    hi all!

    i have a photo with a white background and i would like to crop aorund
    the edges smoothly (important!) leaving a white space of about 5mm
    around the edges, how can i do this in photoshop? i can only find
    cropping tools for predefined shapes.

    kind regards

    Use the magnetic lasso tool first. then smooth out the outline using the
    ordinary lasso. Finally use expand selection to create the border.

    Hey Stewy thanks for help

    Can you expand upon what you mean by "smoothing out the outline "by
    using the ordinary lasso"?

    regards

    Question: is your subject image on a white background, all of the way around
    it? If so, use the Magic Wand Tool, to select the white area. You may need to
    experiment with the tolerance setting, but if you have white, start with a
    lower # and work up a bit at a time. You can also press Ctrl, as you do more
    selecitons, if you are missing a few to add to the Selection. Once you have
    the background selected, Save Selection (name it something like "Outline."),
    then choose Select>Modify>Contract, again experimenting with the # of pixels,
    as there is not a direct way to specify 5mm, but you could hit Ctrl-R to get
    the rulers, set units to mm, then do some guides to indicate 5mm from the
    subject in one spot, and match that, as you explore the Contract setting. Save
    new Selection as something different, i.e. "Outline 5mm."

    This will allow you to knockout the subject, but remember to actually Crop the
    image, you can only Crop in a Square or a Rectangle. You can Ctrl-c (Copy)
    this outlined with 5mm white and drop into another image, or use the Selection
    as a Clipping Path and do a GIF for the Web or an EPS for use in PageMaker/
    InDesign/Quark.

    The easiest way to go about this would be to use the Crop Tool and crop
    your image to the desired size. The next thing to do is go to
    Image->Canvas Size. Click the "Relative" check box and set your size to
    10mm for both the width and height. This will give you a 5mm border
    around your image.

    First of all "Crop" is the wrong term. What you want to do is make a
    good selection around the object and delete or mask out the background.
    Best way, though not easy, is with the Pen. Another possibility is the
    Extract filter. There are other ways.

    Here's a tutorial (there are many on the web). You don't need to make it
    an actual Clipping Path unless you are putting it into another program
    like Quark. You can turn the path into a selection and make a mask with
    that. You can also stroke the path or the selection to get your white
    outline.

    I suppose that "Crop" would be the wrong term if knocking out
    everything, but a specific subject matter. However the way that I have
    understood the dilemma is that a "Crop" is needed. Besides what in the
    world would compel you to utilize a (ahem) multi-page program like
    (ahem) Quark (pronouced Quack) to knockout an image. Illustrator would
    be my first bet. Not a piece of software designed for books and
    catalogs. You don't need to turn the path into a selection to create a
    Layer Mask, you can use the path to create a Vector Mask which is much
    cleaner...unless you wanted to apply filters, adjustments, or hand
    paint the mask.

    edjh: Maybe clarification of the issue at hand is needed?

    Enjoy...

    Thanks for everyones comments here its been really informative. However
    with regard to smoothing the outline, what im looking for is photoshops
    equivalent to flash's "soften fill edges" tool, is there one? (ive
    tried anti-aliasing and feathering to no avail)

    Thanks

    Cropping is a different thing entirely. If you want to make the image
    area smaller a crop might be in order, however that has nothing to do
    with taking an image out of a background.

    Besides what in the
    You misunderstand. The tutorial I linked called for making a Clipping
    Path out of the Path. My point is that you don't need to make it a
    Clipping Path unless you are putting it into Quark or something like
    that. A regular old Path will do. Make it into a selection to delete or
    mask.

    Illustrator would
    Yes, you do if you are making a Layer Mask.

    , you can use the path to create a Vector Mask which is much
    Vector masks are fine too, if no feathering or such is needed, which
    often is when isolating an image from the background. Hard edges can be
    undesirable if compositing the image into a new background for instance.
    Depends what he is doing with it.
