multiple exposure

| ->> Any links or tips on how to produce a multiple exposure image via CS4 using layers? The type of image where a skateboarder is flying through the air and he is recorded 5-7 times then merged into one image? I'm close but I need help. |

->> Robert,
Make each image its own layer, then make a mask on each layer that is above the base layer with only the skater showing (white) and everything else painted black on the mask.. That should get you closer |

| ->> I once found a way to do it by erasing parts of layers which created a very simple yet seamless image. Is masking more like cutting and pasting? |

->> Robert-
First, place each image on its own layer, then use CS4's Auto-Align Layers function (Edit > Auto-Align Layers...
If you shot the set of images with a tripod, your best bet is to pick the background from one frame and mask it out on the rest, to save yourself time blending them together.
From there it's just a matter of masking out everything but the subject in the rest of the frames. |

->> What Steve said. A little more detail...
The layering can be a bit tricky depending on your background. Obviously you have to shoot on a tripod, and most of the trick is making sure your frame rate is correct for the type of overlap you want to do (if any). If you're shooting someone in front of a solid color it's easy to mask using any number of selection tools in photoshop. If doing overlapping images I find it useful to set the above layer to 50% transparency so I can see through the mask and see how the overlap will work. Once you're done you set it back to 100%. The image on my homepage was done in this way:

Hope that helps!

->> Robert, to answer your question "Is masking more like cutting and pasting?" I'd say no. It is similar to what you mentioned doing with erasing parts of the layers but using a mask on the layers allows everything to be non-destructive. Using non-destructive methods will also allow you to undo anything that needs to be fixed.
So in using a mask, you would add each frame as a layer, apply a black mask, and then paint over parts of the mask to reveal the parts of the image you want to see. You clear those areas using the brush tool. black hides, white reveals.
Does that help at all or just confuse things? :)

| ->> Getting closer. David....Your plane image/link is a fine example. Since the rider is against a blue sky I don't need to match the rest of the frame with each layer. I just need to compose him as he floats across the frame. Let's use four frames to keep it simple. I can bring those four images into photoshop and stack them. I will use the layer at the top of the layers palette as my main/base layer. I can lower the opacity of that layer to see the layer below it. Now, how/what do I do to get the rider in the second layer masked off and "inserted" into the first/main layer? Are the third and fourth layers done at the same time? I owe you one if you can teach me this! |

| ->> I would use the lower layer as my base and then just turn on one layer at a time and apply a mask to it. Use the select tool with a feather of 2-9 on it and trace around the rider, leaving space for feather. Invert the selection then fill with black on the mask. Turn next layer on then repeat. Can use a brush to fine tune. |
