Any tips for enhancing rainbows?
I've noticed that whenever I take a picture of a rainbow, it looks much less
impressive than it did to my naked eye. For instance this one from yesterday is ok: http://www.tednolan.net/misc/p1120927.jpg but looked much better in real life. Any tips for punching rainbows up in GIMP? Ted -- ------ columbiaclosings.com What's not in Columbia anymore.. |

Bracket the exposure aggressively. The colours will usually look much more saturated on the underexposed images (and the clouds darker). But the best compromise image may be just 1/2 stop away from the exposure that the camera would choose automatically. Even saturated pure colours tend to go to pastel shades when over exposed. The shot isn't that bad though and there is a hint of the larger and usually much fainter secondary rainbow at the far right. Regards, Martin Brown |

You should have adjusted the exposure by about 1.5 stop. Setting the correct exposure is easy on the LX3 with its live histogram. After that, adjust the curve to give the rainbow more 'space': http://www.arumes.com/temp/p1120927_edit1.jpg http://www.arumes.com/temp/curves_adjustment.png Note that the exposure only uses five out of eight columns in this view. The righthand three columns aren't used because of the underexposure. You can see that I use about 60% of the dynamic range for the 40% of the original exposure containing the rainbow. The other 60% of the original, which contains the dark areas like the chimney and trees, only gets 40% after the adjustment because these areas are less important. Look how much this makes the rainbow stand out. Finally, you may want to adjust the white balance and increase saturation a bit, to limit the color in the sky, and to make the colorful rainbow stand out even more against a gray background. http://www.arumes.com/temp/p1120927_edit2.jpg -- Regards, Robert http://www.arumes.com |

Yeah, there was a secondary rainbow, more visible to the eye than here. Ted -- ------ columbiaclosings.com What's not in Columbia anymore.. |

Here's one I did with curves in Photoshop, using Lab mode and layer blending: http://mike.russell-home.net/tmp/rai...20927-lab1.jpg The basic problem is an orange cast, and lack of contrast and saturation. This is an interesting example that, only with your permission, I'd like to make available to my forum for experimentation. -- Mike Russell - http://www.curvemeister.com |
