    This sounds like more of a Photoshop or Photoshop Elements question.


    But dithering has to do with how the program assimilates a color gradient in a file without much color range. For instance, if you convert an RGB or grayscale photo to pure black and white, shades of gray will be converting to dithering, or a pattern of little black squares, as in the illustration on this page.


    Though dithering can also have other means in other digital formats, like video and audio.


    What context are you seeing it in?

    No, it's a very good question. I had to struggle to articulate the answer!

    Well, the challenge is e-mail itself. You can't send large images over e-mail. And even if you can, it's not a good idea.


    More often, it's wiser to post the photos of your work to a web site and then e-mail links to it. Photoshop Elements and the Elements Organizer come with links to, a site that includes lots of free space for displaying your work.


    But you can also use sites like Flickr and Picasa too, of course.


    If you're determined to e-mail your photos, it's usually not a good idea to send photos much larger than 800x600 pixels in size. That's probably not enough to show much detail in your work, but it's enough to offer a medium-resolution proof to your clients.


    I cover how to do a lot of this in my Photoshop Elements/Premiere Elements, if you're interested. Reading it would be much easier than trying to hunt and peck away at answers on this forum.
