Originally posted by Marc Sabatella No, you're completely missing the point. I can see the differences; what I'm saying is that they are much smaller than the actual variations in real life scenes caused by different colors of light, and our eyes trick us into not seeing the latter. Given the pictures you posted, there is *no objective sense* in which one can reliably say which is more "accurate". Take that same scene, set your WB to either "daylight" or "flash" (to get the most neutral color), then take three pictures: one using incandescent light, one using flourescent light, and one using light coming in the window on a cloudy day. You'll get three *vastly* different photos - that's reality - and yet your brian will have perceived all three scenes more or less the same way. This is the subjective element I am talking about, and it's *huge* compared to the measurably *small* variations in your posted pictures.

No Marc, I do not think I am missing your point, I am just not in agreement with what you are stating as a fact.
I do realize that the human brain compensates for differences in color temperature when we are seeing a scene. That is the very reason we think an object has a specific colour or hue. If that were not the case we would have to say "the ball has a blueish hue at a colour temperature of 4300K". Fortunately that is not the case, as our eyes adapt, we can simply state that the ball is "blue".
If what you were saying were true, a simple adjustment of WB in PP should rectify the problem, when in my experience it does not. The real problem is that different RAW apps use different default tone curves and colour profiles connected to a specific cameras signal output. In my opinion Pentax has done a very good job with matching the default colours we see in a scene at a specific WB point with what image is actually produced. I know other packages can match what Pentax produce, but have yet to find settings/profiles for these apps that work as good and without lots of extra work as Pentax app, with all hues and at all WB settings, in most images.
If you showed any of these variants by themselves, it might be that no one would say that the colours were "wrong" in any of them. But if you placed them side by side, many would see the difference, and I think most would agree more with the Pentax rendition as it in most cases has more colour detail and look less "flat", out of the box.
And even if you were right and there were no way of saying which colour profile were most realistic, which I believe is not the case, we could really simplify this discussion by stating that many find the default Pentax colour profile + tone curve the most pleasing by far. That it in some peoples opinion is not a subtle difference at all, and that you will need quite a bit of work replicating those colours in other software packages.
This is a really interesting topic to discuss. Maybe we should start a new thread in the Digital Processing, Software, and Printing forums instead? I am sure we could get many more opinions on this topic over there.
Originally posted by Genshu Wow this is a great forum! Thank you for all the input. I am in the middle of a cross country move. When I get settled I'll take a closer look at all of this. Yes I am interested in the subtle color adjustments like in that great photo of that great kid.
Hey Genshu, glad you enjoy our exchange, I was afraid we scared you off with our lengthy, colour discussion.
As I said, if you primarily want ease of use for lots of images, try out the demo versions of Adobe Lightroom, Capture One or Silkypix, all are available 30 days for free.
If you don't need cataloging and are not working with large amount of images, give the Pentax software that came with your camera a shot. It is basic and is a bit slower than other packages, but otherwise it works pretty well. If you try out the Pentax software, make sure you download the latest update from here (MacOS):
PENTAX Digital Camera Utility 4 Update for Macintosh : Software Downloads : PENTAX
It fixes some bugs that caused some crashes in earlier versions.
