I was a long time JPG fan, but recently began using RAW a lot more.
With my 300D, JPGs are exposed spot on, or at least so close who cares.
I shot a wedding last week, and wondered if it was me. Today I did an engagement shoot - the first few shots in JPG, then, doh! i switched to RAW. I read off the histogram on the camera to make sure hte exposures were good.
I get home here and start to go over the pics - ALL the RAW shots are underexpoosed, most by a stop, some by 1.5 stops and a couple by 2 stops.
I plan on testing this later today, but before i bore you all with my test results I wanna know - have you experienced anything similar?
Today this happened indoor and out, 2 lenses, with and without flash, in Av mode (eTTL with flash). The histograms on camera look fine, but not in PS.

I recently started shooting RAW and manual/Av all the time. At first I was compensating for exposure by +1 to +1.5 stops before conversion. Now I just expose to the right and skip that step in conversion.

| I quite often get the same thing. I usually find myself upping the exposure somewhat when converting them. I just put it down to my bad technique and being scared of blowing out the photos. I should bite the bullet and try Alienyst's way and boost exposure to start with and go for it! |

| my raw files and jpg files are the same. However if your camera is underexposing be thankful it is not the other way around. You have very usable files while if you were over exposing they would be nearly useless |

I don't think exposure is affected by using either the JPEG or RAW. One way to test is to shoot RAW+JPEG and look at the exposure on both versions. I'd bet the exposure would be the same from a same shot regardless of the version.

check this thread out for the answer to that- scroll down to the baseball pics- I think you'll be suprised.

Prof- check this out on histograms, it'll open your eyes...
Luminous Landscape- Histograms
then check out how to Expose to the right easily
Luminous Landscape- ETTR
the chart is what finally made me understand the way a digital sensor captures low light and why noise becomes such a factor!

| I have done what you suggested. The physical exposure may be the same, but the pics look very different due to how the camera processes the different file types. |

I have found the D70 underexposes (or under-meters actually) everything just a bit. This is the thread I started earlier this year when I first noticed it. (BTW, thanks for posting this, it reminds me I haven't posted results back to that thread).
Gordon's histogram enlightenment may prove useful as well -- It is certainly something to be aware of while using the camera's histogram.

| I use a RAW plug-in for The GIMP and it was underexposed, but I found a 350D camera profile for it and it comes out fine now. |
