening out an image with distorted perspective, as you get when you don't hold the camera straight.

after getting _something_ straight, either the middle of the image, or an important part somewhere else, you'll have to adjust the perspective. either choose tools -> transform tools -> perspective, or the perspective tool from the toolbox.

you'll have to play around a little to find the ideal perspective shift. if you change the perspective too much, the photo will look weired. after adjusting the perspective you can undo & redo, and repeat the process if necessary.

online manual links:

http://docs.gimp.org/2.6/en/gimp-tool-rotate.html http://docs.gimp.org/2.6/en/gimp-tool-perspective.html

i didn't see a tutorial dealing with this subject, but you'll find lots of helpful information in there: http://gimp.org/tutorials/

Klaus Goelker's book GIMP 2 for Photographers has great information on this.

For all those tools mentioned in the other posts, check out the "Corrective" mode, preferrably with the transformation preview set to only "Grid". With that, it's just fun to correct skewed photographs.

Hello Phani,

check out the "Corrective" mode

please excuse my ignorance, but where do i find this mode?

http://docs.gimp.org/en/gimp-tools-transform.html#gimp-tool-transform -> Tool Options -> Direction

You find this setting (and all other tool related options) in the tool options dialog, which is a dock that is usually just below the tool dialog itself. If you can't find it, I suggest the chapters on docks & dialogs in the GIMP help pages.

I hope you enjoy it, Daniel
