    I would like to crop and enlarge a section of a digital image to 11x14.
    The original file is a canon raw file Made with a 10D. The file is
    2048x3072 aprox.(6.75x10.75).

    I would like to know how to use Photshop CS2 and Genuine Fractals 4.1
    to do this.
    I am confused with the order of doing things with GF 4.1.

    How do I get a specific size crop with GF?
    Do I need to upscale the whole image first with GF and then crop with
    PS or GF??

    thanks in advance.

    At what ppi?
    What I'd do is use either the Crop tool or the Rectangular Marquee tool
    with Style : Fixed Aspect Ratio set to 11x14 to crop to the correct
    aspect ratio and then save this with a new name. Then you can resize
    it in Photoshop with Image - Image Size with resample on, plugging in
    the ppi and using bicubic smoother.

    I haven't used GF 4.1 but on the earlier version you would do a File -
    Save As and pick .stn as the file type and that would open up the GF
    dialog box and you'd save it as a .stn file, then when you opened the
    ..stn file you would have the option of defining the exact size you
    wanted it upsampled to. I don't know how different GF 4.1 is, I hear
    they may have changed it a lot.

    At any rate I'd try it both ways and if GF 4.1 is like the earlier GF I
    have I'd bet the Photoshop resampling will actually look better ... but
    try it both ways if you have GF and compare.
    I don't think you can crop with it, just resize?
    You can do it either way, ie like I suggested (crop to the correct
    aspect ratio first and then resample) or you can upsample first at 3:2
    and then crop to 11:14 but to me it makes more sense to get the aspect
    ratio correct first ...

    1) Crop the image.
    2) Save as an STN file with GF.
    3) Open said file, increasing the size by ten percent.
    4) Repeat steps 2 and 3 until you have the right size file.

    You no longer have to save the file first as an .stn before GF
    operates on it. You just open GF on the file your are working on and
    scale it right from there.

    Sorry I'm still a little confused. If I use the crop tool in PS preset
    to 11x14, and crop a section of the image to that size, then when, why,
    and how would I use GF. Since the image would already be the desired

    If I can crop straight from GF plugin, how do I get a 11x14 image from
    a smaller than 11x14 image?

    GF works better if you scale a file up by 10-20 percent at a time rather
    than going right to a 500 percent boost.

    It's the desired aspect ratio after the crop but maybe not the "desired
    size". He's starting with a 3072 x 2048 pixel image so 3:2 aspect
    ratio ... crop it to 11x14 and the max you have is about 2607 x 2048
    pixels ... you CAN print this 11x14" but it's only 186 pixels/inch,
    which is probably not enough resolution for a good print. The printer
    driver will upsample this for you or you can upsample it yourself and
    doing that upsampling is where GF comes in.

    Exactly HOW you use GF depends on the version. On the older version I
    have you just save this 2607x2048 file as a .stn and when you open the
    ..stn you get the option to resize. For newer versions see Scott's
