My Best Optimal Custom Image (Colour) Setting Combination for the Later Pentax Digital Bodies

Well, here it is:



The above was first tested out with my K-5, of which the hue output was always not correct for most of my Pentax digital lenses for all of the built-in custom image profiles, even for the Natural profile, which was supposed to be colour accurate. So, I sat down to think what's wrong and observed quite some of my old photos made with the K-5..

My conclusion was that green colours are lacking yellow. Skin tones are lacking red, orange colours could contain more red. Thus and therefore I made the above hue shift. Btw, the most unfortunate thing is that no official documentation could ever tell the user what are the actual effect and meaning for changing this setting! >:-o Nonetheless, one drawback of the above is Blue colours now contain more green, thus they could be more cyanish. But the factory defaults are too blueish for many things anyway!

Still, two obvious problems with the Natural mode is the lower contrast and saturation for most lenses and shooting situations and thus I bumped up both for 1 step. As for the sharpness, I found that the standard Sharpening method (parameter set) is yet the best and 1 step up will make the JPEG directly out of camera to be more usable, while balancing well with both sharpening artifacts and noise.

On the other hand, I noticed that some Pentax users said that the K-5 series bodies are a bit cool for the AWB. But actually I don't find the same. The AWB is accurate but the problem primitively lies with the wrong hue shift. In order to verify this, just set the camera in preset white balance in particular the daylight WB and then shoot under sunlight, this can be proven and confirmed, example test here. For instance, that is something like what they set:



So, the ABOVE is NOT recommended! The incorrect hue shift will not be completed corrected but yet new yellow cast will be introduced for quite some situations. After all, my recommendation is to leave the AWB at default settings, ONLY changing the colour profile is needed and will work.

With the same optimal colour profile used with my K-5, I put it into my Q and it still works like a charm! :-D





After all, I would not post any of my sample images this time. Just try it out yourself to see if it is better or much better and things have actually improved! :-) And, I am always happy to share even everything could just be "useless as usual", as what my haters and fanboys said! ;-p

and good to see that Ricoh supports older models with new firmware: http://www.dpreview.com/forums/post/52146161
Thanks. Nonetheless, I think urging Ricoh to roll out a FF K-mount Pentax soonest is yet the most constructive, isn't it? ;-p
I have tried it and I like it. It is better than the mormal "natural". Thanks für the good sugestion

I am glad that you like it, my pleasure to share! :-D
that's quite interesting...I use that too...months before...I read that on a several blogs ~ year ago...
just an example: "Try to set A2 or A3 correction to the AWB for a warmer color cast."
Seems to be that another blogger is right about rice: "He basically just collects junk around the web, making his website blog just a big scrap depot." Keep in mind, that is NOT my opinion about rice...but the latest articles I come to the conclusion: why reading ricehigh's blog ? No news anymore only complaints about ricoh....

You don't read text but just diagrams? I said changing the colour coordinates of the AWB is NOT recommended!
I have ecxatly the same colour setup on Neutral, but I set AWB depending on the lens mounted, i.e. my Sigmas has a blue tone while my other Pentaxs has warmer rendering, except my 1.4/50. Thanks anyway.
may i ask for your user's settings on K20d ?
allo?

If someone shoot only JPG. OK, he has a problem to know how the K-3 works with the color.
Put if someone shoot RAW, it is not a problem he can manage it with white balance and with a passport color checker to make a reference shoot for color.
I cannot understand this question, Rice? Why you want to intend with this?
