In my honest opinion... pluck one out and do an indoor shot! Hehehe. I mean, if it is not that too trivial with the lady of the house (was this taken from your garden?) I would ask her to give you one and do a studio type of shot. Then use a macro lens highlighting the center part of the flower and use the orange petals (the perimeter that you like) as secondary blurred subject. The angle of the shot on the original image is not too enticing. Also, you picked the time of the day where the sun probably is too bright (though it can be controlled by camera exposure). If you have a white umbrella with you, that would make a very simple and effective soft box lighting! (Ding ding! ) If you are spending too much time on a shot... then perhaps there is really something that is not quite right with that. I'd say, it wouldn't hurt to have a second try. Kind regards, Frank.
