Mainly why I love my 50.
Nightime ambient light(on D80) no flash ISO 1600 f/2.0 ss 1/20 YES 20 LOL I dunno how she was extra still and I had an extra steady hand I guess.
That's my "try" at skin tone balance so far its been a HUGE learning curve for me. Perhaps when I get calibrated monitor it will help but so far its been struggle. Plus dd has baby porcelain skin and any attempt by me to "warm" her skin up leads to casts and unnatural(to me) tanned look.
Anyway I just love the low light capabilities for snapshots around the home.
Its great outside and I've got some pretty creamy bokeh off my 1.8.
One of my absolute favs with my 50 1.8 if I could just get the color balanced.
From our trip to MK in June 09 a Disney related if you can forgive my horrible exposure and that I totally chopped the top off the castle.

I so need something nice and wide next time. And less humidity hair.

It was so horribly humid(and we lived there then so were used to it) that I only took about 6 photos other than this. I'm so upset it was a once in a lifetime situation where my best friend and her family were visiting and I'm so sad I didn't capture more of our "half" day Fortunately DL is 6 hours away and we are planning to take a trip together this year. I had left early around 5pm(long story) but at least dd stayed along with my friends and attended Busch Gardens, Clearwater Beach, the Sea World's Aquatica, and Kennedy Space Center with them. Hey it was only $10 more than I would have paid the babysitter for those in between days only(not MK and Sea World). I had to work but met up with them for their last day at Sea World. Took tons of photos there.
