Blue Tint

I love the K-30 so far, but I notice that all of my pics seem to just have a slightly blue tint to them. In broad daylight it's not that bad, but I just did some evening shooting and it stood out to me. I haven't touched any of the color settings on the camera, so I'm curious as to why it's doing it. I hope it's not a dud. Maybe it's my exposure levels too... perhaps I'm not getting it right.

The evening shot was underexposed, but it's pretty blue. The daytime shot just seems to have a slight sheen of blue throughout the picture... am I seeing things or is this legit?

Check your white balance settings. Also, if you shoot in RAW and have photoshop play with the blue/yellow slider.

Right now, until I get fully used to it, I'm just shooting JPEG 16 ***. The evening shot was using a M 50mm 1.7. The day shot was using the DAL 50-200 zoom.

Open shade is blue. It looks like that is what you are shooting in. Open shade causes blue snow in shadows, too :-)

I also recommend shooting RAW and using Photoshop Elements or similar. It's as easy as processing jpgs. Click "Auto", slide a few sliders to adjust exposure/brightness and contrast to taste, level the horizon (please), crop as needed, clone out the beer can, baby stroller or wires. I can do it, so can you :-)

I couldn't find the open shade setting on the camera. I just looked through all the menus. I did, however, set it to natural in "custom image". I always used natural on the Nikon I had and it worked. I shot RAW on the Nikon for the most part. I will too eventually on the Pentax, I just want to get these little odd things fixed first.

Looks to me that your WB settings are just wrong because the EXIF shows you have set 'White Balance - Manual'

Not that I have given it a lot of thought, but I am going to confirm the point made by the OP. I'm a 90%+ RAW shooter, and still it is an issue that requires more correction than I have noticed in the past. It reminds me of my Ektachrome slide shooting days (and that really was a situation you could not easily correct). It is an image quality issue because it isn't very easy to fix perfectly with the way Adobe LR/PS are set up for color correction. Fortunately, there are far superior color correction options out there for finishing (such as Picture Window Pro - which is my mainstay for final editing). Still, its a hassle.

Open shade w/ blue sky has a temperature of about 10,000K. Overcast cloudy sky about 7000K. As opposed to about 5500K for sunlit. Presume you can set temperature with K30.

Or take a white surface (in the lighting you have) and use it to set the white balance.

Not On The Menu?

The white balance selection function isn't on the menu, it's on the four-way controller (circle-dial, right side middle). The bottom button on the K-30, the left-hand button on the K-5 + K-7.
After turning the camera on in any mode, press the 'WB' button and a menu will show (from the top) Auto, Daylight, Shade, Cloudy, Fluorescent, Tungsten, Flash, CTE, Manual 1, K3. The default is Auto, it can be user-set to manual. If you scroll ("up" or top button) back to Auto and press OK, it will work pretty well for most lighting, including artificial lights.

Thanks for all the feedback, especially you rbefly. That sounds simple enough to fix. I'll try it tonight when I get home.

I have noticed that AWB doesn't work too well with old lenses, it's best to use the fixed WB options I find for these.

White balance is something I haven't played much with, so I just want to confirm. If I set it to auto and then focus on a white object, it should fix itself, yes? I actually didn't realize I had it set to manual until you guys pointed it out in the exif. I should have paid more attention.

Sort of. It depends upon what temperature the ambient light illuminating the white object is. I'd suggest just trying the 'auto' pre-set for awhile, and see how you like it. JMO

What lens are you using? As SteveB said some lenses add their own tint. I find the 50-200mm DAL L kit lens renders cooler images. It's an easy fix with a single slider bar in post processing.

I used the M 50 1.7 for the fountains. DAL 50-200 for the portrait.
