My father-in-law and I were planning to do a mountain bike ride but as we pulled up to the lake we saw a storm coming up the lake. Soon after a very low rainbow appeared and, fearing it would disappear at any time, I started with a quick photo with a 35mm SLR and eventually ended up with the 6x7 on a tripod.
