  • Selection Artifacts

    I'm not sure how much of a tip this will be to most of you, but I wasn't using it until recently, so I figured there might be others.

    Most times, when you move a selection to another image, there will be edge artifacts showing. I used to try blurring the edges, painting the edges, and rubber stamping the edges. Try this:

    Make sure the proper layer is selected

    Layer/Matting/Defringe

    Choose a small pixel value of maybe 1 - 2 pixels

    Press O.K.

    If that doesn't do the trick, try a larger pixel value.

    What happens is this: When you select a pixel value of, say 2 pixels, Photoshop looks *inside* the selection area to determine the value of the pixels 2 pixels in from the selection edge. It uses this value, and stretches it back to the edge of the selection. If you have to go to double digits, it's probably better to remake your selection more precicely. Give this a try. It's a real time saver.

    I think I'm missing something Ed,

    I made a selection using the lasso tool and then clicked on layer and the word matting is greyed out and it won't let me select it.

    What did I do wrong?

      Chris,

      Did you move it to another image? You also need to make sure the proper layer is selected.

        Hi Chris,
        The reason it is grayed out is because you need to put that selection on it's own layer by first copy and then paste then make that layer active. When you do that you will see that the matting is available to you.

        It is really a neat tool just as Ed explained. Try it all 3 ways to see the different effects it has on your layer. It''s great for hair and trees where the background is dark and you want to put it on another background that is light. It makes that dark background pixels disappear from your selection and vice versa.

            Hey Ed,

            Thanks and you just keep coming up with these good little tidbits of info...this is great!...
            Thanks again I tried it and it's a really nice feature that I never paid much attention to until now.

            A thumbs up for you.

              I'm glad it's helping someone. Debbie chose better words than I did because you don't necessarily have to paste it onto another image. You could also copy it, then paste it back onto the image it came from. Either way, it makes it's own layer. I know it saves me a lot of time. Just think - I gave a tip somebody could actually use. Who'd a thunk it?

                We all stopped believing your remarks about being an amateur a long time ago. Everything you have posted has been a learning experience for us all. If that's being an amateur than I'm still working up to becoming one. Thanks again for another good tip.

                  How to simulate Load Selection from other document
                  by BrianF
                  I'm trying to go through some of the exercises in the Eismann book on retouching, and I'm doing one that involves using Load Selection from another document, to generate an edge mask, I think. Is there a series of steps I can take to get the same result in PSE3?

                  Hmm. Somehow it looks...

                  Thanks to Murray Mistermonday who suggested me to work whit 16 bits depht images, this gives a better quality mostly when I have to transform them in JPG files, but when I'm doing a selection (on the background) than I'm transforming (enlarging) the selection, I do have a strong line where before was...

                  what's the diff?
                  by memphishooter
                  I am looking at a lesson on selection tools by a Creative Live teacher, and he uses a de-fringing tool along an edge, basically anti-aliasing. The effect seems to be the same as for feathering. What's the difference?

                  Feathering
                  by Ben
                  Forgive me if this is the wrong forum but it looked the closest. I'm using Photoshop 6. I have found how to get the feather facility and the need to put in the number of pixels you want to affected. Now do I use the lasso facility to surround the area that needs feathering or have I totally missed the...
