Hello again Rosemary,
Yes, I've given it a whirl on one or two JPEGs and it does seem pretty good even in automatic mode. The file size seems to increase quite a bit but I see no aberrations in the pictures at all.
Definitely worth considering for correcting those verticals! So - thanks for this!
P.S. I must confess to not having viewed the "Tips and Techniques" part of the forum very much but I can see that it might be very useful.
There's a program (really a Photoshop plug-in) which I have been using for ages called "Smart Curve" from "Easy Filter" - another free download. You can plug it into any version of Photohop Elements and it provides you with a very useful "Curve Tool" - something which is sadly missing from Elements. It might be useful for those who cannot afford the full-blown version of Photoshop and so I might post something about that later on this forum. Do you think that would be a good idea?
