    Hi,

    I have a lot of images I need to make clipping paths for. I've been using the wand to select the background (they're sharp images on a white background) and then selecting inverse, making a work path, saving that path, then selecting that path as a clipping path. When I save the selection as a path it isn't as 'tight' as the selection even with the tolerance set to 0.5 pixels.

    Is there a better way to do it, or do I have to go back to actually drawing the paths with the pen tool?

    Thanks.

    Drawing the paths is the best way to do it. After a while you get a lot better at it.

    Just out of curiosity, what do you need clipping paths for? (I know what they're used for, but what's YOUR use?)

    I've actually had better luck setting the device flatness to 8 rather than a lower number, at least for print work.

    I recommend getting a Wacom tablet - you can hand draw paths in no time with that puppy. After sing a tablet I can barely path or draw with a mouse anymore - everything becomes second nature. I agree with Macstudent - draw the paths yourself or clean up the "convert to path" outlines. you'll never get a really great path with "convert to paths."

    If it was me and time was of the essence, and I had clean easily-made selections from white backgrounds, then I'd save them as alpha channels and save the files as LZW TIFs.

    File size, schmile size.

    I'll try increasing the flatness and see how that works. Otherwise I guess I'll just have to use the Pen Tool for the moment.

    Thanks for the input guys.

    Joe, is there a reason you can't use alpha channels? Are you putting it in a Quark document?

    Bingo ;) there's just something fundamentally wrong with designers using mouses. :p

    That was going to be my suggestion too. :)

    yep... buy KnockOut 2 Photoshop's stock masking abilities are frankly sh*t. ;)

    Hi jayscheuerle,

    I guess I don't really need to use clipping paths, so I tried your suggestion using alpha channels and it works very well. I think be using them from now on and ditch the clipping paths unless I'm exporting to Quark or something.

    I don't know how familiar you are with using alpha channels, but you can often find one grey scale color channel (either the R, G, B or C, M, Y, K) that offers the greatest contrast between your object and the background can be duped and used as a starting point for a transparency alpha channel.

    OR invest in something like Knockout Pro.

    What is the main point of using alpha channels and or clipping paths or masking? I was never really sure as to when one would apply these techniques.

    usually to separate an element from its background.

    If you do end up wanting to do it the way you do now, for some reason, wouldn't the magnetic lasso (hehehe I think of wonder woman every time I think of that tool...lalala, I'm such a 'tard) be a much better choice than the wand? It will give you a very well defined path, rather than having fuzz on it.
