Update:
Found it...in my case is on the side close to the mirror top....
Spray some air there...Nothing changed.
Now, it seems this is by Pentax's choice or accident....Some say it is a feature of modern cameras to slightly underxpose so one can correct during the RAW process, sort of a "exposign for the right" method
Of all the clutter in the net, these seem to make more sense
Underexposure Tendency of K10D and K100D
and here where
someone suggests a grey card test. Which I cannot get unless I try it myself
(BTW aren't grey card values in PS 128,128,128?)
Now i have to live with this, by overxposing some.
Question is how will this overxposure mess with flash photography?
Should i stop up exposure time or flash power?

meter is usually bottom of mirror box. It very unlikely unless
you touched it or something else. Adobe RGB put middle grey at middle so it should match any hand held meter if you want to check that way.

hmmmm Camera is set to Adobe RGB.I will check on the on the meter lens (where it is) but assuming it is dirty wouldn't the camera verexpose shots?Tim, how will overstopping will effect the flash operation/metering?Στις 5:01 μ.μ. Τρίτη, 6 Μαΐου 2014, ο/η Randy Little <randyslittle@xxxxxxxxx> έγραψε:
This also depends on profile being used. If you change from srgb which once the curve is applied to the linear data puts middle grey at 113 then switch to different profile with different curve will produce different results. Most cameras have change how the meter sets exposure based on srgb sad sad. Might be worth checking if you changed the profile your camera is using. If not maybe make sure the lens over the meter is clean.On May 6, 2014 9:53 AM, "Tim Mulholland" <tim@xxxxxxxxxxxxxxxxx> wrote:Help with camera underexposing the shotsKostas -I've used several Pentax models. Most recently, I've used the K20D and the 645D, and I believe that the Pentax digital camera that I used before was similar. In both cases, yes, I've felt that the camera underexposed the images. I made this judgement by looking at the images themselves as well as the histogram.My "fix" for the situation has been very simple - I just increased the exposure compensation by +0.5 EV.Good luck,
