Info about My Tricolor Timelapse Photos

I've gotten into doing "tricolor timelapse" photos, tagged with

tricolortimelapse .

Basically, the idea is that you blend R, G and B photos (or CMYK) in separate layers. The image is almost the same between layers, with just a small amount of motion. The motionless parts stay "normal" in the blend but the moving bits are strongly colored.

Sistine chapel

Here's one of the best shots and then all the photos in the series :

For this series, I turned each layer in a black-and-white image. Then piled up six layers.
For the bottom three, I only blended R , G or B channel at each layer.
Top three I left out a color -- i.e. only leaving out R, G or B. Opacity of top three each is ~35%.

Feet in Pool 

Here are some notes: most images are a blend of 3 layers, using blending options. Set each layer to only blend one of the three primary colors (i.e. R, G, or B) and then set its opacity to ~50%. Each layer should have its levels adjusted so it's fairly light (as one is going to be layering a number together).
Some specific here: layer opacity ~75% with a bottom layer just blending R, G, or B channel

Museums (Met, Moma, Guggenheim)

Spinning the timecapsule

Initially I took the four original images, put them in layers and optimally superimposed them (using the "free transform" function in photoshop. Then put the bottom layer to gray scale and set  the other layers to blend just the R, G or B channels (with fill opacity of 100%). I also tried blending with all colors. Here's the final products:

Finally, I changed the saturation to get some posterized effects:

Found this a useful resource on the free transform tool:
