We are several weeks away from our first flowers of the spring, but seeing these gets me excited about doing some macro flower shooting in the coming months. As brilliant as the yellow is on the pedals, you might try -.5 or 1 Ev to get a little more definition revealed. I have found yellow flowers some of the toughest to obtain detail from.
