    erasing or brightening up background

    Level 7
      There have been many questions - and answers - about erasing backgrounds in
      this group.
      I did not read and try all of it, although I did try quite a few,
      but the image I have online here http://www.xs4all.nl/~hogen/test/spin.htm
      still causes problems.
      Perhaps the contrast is too low?

      All I want is : to get rid of the grey background and replace it by white or
      transparent. I would be happy if the contrast could be upped so it wouldn't
      look so dull.

      Thank you.

          The jpeg is in pretty rough condition, but I gave it a shot. You can
          grab my PNG file at http://www.newmediaservices.ca/jim_babbage/spin.png.

          I used Find Edges and Brightness/contrast Live Filters, then the magic
          wand for selection, expanded the selection by 1 pixel and then converted
          the selection to a path. The selection (or path) could be worked on more
          to increase the definition of some of the strands.

          Hopefully this is something close to what you're looking for.

            It's over compressed. If you still have the original, export it in GIF
            format and post a link to it again.

              Adriana,

              Out of curiosity - why this image? I mean, it is so easy to either find,
              or take a picture of a cobweb that would be easier to work with.

                Thank you, Linda, but I have never had the image in gif format.

                  Did you have it in a larger size?

                    Exactly. That image has so much JPG compression artifacts that it's
                    basically unusable.

                      No, unfortunately not. I am not a professional, as may be obvious, and
                      wonder how you and Stéphane can immediately see that the image is
                      compressed. I can see it is a bit fuzzy, but how do you tell?
                      Thank you.

                        If you zoom in 200% or more, you'll see the wrinkly compression
                        artifacts around the lines in the image.

                          I see what you mean! Thanks for explaining.
