    Is there a way to BULK CROP photos NOT BULK RESIZE but BULK CROP?

    I am in desperate need of BULK CROPPING some photos with detailed directions

    I have over 20,000 scans that were done.
    There is a large amount of "DEAD BLACK" space on the photos.
    I am wishing to CROP the photos without doing them one by one.

    I am having a difficult time figuring out how to BULK CROPPING photos.
    Can anyone help me?
    Thanks in advance.

    I am NOT interested in BULK RESIZING my photos.
    I am interested in BULK CROPPING photos that were scanned.
    I am trying to get the BLACK dead space off of thousands of scans.

    I have about 10,000 scans that need to be cropped all the same DIMENSIONS.
    Does anyone out there know of a software program that can crop many at a
    time instead of manually?

    I have been told that
    "I'd use Photoshop. In this program you can make a so called 'Action': a
    series of handlings, applied on one image, that you can save a Action. Later
    you can use those Actions in a batch process. Perhaps you can get an old
    version. To my knowledge the batch-option is abled from version 5."

    Is this true?
    If so please advise and thanks.

    I simply do not have the time to crop one by one 20,000+ scans.

    If someone knows how to do this, can they please email me, thanks again!

  2. Yes, you can do that in Photoshop. You need to use 'Canvas Size' to crop
    an image. Determine what the canvas size of a cropped photo should be,
    record it in an action and then use that action on the folder of scans
    by means of 'Automate - Batch'. That's all.

  3. I forgot: If the photos are not all the same format and/or the same
    orientation, you can still use 'Canvas Size', but then you need to use
    it with 'Relative' checked. Let's say you want to remove 10 pixels from
    each side, then you use -20 pixels height and -20 pixels width, with
    Relative checked.

    There is another option if you use Photoshop CS*
    File - Automate - Crop and Straighten Photos
    Using this method the picture can be anywhere on the scan and could be
    included in your action.

    If the black part is the same on all of them, then you can do it as a
    batch. If it's not, then you'll have to manuall crop them.

    If I had 20,000 scans to crop, and they all required the same crop, then
    I'd use ImageMagick's mogrify command. (Cuz that's pretty much exactly
    what it was designed to do.)

    In Photoshop, you could set up an action that somehow used the magic
    wand to select the top-left-most pixel, inverted the selection, and then
    did a crop. Then run that 20,000 times. :)

    This response is late, but here goes.

    If you can use the same crop rectangle location for all the images, or if
    you can sort the images into several groups that each require the same crop,
    the following procedure may work:

    1) create a new action and record the crop for one image.
    2) use Photoshop's batch command, or create a droplet to apply the action to
    all of the images.

    As Paul suggests, if the crop varies- as it would be for example with
    scanned vertical and horizontal slides - you can use the magic wand tool to
    select a black portion of the image and do a crop based on that. In that
    case, the magic wand location must be the same for each image.

    Actions are prone to failure at some point for large numbers of images. I'd
    split the images into folders and do a few hundred at a time, rather than
    tackle all 20,000 of them at once.
