    Scott Kelby technique for upsizing images

    Found this technique Photoshop by guru Scott Kelby on another forum. He uses it to upsize his photos with Photoshop.

    Since many Ragers also use Photoshop I thought some of you maybe interested in this tip....

    This is an excerpt from Scott Kelby's "The Photoshop CS2 book for
    digital photographers"

    Rule-Breaking Resizing for Poster-Sized Prints

    This is a resizing technique I learned from my friend (and
    world-famous nature photographer) Vincent Versace. His poster-sized
    prints (24x36") always look so sharp and crisp but we're both shooting
    with the same 6-megapixel camera so I had to ask him his secret. I
    figured he was using some scaling plug-in, but he said he does the
    whole thing in Photoshop. My thanks to Vinny for sharing his simple,
    yet brilliant technique with me, so I could share it with you.

    Step One
    Open the photo you want to resize, then go under the Image menu and
    choose Image Size. By the way, in Photoshop CS2 there's now finally a
    keyboard shortcut to get to the Image Size dialog: Command-Option-I
    (PC: Control-Alt-I).

    Step Two
    Type in the dimensions you want as your final print size. My original
    width for my 6-megapixel image is just a hair over 10", so when I type
    36" for the Width, the Height field will automatically adjust to
    around 24" (the Width and Height are linked proportionally by default
    adjust one and the other adjusts in kind). Of course, not all images
    scale perfectly, so depending on how many megapixels your camera is,
    you may not be able to get exactly 24" (and in fact, you may not want
    to go that big, but if you do, you might need to enter more than 36"
    to make your Height reach 24", and then you can go back and crop your
    Width down to 36" [see the "Cropping to a Specific Size" technique
    earlier in this chapter]).

    Step Three
    Once your size is in place, you'll need to adjust your resolution
    upward, so go to the Resolution field and enter 360. Now, you know and
    I know that this goes against every tried-and-true rule of resolution,
    and breaks the "never-just-type-in-a-higher-number-with-the-Resample-Image-checkbox-turned-on"
    rule that we all live and die by, but stick with me on this one you've
    got to try it to believe it. So, type it in, grit your teeth, but
    don't click OK yet.

    Step Four
    Back in Photoshop CS, Adobe introduced some new sampling algorithms
    for resizing images, and according to Vincent's research, the key to
    this resizing technique is to not use the sampling method Adobe
    recommends (which is Bicubic Smooth), and instead to choose Bicubic
    Sharper in the Resample Image pop-up menu, which actually provides
    better results so much so that Vincent claims that the printed results
    are not only just as good, but perhaps better than those produced by
    the expensive, fancy-schmancy upsizing plug-ins.

    Step Five
    I've tried this technique numerous times, and I have to say the
    results are pretty stunning. But don't take my word for it click OK,
    print it out, and see for yourself. Here's the final image resized to
    36x24" (you can see the size in the rulers by pressing Command-R [PC:
    Control-R]).
