flsh poer too strong?

[RalphLambrecht]

it seems to me that my flash units are much stronger when using digital.why cwould thi be? my digital ISO(200 SET ON THE NIKOND800) is the same as my analog EI(WITH TMAX 400.

I don't know. I have used my D800 to test lighting setups with large format film. I haven't noticed any power difference between the two. My guess is you are slightly over exposing the film, but with the latitude of the film you aren't noticing it.

Can you provide some more details such as what flash units, cameras and settings?

I don't think that the settings have abything to do with it. I'm simply asking if it is your experience too that digital seems to be more light sensitive than film at the same ISO setting?

Yes, I think there has been a change , whether it is better meters, different ratings , but it is different. Not only with regard to film, but in the past few years digital cameras have been changing. Many feel that is no longer 18% as a reference point but closer to 12=13%

Nope, my experience has been that digital exposes very much like slide film. Which also seems to be how Nikon's matrix metering is optimized. I find that in contrasty light negative film will be more likely to be underexposed in the shadows if I rely on matrix metering. However the last tests I did on this were done with a D300 about 5 or 6 years ago. But my D800 seems consistent, and I have used the same meter readings from the camera to expose some 4x5 Velvia and got perfect exposure from it, so things don't seem to have changed.

I use a Sekonic flash meter to test my exposures, the same meter I use for film and I have seen no difference.

could having the camera set to'autoISO' make the difference I'm seeing? maybe it's raising ISO due to low ambient and the flash thepowerful flash is ignored, because ,it hasn't been present yet?
