Claude: I don't often shoot rainbows but here are some tips I picked up from my landscape mentors: It is often not the individual rainbow itself but the surroundings and your relative position that will make a special shot. Trying to put the ends or end of a rainbow on an interesting spot or location will make a shot instantly more dramatic. If you have a double rainbow, such as you had then try to get the ends of both in part or your frame, even zoom in on that spot and don't worry about capturing the whole rainbow. The ends of two rainbows will be added drama even in a flat landscape. As for technical stuff, a polarizing filter will increase the contrast and darken the sky. A darker blue sky here would have really made the rainbow pop (vibrancy) and would have brought out more of the second and weaker rainbow. Polarizers however will make the shot two stops slower, making clarity more of an issue. Finally, a tripod really helps because it keeps the scene really crisp which helps make the soft rainbow stand out. Because rainbows occur in dimly lit conditions, e.g. storms, you are shooting in low light and camera shake will be evident. You want a fast shutter speed to reduce shake and reduce blurring by trees blowing in the wind (I can see a bit of this in zoom mode).... unless you deliberately go for really extreme blurring, but then you will still need a tripod because I am talking of 10 second or longer exposures. A guerrilla pod is small enough to almost always have with you or stow in your car. I've wrapped one around fence posts for shots like these. Cheers and good hunting.

Great shot!! this is really a great capture od an atmosphere and of a feeling more than only a landscape with rainbow !!!

Very cool that you got a double rainbow Roxy has some great ideas

Never tried shooting a rainbow - great job!!!

A double one too! Well done.

Nice shot of a double rainbow. Lost my perfect double rainbow pic about 3 years ago when my hard drive packed it in. Now trying to catch that shot again and have an external for periodic backup. Mine was nicely domed over a mountain, saw it from my back door and ran into the house for the camera and managed to capture it. We get a rainbow in the same area 2 or 3 times a year but nothing as spectacular as the one I lost. Keeping my fingers crossed. Good Luck on your quest as well.

wonderful

Beautiful composition geometry!

I haven't got many chances to get rainbows, and none of them have been to my satisfaction. I think this is lovely!

Tripod and polarizing filters help (brewgirlca), as does any attempt to darken the sky around the rainbow. I've not shot any, as I've rarely had my camera when they appeard; and I've not had a good enough lens to make it more than a whisper. Look for National Geographic forums where their photographers answer questions: Look for rainbows, as they shoot those kinds of things all the time. They also use polarizing filters for broad landscapes, so they know all the ins and outs of them. (It's one of the few alterations the magazine allows...odd too, because p.filters are pretty intrusive for a magazine that's so purist in its approach...) In any case, while this doesn't capture the full presence of the rainbow, it's an intriguing shot all the same, for the deep dark of the foreground, and that mysterious fence (half lit), and the deep blue of the sky. Whatever you didn't accomplish here, I like the shot for its mystery and late day aura. The rainbow's visible too, a thin gentle apparition. Good luck, if you pursue it. I know there are all kinds of expert tips online. I've seen some video lectures by Nat Geographic photographers which were quite informative. (I've seen them from other photographers too, but I mention NGeog because they do a great deal of landscape work.) It's an elusive subject, for sure.

Superb capture!

A zoom will pop your colors a bit and then there is a phantom rainbow in your photo too!
