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
