Thanks Herschel, 

Tried those too, and yes, still getting wonky images. Ah well, there was me thinking photoshop could do almost anything! 

Cheers

You asked if there was an easy way... not really... but the liquify tool is available and... The "WARP" command... EDIT > TRANSFORM > WARP.... You can choose the tool options.But whatever you do you're going to get distortion on the page.

    Thanks James, 

    unfortunately, they are too big (and very old) for that, which is
      why I've been using a copy set up with lights and camera. 

    Surely PS must have something which will convert a selection into
      straight lines? Or align a selection with a rectangular marquee? 

    Cheers

        I use a ScanSnap SV600 scanner for that

          the surface, scan, and then the built-in software makes the
          corrections to compensate for distortion made by the arched
          pages.
        I haven’t checked for sure but I think I
          get 600 DPI directly in whatever size the image is.  
        The platform is about 16x20 inches or so.

            Subject:  Transform question

        Hi folks,

        I have a question, and wondered if any of
          you may have an answer;

        I've been photographing some paintings,
          bound in large leather volumes. 
        The volumes are thick, so that some of the
          paintings don't sit flat - 
        there is curvature along the long and short
          edges. So, question is, is 
        there a simple way to correct the page
          distortion back into the 
        rectangle that it should be...?

        I've tried selecting the paintings, and
          using all the various transform 
        tools in Photoshop, but there are still
          curves and bends which I can't 
        straighten out. Even had a go with puppet
          warp, with some limited 
        success, but still ends up with wavy lines,
          not straight edges.

        With all the amazing tools PS has I find it
          kind of hard to believe that 
        there isn't an easy way to select a shape
          and transform it into a 
        rectangle...or just turn a bent edge into a
          straight one?

        All suggestions welcome. Thanks

        Jonathan
