Originally posted by wombat2go Brooke, That is a beautifully exposed photo. I see it is with a K-5 at ISO3200 and at f/11. The O/P (and me) use ist ds which in my experience is quite OK up to ISO400 and a bit ragged at ISO800. So the ist ds will need a fair bit more direct illumination from the flash in a photo like that. ??
Went to K5's in 2011 for low light capability so I don't really think about it. Shooting dance in theater, I start at ISO 3200.
My example was just something I knew was done with a flagged, bounced flash. I probably went to f11 for ambient, with winter sun pouring in, big dynamic range. Doesn't really matter, flash exposures are always 2 exposures, ambient & flash so controlling the flash with bounce & direction makes the difference. In my example, I had a high white ceiling, all I wanted was fill without direct flash on the violinist.
Here's an everyday example. Wife got birthday flowers and wanted photo to e-mail daughter. Back lit on dining room table, 8 ft white ceiling, Yongnou 560 at 1/4 or 1/2 power, black foamy thing around flash, light bounced off ceiling. f8, 1/125 for ambient and ISO 400. I could've dragged the shutter and boosted flash power and gone to ISO 200 easy or gone to 5.6 or both and gone to ISO 100. .
