isolation on white

after going through all the pics from zumba mastercalss with Naomi Mokoena I figured that this one might just be isolate-able. I caught a lucky break there - the tips of the hair were against a relatively light background, and Naomi is dark-haired, otherwise it won't work at all. I did have to spend some time with selection tools and eraser, but not excessive one

However, my predictable conclusion was that maybe I don't want to do that again :) shots for isolation are best done on plain background and with good light to start with. Then it's doable in a couple of clicks, like here. But it was a nice challenge and it worked reasonably well

I can't really explain why the reflection, except the angle was such (Naomi was on podium) that the soles of her trainers are flat and horizontal - necessary condition for half-convincing reflection.
