Straightning a Crooked Photo, some help please

[leon]

Good afternoon, some time ago a person called H from here explained to me how to straighten a photo that is slightly crooked, and because i am old and forgetful I have forgotten how to do this.:sadeyes:

Maybe some one here could help please, I am using Digital Photo Professional:)


Thank you :thumbsup:

Hi Leon - look for a 'rotate' option in the tools section...its been a while since ive used DPP, but thats where/how it can be done.

DPP is great, but i use irfanview as it is much simpler and intuitive to use, and with the right plugins reads canon RAW just fine...

Thank you for your response I will give it a try.

In GIMP it's Image -> Transform -> Arbitrary Rotation. Try a rotation. If it's not right undo the action (Ctl + Z normally works) and try a different value. I think that is better than doing several rotations to arrive at the correct value. Each rotation involves interpolation and it sounds wrong to interpolate on interpolations - the errors must multiply.
