Pentax K10D underexposure problem

In the past six months or so, I have noticed a constant underexposure when taking pictures both indoors and outdoors with my Pentax K10D. I am using the standard 18-55 lens. I have tried varying Modes, White Balance settings, exposure compensation...etc., but the problem seems to persist.

I am shooting in RAW mode. and use Adobe Photoshop Elements for my photo editing. Virtually all of the time, just clicking on "autofix" in the program adjusts the exposure and the photos are fine from there, but I am wondering what is causing this in the first place.

Possibly, I just have something set wrong on the camera, but I have tried a multitude of things to no avail.

Any suggestions will be greatly appreciated, especially if one of the clears up the problem.

What is the photo setting on the camera - is it set to 'bright' -default or 'natural' which tend to under expose more often than not? Other settings to check would be exposure compensation EX and metering options.

Are the histograms in the camera and Photoshop showing the under exposure? If not, check the calibration of your monitor. I thought my shots were coming out underexposed until I re-calibrated my monitor.

Yes, monitor calibration and room lighting while viewing are both important. As noted, the histogram is your best guide. You can test your exposure metering by photographing a blank white wall in even, indirect light. The histogram should be centered with the photograph itself being quite gray.

Are you really sure the K10D exposed brighter 6 months ago or did you not notice until recently?
How much exposure compensation is needed (eg +0.5?).

The K10D exposes in general on the dark side. That is nice if you post process your (raw) images (and you do so that's great), because it preserves the highlights,
but out of camera jpegs are often too dark.

My K10D had a tendency to meter to the left side of the histogram most of the time. This was discussed extensively back in the day. If your histogram is mostly centered, then you might want to check your monitor although if your monitor is out of whack a little, all photos will look darker, not just your own.
