  • may i know if kuyper luminocity masks are 16bit?

    hi

    may i know if the tony kuyper actions/panal create 16 bit or 8bit luminosity selection ?

    for example i open a image ,it's a 8bit image and i keep working in 8bit more

    now i use kuyper panel v4 or v3 , does the panel create 16 or 8 bit luminocity masks?

    i have read http://goodlight.us/writing/actionspanelv4/panelv4.html and https://tonykuyper.wordpress.com/201...inosity-masks/

    but honestly i did not understand the webpapes linked


    thanks

    The action panel creates 8 bit luminosity masks regardless of the image bit depth.

      Mantra, have a look at Greg Benz's 'Lumenzia'. Also works in 16 bit depth, search either under 'Greg Benz' or Lumenzia.

        AFAIK any 16 bit mask when applied as a selection will still be an 8 bit selection due to the way Photoshop works.

        To stay in 16 bit would require use of Apply Image command

          hi Tony
          but in the homepage there is that the v4
          the V4 panel employs an entirely new 16-bit process
          thanks

            hi
            thanks lumenzia looks powerfull
            And the masks are created in 16-bits, allowing for smooth transitions in extreme masks.
            Interactive Luminosity Masks is free
            http://svenstork.com/essays/interact...inosity-masks/

            ILM does not use selections to create the masks which allows ILM to create true 16bit masks (in the case of 16bit images)
            in short i can not understand if they does use Apply Image command to create maskes
            thanks

              Hi Mantra
              Not sure how the new masks are actually formed in version 4 but can certainly accept that they are true 16 bit.

              The old method used channel selection steps that are 8 bit (hard wired into PS)

              If I understand correctly the newer method of making the masks is indeed a full 16 bit workflow, however when the mask is applied it has to be applied in 8 bit due to the way PS is hard wired.

              While the 16 bit masks may be smoother it may not be apparent in many image manipulation scenarios. However given the choice I would opt for 16 bit as it could not do any harm (AFAIK)

                Mantra, I will get hold of Greg Benz, and find out what the facts are. Will be in a day or two.

                    seems the last version uses calculation
                    like https://tonykuyper.wordpress.com/201...inosity-masks/
                    there are screenshots but he does explain how get midtones

                      I use it, bought it when it was released. Very versatile, use it on most images.

                        hi
                        before buy it can i ask you a question ?
                        i watched some tutorials
                        but in the image linked , i can see 2 cross(es)
                        on the right of (e) and 10
                        can i know how does it work ?
                        thanks

                            Mantra: in terms of the two crosses, they basically determine whether you have a wide or a narrow mask depending on the zone selected. I use Lumenzia regularly, and have left a question with Greg re 8 versus 16 bit. He travels extensively overseas, so may take a day or two for the response, but I will post as soon as it is in.
