Originally posted by Rico Ian good grief man which is it? The K-1MKII has "problems" with color or it doesn't. Now you are saying there is no problem they look the same. First it was the green channel with the dust "detail" and now the red channel now with this new elaborate comparison you are saying no problem exist at all with the color.
Never said the mk2 has problems with color. I however did say that I see a problem with NR and what it does, just as you could see in the green channel in the dust and how it removed a lot of the dust ( I will repeat this not a color issue) and I will say it again I see no issue with color and color accuracy. It how ever has to do with detail that is lost in NR.
Most of the work was done for your opinion that the issue that it was from how the cameras settings (wb, brightness and hue) that has no influence when using a raw file.
Originally posted by Rico Ian this is a simple yes or no question have you not in the past set up similar comparisons between the K-1 and K-1MKII here at PF and on DPR asking people to give honest opinions. Then turned around to say you had mislabeled the images purposefully to trick people. Or not labeling them at all like you have done here.
It was done to trick someone into giving an opinion, and if you read the post you we see that I said not to use the images exif data as it would miss lead you if you where to use them.
" Remember not to use the camera information on the photo's to pass your judgment on the images as not to interject some preconceived bias to the images that may sway or
miss lead your opinions and just focus on what you see
"
Some people won't give their opinion until they feel confident that what they see doesn't conflict with what they feel. Would you have posted an opinion without the reassurance of the exif data?
you hadn't until there was exif data included.
Originally posted by Rico There is a difference in "variance" between hue with respect to value with the files you posted but you purposefully mask that by first staggering the images which makes it harder for the eye to see the difference and b.
I staggered them so that you can see where one image starts and the other ends. The reason why you cannot see much of a difference is that there is very little difference and if you use a eyedropper tool you will see that the values of those patches be it Lab or prophoto RGB the difference falls bellow what we can see as shown in the red circles ?
Originally posted by Rico you clipped off the grey background which would make it obvious one image is at least a half value to full value lighter or one is darker.
I had included the full grey scale patches found in the color checker target so that you can see the grey scale, these values range from 238,238,238 to 32,32,32. This covers white 9.5(0.05 D) to black 2 (1.5 D)
The value of the grey background falls between neutral 6.5 (0.44 D) and neutral 5 (0.70 D) patches. if we don't see any issues with those 2 patches you wont see anything in between them I don't see what you are taking issue with ?
Originally posted by Rico It all depends on how you manipulated the files to sought your agenda.
How I set my data ( image processing) was to set the white 9.5(0.05 D) to 238,238,238 and let how the grey scales fall into place, if you call that an agenda then its my agenda to set grey scale tonal values with the known target values. This is what one would normal do
Originally posted by Rico So which is it now Ian? The K-1MKII has problems with the Green Channel. The Red Channel. Both the Green and the Red Channel. Maybe it is really the Blue Channel causing the problems with the Red and or Green Channels. Just maybe it is the long coveted Yellow Channel. Or is there really no problem with the color for the K-1MKII.
Serious minds want to know.
To say it again, I don't see any problems with color accuracy it is the NR and what it does to the detail and more importantly its detail in the red and how it uses surrounding photo site information to reduce noise. This smears information from the green and blue channels as seen with the dust in the image that was shown in other threads.

I'm not saying that you can't shoot wildlife with Pentax, just that it is more difficult to find lenses that fit this bill and photographers who are willing to spend high dollars for really fast, long lenses will tend to gravitate away from the brand.
It was the used market in Nikon and pentax that swayed me from pentax, the abundance in the used market. when I sold my sigma 300 2.8 in pentax mount( private sale) I did so at the price I could have picked up in a camera stored used sigma 150-300 2.8 OS and still be left with $100 dollars in my pocket
I frowned because that's the way of the used market for anything in pentax mount with long and fast, but it work for me because I got top dollar for the 300mm
I picked up a used 45 TS for $1500
