    use the eraser tool, and set your secondary color to white. zoom in and erase

    there's also the background erase tool, which is magnetic, but it doesn't always work. it's not always easy, and it'll take time.

    you can also trace the outline of it, cut and copy it to another layer, move that one below the background, and delete the old background, then start erasing whatever you missed.

    Increase the color depth to RGB, then duplicate the layer.
    then you can fill the background with white, and start removing black from your new layer.

    The question is hard to answer without seeing the image.

    Go to Select -> Color range in Photoshop
    Then click on th color you don't want and click OK. PS will select all of the color then click on delete.

    Upload the image, and I can give you a better solution.

    If you are using Photoshop then there is background eraser tool in the CS version that I currently use.

    There also a magic eraser both of them can do the trick.

    Thanks.

    In photoshop if you go to the select tab, then select color range and use the dropper to pick the color you want to remove and click ok it will highlight all the color that you want to remove.

    in photoshop, duplicate the layer (change to rgb if you have to)
    use quickmask and paint the section you want to keep
    switch back out of quickmask to have a selection of the image
    use layer mask to mask out the background
    This will give you an orginal on one layer, and a masked version on the other, turn off the visability of the orginal layer, and create a new layer with the background colour your desire.

    Sounds long winded?
    The aim is:
    1. not to destroy your orginal source material - you may need it again
    2. masks are easy to edit if need to add / remove something from the orginal

    When professionals silhouette an image, they do it manually by blowing it up a gazillion sizes and creating a manual path around the object. Time consuming but the results are terrific.

    It's a very time consuming process, but here is the best way to do it, with the best results. This is done using Photoshop CS2, will work in other versions as well.

    First: Dupliate the layer, then go over to your history panel and set a history point. This will become very handy here shortly.

    Now, on the duplicated layer, goto Filter - Extract. Basically with this tool you are creating a mask of sort around the image. Set the brush size so that is over laps onto the background by about 1/8 inch. I usually work with 20pt brush or so. If you have hair or grass you want to leave in you will need a larger brush to accomodate the wildness of the image. Now draw around your image making sure the brush is almost 1/2 on the image and 1/2 on the background. When your done get the paint bucket and fill the inside of the green line. Hit extract and your done, with this step at least. You will notice that your background is totally gone and some of your image is too, thats ok. We have the nifty history brush. Select your brush size, and choose the history brush. Now carefully use the history brush to redraw the missing parts. Make sure you release the mouse or pen often, as undoing an action may become very frequent here. In the end you will have a perfectly cutout image. This works awesome for things like hair, grass, and anything else that can take eons with the lasso tool and eraser brush.

    thanks for the tip.

    if you have the money though it's probably best to outsource it, this stuff can get very frustrating and the rewarding isn't super

    You can use pen tool or lasso tool or magic wand tool, make a selection, select inverse, and delete background
    Finish

    1. Start by opening an image that you want to remove the background from.
    2. Select the Background Eraser tool from the toolbox. It may be hidden beneath the Eraser tool.
    3. On the tool options bar at the top of the screen choose a round, hard brush. The size of the brush will vary depending on the image you’re working on. I’m working with quite a large image so I’ve picked a brush size of 100 pixels.

    Again, on the tool options bar, set the Sampling to Continuous, the limits to Find Edges and the Tolerance to a low number of about 25 20%. A low tolerance limits erasure to areas that are very similar to the sampled color. A high tolerance erases a broader range of colors
    4. Bring the pointer near to the edge of the person or object that you want to remove the background from. You will see a circle with small crosshairs in the center. The crosshairs show the “hotspot” and deletes that color wherever it appears inside the brush. It also performs color extraction at the edges of any foreground objects, so that color halos are not visible if the foreground object is later pasted into another image.
    5. Click and drag to start erasing. There is no problem if you bring the circle over the edges between the background and the object (that’s why it’s so cool) but it’s very important that you don’t drag thecross hairs over the edges.

    Hi,
    Background Eraser Tool. If you want to remove a background from an image you're working on, there are many ways to do this using Photoshop. You could select the object you're interested in, copy and paste it to a new layer. Another way to do it is to use the Background Eraser tool.

    Thanks,
    Michael R.
