Originally posted by switters Hmmm. I can't say I'm totally thrilled about this. I know every camera/system is different and has its quirks. But accurate exposure metering is just something I didn't have to think much about with the 20D, and I liked that.
Making sure the +1/2 or +1 exposure comp is always set, and remembering to overexpose in manual by that amount (which is the mode I shoot most often in) is kind of a hassle. But I guess if I love everything else about the K10D it's one I can learn to live with.
I could configure the User settings in Aperture Priority, for example, with +1/2 or +1EV compensation. I'll check the manual, but I'm assuming exposure compensation resets when the camera is turned off in other exposure modes?
Any other tips would be appreciated. I'll post a few pics later as well.
Couple of thoughts that may or may not apply:
1)There are few RAW histograms (none in a camera I believe). The histogram you see in most (if not all) cameras are based on the jpg rendering. A RAW file (prior to tone curve and gamma correction) is dark, ugly and tonally compressed with the best exposure.
2) RAW editors may have presets and their own idea of tone curves (and sharpening and exposure and white balance, ect) so they can be quite different from the "in-camera" histogram.
3) Accurate is really a matter of interpretation. Technically Pentax and Nikon (upper level models, lower can have meters tweaked ala Canon) have more "accurate" meters IF you consider the iso. Canon renders a more "accurate" image because of the iso fudge. Remember, technically they are "overexposing" by a 1/3-1/2 stop in a technical sense. Which one you prefer is a bit personal. I like the Pentax meter response in general and have no issues w/ darker images. To me they process better than losing highlights or having a lot of lost data in the brighter areas. I browsed a lot of Canon images before buying my D and didn't like the amount of blown areas in many "straight from the camera" images. I also noted that MANY of the best shots by the REALLY good photographers had a negative exp. bias dialed in per the EXIF...
I don't know if you ever saw a person named "Daniella" (I believe, but she seems to get banned frequently at dpreview
) but her bird photos are amazing and almost everyone had a neg exp bias dialed in...
I won't get into conversions and color spaces either since this is all really my own thought gatherings and subject to error....
this is a fun read as to HOW a RAW file is treated in the converter code (and of course how you can change things).
