Too much saturation w/ K10D.

I've noticed that when taking pics of something where the color is already quite saturated the K10D really over does the color. It does this in RAW as well as jpg, tho default jpg setting is less so. I can't seem to cut back on the oversaturation w/ PP w/o the pic looking funny. Any ideas? Anyone else have this problem? Below is an example of what I'm talking about. It was shot in RAW (PEF) and simply converted to jpg w/o any PP. Notice my daughter's coat and pants.

The pink/fushia is really intense! It looks like it is ready to ooze out of my monitor. Does this just happen in sunny conditions? I have an *ist DS and have been dreaming of a K10D.
BTW - cute kid!
 
When i was a trainee audio engineer, recording bands and mixing EP's, there was this microphone that would seem to be notiveably louder than every other one we had in the studio.

Thankfully we had all these wonderful nobs and dials to make it sound different! We could make it sound just however we wanted. Softer, more low frequency, less honky mid range, more crisp top end.

Whatever you want, you name it and we could do it! It was up to us to actually create something and to make do with the equipment we had.

Imagine that...

Of course, people like Elvis and The Beatles back before my day, well they only started out with a handful of microphones, 3 track recorders and such. None of your 24 track digital tape, 48 track consoles, endless racks of versatile reverb and effects units.

That's probably why they never sold any records eh?

First off you need to tell us a little more about what you are shooting, and what raw converter you are using, For example, are you shooting in bright or Natural tone, are you using the Pentax software, silkypix, Capture one, ACR... etc

The reason i ask this is that i am many other users have found the K10 to be one of the best cameras in terms of hue and saturation accuracy.

If you are shooting RAW try setting your camera to Natural tone curve and set the saturation to -1 or some thing similar, that will change the appearance of the images on your cameras screen, next off, depending on what RAW converter you are using don't touch the saturation setting. If you are using the Pentax software, try some thing else.

Actually, I find the K10D w/ the default setting quite conservative regarding saturation. The problem with your photo is blow out red/magenta which is pretty much a problem with most DSLRs out there, & it doesn't help that the photo is probably a bit over-exposed.

Perhaps slightly overexposed. Have you tried to lower the exposure one notch in the RAW converter. I would like to see the difference.

The image is slightly overexposed, resulting in clipping.

The red channel is clipped by maybe a third of a stop. Since this was shot raw then any decent raw converter should be able to recover the clipping by reducing the exposure a little.

The real answer is to get to know how your camera's metering works in conditions like this and expose accordingly.

K10D oversaturates 8% but that is pretty normal. It has one of the best hue accuracy of all cameras out there.

Just to nitpick - the camera produces no saturation of any sort in raw - colour is supplied by the raw converter.

Its a good point. Still some raw converter uses the camera settings as default and then you can expect some oversaturation ( if camera saturation set to 0), at least when using Pentax photo lab.

LOL.

Sort of a familiar story, Ben. I have been saying this to my kids as well. ;-)

Silkypix has a fine colour controller which you can utilize for just such a situation. I use it and it works a treat.

It does, but I've rarely used it to be honest. If I get single-channel clipping I usually push highlight recovery sliders to "color" and "saturation" then compress the highlights a little to remove the clipping ("DR expansion") without darkening the whole image. However, now that you mention it your method would work better in situations like this, selectively reducing the saturation only where it's clipped.

Silkypix has a very rich set of tools for fine-tuning almost any aspect of the image yet still manages to produce rather good results at default settings much of the time, I love it.

This sounds interesting, I shall have to try it.

Silkypix is excellent for it's tools and results, but I am also drawn to C1 for it's workflow and results. It really becomes a toss up for me between the two.

The over saturation is more pronounced when the pic is overexposed like this one but can still be seen w/ more balanced exposure. I use Bibble Pro to PP. It was my understanding that RAW is just that...raw data w/ no camera jgp setting having any affect on the RAW data.

I need to get to work, later I'll PP the image w/ Bibble and Lightroom and post results.

The red in the pants in the shot below looks oversaturated to me. The Lightroom histogram does not show any red channel clipping. Taken with K10D and Sigma 17-70. Processed in Lightroom using default settings. The only PP is an increase in brightness using Lightroom.

You could desaturate the reds in lightroom to overcome this, I guess.

That's what I did in PP. Very easy in Lightroom. The picture I posted is before PP.
