(Carnival-ride and moving traffic lights at night and water-wave shots being the most popular subjects for this technique.) All three colors of course being recorded on one frame when done this way. Anything moving in the scene would get their share of individual color exposures. Those of you who might happen to have some burst sequences laying around might play with this in an editor. Just split each image to its RGB layers then recombine one of each from individual shots that are spaced moments apart.

If you enjoy gaudy colors, such effects are much easier to accomplish in photoshop with some simple manipulations that would allow more control over the variations in color.

In fact, long before turning into a gimmick, it was one of the first techniques used for full color photography. -- Regards, Robert http://www.arumes.com

Yes, but done on 3 separate B&W frames. Here's a fun freeware tool to make the above-mentioned process a little easier. http://www.mediachance.com/digicam/rgblights.htm I couldn't find any of their old freebies on MediaChance's new website, but luckily this old link from my bookmarks still worked. See this page for more of their handy free tools before it disappears. http://www.mediachance.com/digicam/index.html I highly recommend the free Blackframe and FilterSIM tools. Their free FilterSim tool once recovered an old and badly color-shifted image someone wanted me to restore for them, that no amount of color-balancing in other editors could accomplish. Their other freebies also have their occasional uses. Their PhotoBrush, DCE AutoEnhance, and Dynamic Photo HDR programs shouldn't be discounted either. Their Dynamic Photo HDR is far better than the usually recommend Photomatix. |
