Being a redhead it's quite possible she has very light skin.
There's no numbers on the photos but the one I checked that looked most like being over exposed, the skin exposure was indeed over exposed, but not blown out.
I use Camera Raw to check Caucasian skin exposure. Correctly exposed skin highlights will be between 235 and 240 in the RGB red channel. In the photo I checked the red channel was 252 to 254. 255 is the maximum value for a channel or 'blown out'.
FWIW - putting some white space between photos really helps with their presentation and numbered photos aid C&C if more than 2 photos are posted. Not everyone's screen is set to the same pixel dimensions. So what I see as 1 row of 4 photos above a row of 3 photos may be displayed on someone else's screen as 3 rows of 3 or some other combination.
Is this just a fun shoot or a paid shoot?
