Don't beat yourself up if you loose this one. Sometimes people loose the whole bunch at first. Pics are good, not as good as up close & personal though. I'm on a cell ph, sm screen, super sm pics, not helpful for analyzing anything, so I'll leave the 'looking' to the guys. But black indicates rapid cell death, if you can't save that one, don't sweat it, just see it as a learning experience & walk away with a little more knowledge than what you had when you started. Stay with the forum & read posts till your eyes burn. There's a lot of info here & a bunch of good guys who are ready & willing to answer questions & offer support. Good luck!

PEACE!
