    Brush & Eraser with 0% Hardness leaves an edge!!!! Please look at picture!

    johns66888899

      Hi, I recently started having this problem with my erasers and brushes in Photoshop. Instead of leaving a smooth fade, when the basic brush and eraser is set to 0% hardness, a very vivid edge/line is left around and there is no smooth blend.

      Please help me figure out how to fix this.

          If you want a hard edge have you tried the Pencil or Block option?

            Reading her post, I assume the OP wants the opposite: her soft brushes result in a hard edge, which is not supposed to happen.

             

            1. Change your Color settings: Edit-->Color Settings, and check Blend RGB Colors Using Gamma 1.00
            2. Change your image bitdepth to 16bpc. Image-->Mode--->16bits per channel.
            3. load up the basic brushes brush set, and use those.

             

            Avoid painting in 8bit mode in Photoshop - it doesn't work that well. Very noisy blending in the edges.

             

            Photoshop doesn't allow the user to control the softness curve, and create a custom transfer curve for the edge blending. Resulting in less than ideal edge blending in cases. Krita allows for a custom softness curve.

             

            PS I stopped drawing and painting in Photoshop years ago. I now use Krita and ClipStudio instead.

              Hi

              I 100% agree with Rayek's advice on using a 16 bit workflow.

               

              However, I would not normally check "Blend RGB colours using gamma 1" when working in 8/16 bit color depth and the normal Adobe/sRGB color spaces. This can lead to several other negative effects e.g. Photoshop will only do normal blending mode in the gamma specified and a 8 bit workflow in particular does not have the precision needed to work in gamma 1.0. 

               

              There are a few other things to check though.

              Is the harsh edge only visible against the transparency checkered background?.  There is a display artefact in Photoshop which shows banding and hard edges against that transparency background. It is not present in the resulting image though.  You can easily check by putting a temporary solid layer at the bottom of the layer stack (say solid grey or white). If the harsh banding disappears then you are seeing that artefact.

               

               

               

              The second - if your brushes are acting abnormally, just to be sure, try resetting the brush tool

                Thank you so much for your thorough help! I reset my brushes, but I think you're right about the transparency issue. I don't think I noticed it was the issue because on dark backgrounds, like dark blue and black, the soft brushes left a hard edge.
