    Learning Photoshop CS3

    GESYMSB Community Member
      Hello folks, I am new to Photoshop CS3 Extended.

      There are some things that I used to do with another program, that
      can figure out how to do it with Photoshop

      1: On Photopaint, I used to click on the canvas, masking the white
      background lets say, and then I click on "invert" and the mask will be on the objects on the white background, ( anything that was not white )
      From there I could copy and paste or save the selection.

      How I do this on Photoshop, masking an object from a background ?

      2: On Photopaint I could said New from Clipboard
      and there is the new picture with whatever was on memory, however
      I try that and all I get on Photoshop is a white canvas the size
      of the object on memory, but just that, blank.

      Those 2 tips will be very gooooood for me if someone can help me....

      100000000 of thanks

          1. Layers and selections. PS does not use objects as in PPaint. To keep a selected part of the image separate, simply copy&Paste. It will be inserted as a new layer. From that you can restore selections any time by Ctrl+clicking on the layer thumbnail. Alternatively , explicitly save your selection as a custom channel (Select --> Save Selection). This also can be used to non-destructively retouching layers, if the selection is saved to a layer mask. Double-click the "Background" to turn it into a floating layer, apply the selection to it (dashed circle in the layers palette or Select menu again).

          2. Simply paste. As per the above, AE will create a floating layer containing your actual data. It's a minor inconvenience, but better this way.

            I'm new to Photoshop CS3--upgraded from 6.0 which I have had for a long time. I'm using a new scanner as well, Microtek Scanmaker 9800XL with the TMA. I'm experimenting with scanning negatives. I scan the 4 x 5 negs as 600 ppi .tif files, then reduce them to save as .jpg files. I cannot get Photoshop CS3 to save the images as .jpg files. It works fine when I do reflective scans. Is there a way to make the files .jpg files? Or is there a better format for reduced files?
            Thanks for any help.

              Erin,

              Are the neg scans 16 bit/channel? Jpeg doesn't support that. Go to Image > Mode.

              In any case, jpeg is
              i not
              recommended for anything but final output. It will re-compress and deteriorate every time you resave it. If you really need to reduce file size, Tiff has an option for lossless compression (LZW). But if you consider a 4x5 in @ 600 ppi a large file, it may be time for a new hard drive? :-)

              BTW it's better to start a new thread than bury your question in an unrelated one.

                Very good, I have if possible one more very important
                question, one of those things I use to do a lot on
                Photopaint......

                On photopaint I "MASK" an area, then paste a big
                picture and just click "CLIP TO MASK" so the
                big picture was cliped to the mask.

                How I do this on Photoshop CS3

                Also do you know a place where I can download "Basic Tips"
                on Photoshop..... Thanks

                  in the bottom of the layers palette there's a layer mask icon. you should hit F1 (help) and read up on masks. you might not actually need a mask though, you might be able to just crop to a selection. do a little reading and see which is more like the program you used to use.
