Tried using my K10d today with the DA 16-45 for an industrial shoot. All were underexposed by at least (2) stops-even with flash. Any suggestions? They were fixed in PS-that shouldn't be necessary with this camera.

I have a model shoot this Sat and looks like I will use the old trusty DS unless this can be fixed. That has never let me down.

I've had similar exposure problems with mine. I have to shoot what appears to be over exposed on the display, to come out properly on the computer. Don't know if it's me (operator error) or the camera. I know that doesn't answer question exactly but… perhaps someone else can chime in and help us both!:-?

Most times I've had a problem with unexpected under/over exposure, if I changed the batteries it's solved my problem. I'm using the K100D and now pretty much back to CRV3 batteries as I seem to have less problems with them than rechargeable NiMH's.

Just my two cents worth.

I never had underexposure problems with my K10, unless it was operator caused. I would occasionally leave the camera on spot metering and forget to change it to something more appropriate,and envariablymetering off of the darkest part of the scene! I did have some over-exposure problems with one of my manual lenses, but even that seemed to be reduced when I installed the last firmware update.

Make sure you didn't accidentally change the Ev or the metering mode.

Thanks for all the imput-I finally had some time to glance at the manual-I read that the "front" E dial adjusts the exposure compensation (while holding down the exposure button)-so I bumped it up (1) stop and now it's dead on. Still don't think that should be necessary but making one adjustment is better than fixing shots in PS.

I always +0.5 EV when I using my K10D:sad:

Pentax's photometry is too guard butstill better thanoverexposure?

Hi, I've had both over and under exposure with my GX10. By now there is consensus that Pentax exposes to protect highlights and since the dynamic range is a bit less than competitor cameras, many shots will look under exposed.

You can do a couple of things - set the EV up as you have done, use the correct exposure mode for the subject i.e. spot, center weighted or matrix and thirdly, adjust your camera viewing screen brightness in the menu to accurately show what you will see on your computer screen,

Also, dont forget to set pix review mode to show the blinkies for over/under-exposed areas.

I've learned to understand when the camera will under or overexpose and get fewer duff shots now as I adjust from CW to Matrix modes according to the light and subject darkness. I use Spot metering for special shots when I need the dark areas properly exposed and can live with burnt out highlights.

I started with +EV but have gone back to 0 EV as I now haqndle my camera with greater experience.

However, the bottom line is that you will often have to do some PP work to get better balanced exposures as your lowlights will often be underexposed when the highlights are correctly exposed. This is a feature of the 'like a film camera' design philosphy behind the K10. Happy 'darkroom' work!

Be well

Every DSLR camera I've used has needed EV comp to the plus side most of the time. My standard setup is at +1/3 ev, and very rarely at 0. I'm always adjusting between +1/3 right up to 2 depending on the light situation. Once in a while, spot metering may be needed, but mostly I use average metering...cheers...Don
