Black and Yellow
Along with the pink flowers, there were this (these, if you read this any day after it was published) multicolor flowers. I had the exact focus be in the middle of the black and yellow flower. While the center is clear and very detailed, the focus dissipates very quickly once you look at the outsides of the flower. To fix this, you can increase the aperture (make the number bigger since it is 1/that number) to soften the focus.
