That is a LOT of sunflowers. With an f/2.8 aperture in use, the background of an even moderately-long focus distance 50mm image becomes pleasantly blurred.
A Werner stepladder is one of my most-important sunflower field photography accessories. These flowers are very tall and human support is required to get above them.
