    gradient reflection masking angle

    inquestflash Community Member

      hello photoshopers

       

      im trying to figure out the right way to add a gradient mask but on an angle on my image.

      i have cut out batman and trying to give him a reflection.i have made 2 reflections using gradient mask

      the 1st one is just vertical flipped and i have added a gradientr mask,the 2nd  image i flipped the image

      and added a gradient mask,but i also used the skew and distort,but the foot looks a bit odd,due to the skewing

      and distortion.is there a better technique to achieve a better and more realistic reflection?

       

      thank you.

          It’s called »painting«, I guess.

          If information is missing in an image (in this case the parts of an object that would be visible in the reflection but not the refelcted itself) then one may have to create them to achieve realistic results.

          Though in this case that might also make it seem recommendable to create a separate layer for the cape as it is farther removed than the legs …

          Edit: That is assuming the object has depth and is not just something like a cardboard cut-out.

           

          You could also just try if Puppet Warp on a flipped Smart Object copy of the Layer might not help achieve a slightly better result.

            The OP is on the right track when he says Skew.  Holding down the Ctrl (Cmd) key while draging the middle right handle when Free Transforming the shadow layer, will do the trick nicely.  IME cylindrical shapes are more difficult because of the convex shape of the bottle's base.

              Assuming the figure’s soles are flat on the surface and it does not stand on tip-toes then one Skew will not provide a realistic result in my opinion.

                I would like to offer a method which is somewhat logical.

                The example  shows probably what I'm talking about,

                but I don't have the time to improve the result.

                 

                Step 1

                Use one image of Superman

                Apply a perspective transform so, that the feet are on a horizontal

                line. Or use shear (the upper line is approximately parallel to the

                feet line)

                 

                Step 2

                Flip vertically and copy

                Paste

                 

                mirror1.jpg 

                Step 3

                Apply an inverse perspective transform so that the line through

                the feet is slanted.

                Executed more accurately and improved by some trials, it should work,

                  OK, I guess we should try and be accurate, and Skew does distort both feet into unrealistic reflections.

                  This was done with a combination of flip and skew, but with each foot copied again, and flipped without any distorion.

                    I think the feet could take more editing; counteracting the distorsion of the torso, head, legs and arms may not be worth the trouble, though.

                      Hello c!

                       

                      thats wa great image of the batman relfection.looks relealistic like the lights right above him.so how did you get the result?

                      can u please post the steps.

                       

                      thank you.

                        u2a.jpgoops,taking a better view of it,i spoted a distorion on the knee level.but still is a good enough approach.

                        im thking if maybe in ps 3D there might be a way of adding lights coming down from a corner angle to achieve realistic reflection to it,

                        do you know if i can do such a thing?

                          The Cape is on a Layer of its own (with missing parts painted in) and the body layer has the cape removed – because those two elements probably are pretty far apart near the floor.

                          The feets’ reflections are painted.

                           

                          And you are right that at the knees the flattened distorsion is noticable – also at the upper edge of the boots it’s evident.

                          But I’m afraid Photoshop’s 3D features are no help here unless you are willing to actually sculpt the figure in 3D properly in another program.

                            oh you actualy went it into the hassel and painted some parts.well thank you very much for that C,i wish in future there

                            could be a tool in ps,that you can control the light where it comes from to make realistic refelctions.maybe in cs7.

                             

                            best regards.

                              That is nicely thought through Christoph.  I actually looked for an image of a person standing on a reflective surface to get an accurate idea of what the reflection should really look like, but didn't find anything suitable.  At the end of the day, it doesn't matter how good your Photoshop skills are if you don't have a clear mind picture of what you are trying to depict.
