The underexposure and blown out highlight equation.
« on: February 15, 2005, 09:23:55 AM »
Hi, folks.
If you were expecting an actual equation, sorry to disappoint, but I just wanted to know by how much you guys/gals are underexposing when shooting RAW. I've found that 1/3rd to 1/2 a stop does the trick. I've had to sometimes underexpose by a whole stop due to the typical digital blown-out-highlight problem.

Just wondering what compensation other users of this forum are dialling in, and if it's similar.

I usually have the exposure compensation dial set for -1/3EV (or -1/2, if the dial happens to be on that side for whatever the reason). In some situations, I go down to -2/3EV for default setting.
If you shoout RAW, up to 2 steps of underexposure is usually no problem (although you get more noise than with a "properly" exposed image).

I've found that the exposure metering in the 7D sometimes goes a bit off, and I therefore use the exposure compensation quite a lot.

After a shoot at the zoo today I found that what looked ok on the camera was about 1/3- 1/2 eV over exposed when I looked at in on my pc. No my monitor isn?t calibrated so that my have some thing to do with it.
