  • Help with creating shadow

    I am making a composite night time street image in which I am trying to place this couple. The light source is coming from behind and to the left of the couple. Approx in the top left corner of the image I have attached. I have tried using a drop shadow and transforming it and also tried making a shadow from the couple and transforming it. Because the mans feet are at an angle the shadow just does not work. Any advice on how to get a realistic shadow?

    26 views and nobody knows how to help me. I was certain that somebody would know how to solve this problem :-(

      Views don't equal possible help!

        Without knowing the strength of the light source it is impossible to guage the shadow. Surely the lighting on the couple needs sorting out aswell?

          You are absolutely right, the lighting on the couple needs to be sorted as well.
          Perhaps I have not explained myself very well. The problem I have is actually creating a shadow that actually attaches correctly to the feet of the models and does not severely distort the rest of the shadow. I do not think the strength of the light source will have any effect on that particular problem. I would have thought that the only thing the strength of the shadow would effect is the density and drop-off of the shadow or am I missing something?

            Context is everything Colin and it's difficult without a few more visual clues. However i see the tilted shoes as a bonus because you can keep a sliver/wedge of light underneath which will animate the pose. I reckon if you get lighting sorted for the torsos, the shadows will suggest themselves.

              You can't just take an overall selection of them, fill with black, skew/transform it and expect it to line up with each of their feet simultaneously. You have to do it one leg at a time. Then also paint in grounding shadows at each foot's point of contact. Then fade and/or blur the shadow the further it gets from them, depending on the strength and character of your light source.

              Break it down into manageable components, each leg on it's own layer, then all grounding shadows can be painted onto one blank layer above them, and then perhaps all shadow layers into one group to be masked/faded as a whole.

                Thank you for that very helpful advice, much appreciated. I will try doing it that way

                  Sure. Let us know how it goes. Remember also to put your shadow layers in Multiply blend mode so that they blend into your bg.

                    Make a curve, pull it down to darken, and then just draw in a shadow.
                    Most shadows are quite simple when you look at them....

                      Perhaps I am trying to be too much of a perfectionist. I will give it a go and see how I get on! Thanks

                        Usually, i'm transform shadow with free transform (ctrl+t) and after that i'm using warp transformation for docking end of foot and begin of shadow))

                          As mentioned above, make a dupe of the people, fill it with black, flip it, skew and rotate to angle of light, then use puppet warp to move feet into position. Use lens blur or some other blur method to blur the shadow further from the couple, and add layer mask to also fade the intensity.

                            I'm new here... I do not know if this can help, I created the shadow with a 3d program, maybe you can try (or maybe is useless)

                              Flowbox, I've done that too, but using Photoshop's 3D features. In the attached image, I made a postcard layer of the illustration of the girl and put it in with the balls, which were actual 3D objects.

                                Help with a bad shadow
                                by Canna W
                                Another bad shadow! I (very basically) restored and colourized this image for someone, and introduced a shadow.

                                I am very unsatisfied with the shadow. The child looks as though she is floating. I would much appreciate some help with this....

                                Cove Shadow Smoothing
                                by hillsadam
                                Hi, I have a new cove in my studio, but unfortunately when I light it minimally I do get a noticeable collection of shadow in the bottom,

                                Can someone suggest the quickest method to make this dark line less noticeable and a smoother gradient with least effort!

                                Thanks...

                                Can anyone help me with this shadow? Or can I ask how much it would cost for someone to take it off for me? Please and thank you! I don't have photoshop. I have a photoshop editor on my phone but I can't seem to figure it out...

                                How to straighten shadow
                                by jeroboams
                                Hello all,

                                This might come across as a stupid question but does anyone know how to straighten the shadow underneath this print?

                                Apparently it can be done without using the 'drop shadow technique' but I just don't know how.

                                Can anyone advise?
