I think I also understand the -0.3 ev mentioned in the post above. Gives you a bit faster shutter speed and helps keep the spotlighted areas from blowing out?
I recall your thread asking about the best Pentax for low ISO and on a look-see basis only, I thought the K-7 looked best at ISO100 followed by K-x, K-r, K-5 then K20D (the K10D did not have the same test samples to compare).
To think of it if I had a K-7 - either it, or I, would be sitting at home -
the dark jazz venue I shoot often is at ISO5000, f/3.5 to as low as 1/4sec!
Yes, the -1/3EV compensation is a slight safety to prevent blowing out the highlights - I also have highlight correction On -
even with the "belts and braces" - Brit expression for double-safety (Brit braces = US suspenders; Trivia: Brit suspenders = US garter belt - so a completely different meaning/context
) I can still get blown out highlights on important parts of the photo - like this shot -
ISO5000, f/4.5, 1/100, 95mm
because of the strong harsh stage lighting - I had to use recovery and adjust the exposure via ACR on this JPG - otherwise Hiromi (the female pianist)'s face would have been completely blown out.
Nowadays at the dark jazz club - I chimp
then adjust the exposure compensation for the shot -
that can vary from -1 2/3 stop to +1 stop depending on the subject/scene.
ISO5000, f/4.5, 1/15, 80mm -
this shot needed +0.7 stop compensation
to bring out the face which is in the shadow
and the white patterned shirt also fools the metering into thinking it's much brighter than it is........
But one would have thought this shot with even whiter shirt, being in the same spot on stage
- ought to need the same treatment -
ISO5000, f/4.5, 1/80, 68mm
but this needed -0.7 stop compensation otherwise the face would have been over exposed, and the background would have been too bright to depict the scene properly.
Again for extreme HighISO like ISO5000 - the blanket advice is to use RAW - but with the K-x I can get away with JPGs and seem to be able to get "presentable" results?
