Went to Buck Gardens in NJ today and found these large mallows. Had soft light and was getting a bit of subtle backlight. the backround is water.

Yummy! Beautiful backlighting - you were right to let that carry your image. I do wish it had a little bit more room at the bottom - I feel the greenery is almost cut off down there - it would have been nice to see a bit more stem.
Wonderful DOF - f13 did well at getting plenty of detail throughout the plant and still let the water fall away into the unobtrusive BG.
