excellent knockout

The removal of the background is very well done here. I'm guessing a hand drawn path converted to a selection with antialiasing and a little feathering. Very believable and effective.

Thanks for your comment.
I have used a selection by channel.
In Red, Green , blue , you take the more contrasted channel.
You duplicate it. Then with Levels option, you try to obtain white for selection , black for empty.
After for very fine correction , you can use Dodge and Burn tools (to correct edge of the flower for example)
After in One click on the dup channel (Ctrl Left Click), all the white part of the channel is selected.(So if you want have the background selected use invert mode).
After it is magic!!! All you have to do to have a black background is to put all levels (midtones, highlights..) to Zero.
I used this technic on very complicated selection with tree for example. But it does'nt work if your photo has no enough contrast in channels.

Bruno

Thank you for the explanation. It's always valuable to learn someone else's approach.
