Yes, this is real. I made this image as a panorama so that I could fit in the rainbow end to end. I did enhance the blue of the sky so that the second more faint rainbow was visible. Never seen anything like this. I do have witnesses! Full Double Rainbow in my Backyard - 136/365
"Melkbosstrand Sunset Panorama" 50/365. You really have to have this image fill the screen to appreciate it. This is my first serious foray into a Panorama. The sky was kind of ho-hum with my 35mm f1.4 lens on the Fuji XE-2 but all of the parts left and right put together with what I saw would be what I wanted. I made individual images and stitched them together in Photoshop. Then I turned them into the exact tone I wanted in Black and White. Actually a slight Gold and Selenium tone. I really like it. I really enjoy requiring myself to make an image everyday as it is pushing me to be creative. At least in my mind.
