I love capturing atmospheric optics which include things like rainbows, halos and sundogs.
The morning of August 31st provided me with a small narrow line of showers perfect for morning rainbows. I headed out with my Pentax K-7 and my Sigma 10-20mm super wide angle lens and got on the East side of the line of showers. In order to get the best full rainbows you need the sun to be hitting the cloud full on while still low in the sky. This typically means when the showers are first popping up or you will end up with to much cloud cover to get any full shots.
The rainbow this morning went from a single to a double in short order and was persistent for quite a long time giving me a nice collection of Kansas Double Rainbow photos.
I tried out various foreground scenes in a hurry while trying to stay in front of the rains but remain close enough to keep the rainbow right close and vivid.
It turns out that you can actually toss quite a few things in the foreground when the rainbow lasts this long which is rare. usually the clouds block the sun partially or in full and it's a done deal.
If you have tried catching a full rainbow then you probably realized that it rarely fits fully in the picture and especially a double rainbow. Along comes the superwide lens. My choice was the Sigma 10-20mm which was the most affordable lens for my budget that would still do a good job.
If you have captured one this close you also realized that your camera is likely going to get wet. Generally that will spell doom for a digital camera but since my usual photographic outings involve storms and rain I opted for the Pentax K-7 with its weather sealing. Now you can get weather resistant lenses but in this case the Sigma 10-20mm is not and so you do run an increased risk of problems but I do feel better that the camera is still sealed.
Remember that my photos are available for purchase for prints or digitally for commercial and hobby use on KansasHorizons.com.
