K10D problem

Darius4522 · 02-15-2007, 06:44 PM

I'm having problems with my new K10D (similar to one posted previously in this forum by Dave54 re his K110D). On auto, the shots look fine in the LCD when I review them, but on the computer screen they are really dark. I have saturation at 0, sharpness at +1 and contrast at +1, and image tone on high. Any suggestions? My monitor is fine, as pics taken with my Panasonic FZ5 look normal and much better than the K10D.

care to post a photo with exif? it's hard to diagnose a problem without much information. sharpness and contrast settings won't do that much to cause a problem....

Darius4522 · 02-15-2007, 07:41 PM

Here's a sample I took quickly..it's white vases against a white background...looks grey to me..and on the FZ5 it looks white....hope I have attached it right. Never done this before on this site....failing that I can email you. My email is johnm@adam.com.au

My photo retailer says Pentax do it deliberately to retain the highlights, and I should simply lighten it in Photoshop (which I don't have).

Hmmm... No exif. Can you post your shot data? (Windows, right click the original image, click properties, click advanced button. You'll see shutter speed, aperture, etc.) I have a feeling your WB is off or your EV is changed, but I'd like to see the data to confirm my suspicion.

Also what type of lighting are you using?

Darius4522 · 02-15-2007, 07:50 PM

This is the same subject with the pansonic.....ISO 60, f3.3, 100th sec.

The Pentax K10D was ISO 100, 1/125 @ f4.5.

Both taken at about the same range from the same spot within 2 minutes of each.

Darius4522 · 02-15-2007, 07:52 PM

The Pentax white balance is on auto, as it the Panasonic...interesting to see the noise in the Panasonic..... They are indoor shots, btw.

Does the exif give any EV Step or Exposure compensation value?

Hehehe. Smaller sensor in the panny. You'll begin to notice a few other things with both cams. My buddy and I are just beginning to discover them too. Pixel peeping - I don't do it too much.

Natural light. The room has two glass walls..plenty of light.....

What software did you use to process this version of the file? Have you used a (d)SLR before this point--how much? Not a loaded question-from the site you linked I see an accomplished photographer--but...

The histogram for this image is centered about middle gray-much as would be expected for 'white' shot two stops under...

Yeah I was suspecting that, but don't know how to change the EV in PASM modes on a K10D...was checking the manual...help?

Darius4522 · 02-15-2007, 08:01 PM

Not that I can find on the LCD screen... apart from +1 sharpness and +1 contrast plus highlight tones. Saturation is at zero.

Oh, you still have the shot in your SD card in your camera? Please go to review the pic on your LCD and tap info twice. You should see a histogram, and a ton of shot information. The screen should have an EV value there...if it is negative, that is your problem.

Darius4522 · 02-15-2007, 08:05 PM

jfdavis58: I have not used a digital SLR before. Only an ancient 35yo Minolta, which still takes might fine pics, specially when using Fuji Velvia. Apart from that, only the Panasonic. I admit to not having downloaded the pentax software as yet as my normal computer is only Win 98, and it won't work with that. So I am simply opening the Pentax pics in a freeware program called Irfanview.... Could that cause a difference? That never occurred to me.

Assuming he is off the green mode: mash the exposure comp button (+/-) on the body backside and dial it in with the front e-dial.

In hyp-M you just dial it up two stops with either the shutter or the aperture or both-comp not available.

In the green mode, well, I just don't know--it's the green mode.
