Body Shadows as Mask
I have picture of person in swimsuit and you want to put them in a wetsuit. Just to paint it on leaves it one dimension. To add another dimension with shading leaves you guessing as to body contours, highlights, and shadows. If you could use the convert image to B&W , make image really high contrast, and apply as mask in theory seems like it would work. There are so many ways to work photoshop there must be a way. My efforts have not yielded much. Has anyone tried this with better success? |

Re: Body Shadows as Mask
Here is a good strong shadow image which should work well for this exercise.  |

Re: Body Shadows as Mask
This one intrigued me and it's a really rough image, especially around the hair, but I’ve got to pack a case as I have a plane to catch. Hopefully it gives an idea of how I went about this ‘wetsuit’ image. First you have to clone out the bikini which, hopefully, you will have time to do a lot better than this. Now draw a selection around the body where you think the wet suit would fit. Keep as tight as possible to the skin or you will find that you have a black line around the wet suit. I didn’t have time for the niceties of selecting the hair - sorry. Now copy the selection twice to two new layers. Fill the first new layer with a very dark grey. Change the blending mode of the second layer (topmost) to ‘Luminosity’. You should now have a rather light grey image. Add a ‘curves’ adjustment layer and drag the curve down to make it very dark. I then duplicated this adjustment layer to make it even darker and then reduced the opacity and erased parts of this in the adjustment layer’s mask. It’s not a great tut but it’s all I have time for. Back next Monday. Gordon

Re: Body Shadows as Mask
I created an adjustment layer (curves) for layer 2, but it just makes everything dark. How do you just make the suit turn dark. I made the selection and copied and pasted the marching ant selection twice. Hope that is how it is done. |

Re: Body Shadows as Mask
Hi cy, I used pretty much the same technique as GKB merged the layers then used dodge and burn to get the highlights I wanted. What a lovely body to work with!! _________________ My fake plants died because I did not pretend to water them. |

Re: Body Shadows as Mask
You did a great job! My skill levels are a lot lower, and still do not understand how you get the wetsuit turn dark without the whole image turning dark. Using GKB's instruction I had layer 2 selected and then clicked on icon "create new fill or adjustment layer" and selected curves (fits well this this subject). When I adjust the curves the whole image gets affected, not just the wetsuit which is layer 2. What am I doing wrong? |

Re: Body Shadows as Mask
Hi cy I think I know where you are going wrong now, when you use a layer adjustment you will affect every layer beneath it. So what you want to do is (shortcut) press CTRL +M on the pc to open up the Curves dialog this will only affect the selected layer....try that!! _________________ My fake plants died because I did not pretend to water them. |

Re: Body Shadows as Mask
I am back to this exercise, and can't seem to repeat it. Can someone set me straight? I make selection, copy it twice to different layers. Rt. click on layer 1 and select layer properties - gray. Select lalyer 2, rt click and select blend option - luminosity At this point image still looks same rather than light gray as GKB says. Press Ctrl M and bring up curves and adjust to blacken layer 2. Do not get the dark gray tones as GKB did. |

Re: Body Shadows as Mask
You can use curves on just one layer. After you have created the curves layer. Press OK then CNTR/ALT/G that will confine your curves adjustments to the layer below only. Now click on your curves layer and you can make adjustments, and go back and change them later. |

Re: Body Shadows as Mask
I have the wrong sequence or something as it appears that layer 1 does nothing. It does not change the image when I use "select layers properties- gray". Then when I adjust the curves on layer 2 it makes the selected area darker, but the skin tone shows through in the highlights, rather than the gray. What am I missing? |

Re: Body Shadows as Mask
Cy I think what Gordon has explained is a very good technique. As explained, you should fill the selection with grey. The layer properties you refer to merely colour code the layer, to make identification easier. For example, if you were working on a multi layer image and you wanted all layers relating to one aspect to be recognised easily, you can colour code them. You will see the colour appear around the eyeball icon. See attached screenshot, which should help explain the technique. Here is Sarah's face from this weeks challenge, with a very fashionable mask applied. This has been done quickly, so please excuse accuracy. You will see that I've clipped a solid colour (dark grey) adjustment layer to layer 1, the area to hold the face mask. This gives flexibility and you can go back and change the shade at any time. The second copy has 2 curves Adjustment layers, as Gordon suggests. These have been clipped to it and will only affect layer 2. Again, you will not be making permenant changes and can alter the curves settings as you wish at any time. Layer 1 was copied and brought to the top of the stack. With a 'hide all' layer mask applied, I painted white to bring back the mouth. The pen was used to make a selection to tidy the mask. With the pen selection active. I applied a stroke of about 10px on a new layer and then bevel and emboss was applied to give an edge to the face mask. I hope this helps. Nick  |

Re: Body Shadows as Mask
Nick - Thanks for the screen shots and explanation. Any idiot should be able to follow that. Guess I am exception. Still can't get the same results as you and Gordon did. I make a selection and copy twice for layer 1 and 2. When I Select Layer 1 and add fill layer of dark gray the whole screen is now gray except for the selection in layer 2. When I select the blending mode of luminosity for layer 2 the selection is now shades of gray, and rest of screen is gray. Using curves adjustment level on layer 2 I can adjust the blackness. But what I end up with is a black screen and the shaded selection. In your example above only the mask would show, everything else would be black. I tried inverting selection for layer 1 but that did not help either. So when I select layer 1, click on create new fill layer, select gray color, how do I just get it to fill the selection and not entire screen? What am I missing? |

Re: Body Shadows as Mask
Hi Cy "When I Select Layer 1 and add fill layer of dark gray the whole screen is now gray except for the selection in layer 2" That's because you need to clip the adjustment layer to Layer 1. You can do this in a couple of ways. Either hold down ALT, click on the add adjustment layer icon and keep it held down while you mouse up to solid fill. Alternatively, once the Adj layer is in place, you can hover between layer 1 and the Adj layer and a symbol will appear. Click on this and the adjustment layer will jump to the right. See screenshot which shows the indented Adj Layer A 'clipped' layer will only affect the pixels in the layer immediately beneth it, so the grey will only appear where the mask is. Let us know how you get on. Nick |

Re: Body Shadows as Mask
Nick Thanks for sticking with me on this. The last instruction with alt key got me there, after I checked the box "use previous layer for clipping mask" in the new layer window. I read the instruction of "I've clipped a solid colour (dark grey) adjustment layer to layer 1" but did not realize that is different from just attaching it. Wrote this all down so can refer to it as needed. Thanks again. curt p.s. Guess I had better re-read Steve's book. |
