Jeff,
http://www.tonygamble.org/Arabella_Dorman_web/index.htmlAll last night's shots were using Auto and Auto ISO with never less than an aperture of extra exposure. Lots were 1.3.
Nothing blown apart from the Apple on the lady's computer - and that not often.
So I have masses of shadow detail and if I need the screen image behind her I reconvert the RAW with much less fill and combine the two jpgs with Picture Window Pro.
