    Hi,

    there has been an "urban myth" ging about that if you magnify the size
    of an image in photoshop by 1%, and do it 100 times, that it will
    interpolate up the file, but keep a lot of thedetail.

    Well I have tried this, and made it into an action, and it actualy works...

    BUT I have foundthat you must use the 'Bicubic Smoother' in Photoshop CS
    and CS2, ifyou use the bicubic (plain) then you get tons of Jpeg
    (oversharpening) type artifacts...

    I have tried Extensis PxlScale, and that works great also.

    any one tred any other Photoshop urban myths.

    regards

    Sandy

    Hi Sandy,

    did you compare it with doing it in one go?

    I read somewhere that a good way to enlarge an image
    is to change the mode to Lab, select the lightness channel,
    and enlarge in 10% steps. I tried it out -- and also tried enlarging
    in one step. I put the results side by side onscreen and if there
    was any difference it was too insignificant for my eyes to pick up.

    I thought that it was a sharpning technique, that you did in the L channel
    of LAB mode. to avoid halo's when applying USM, I haven't tried scaling in
    LAB

    thanks
