Does K7 have profoto color space

Does it?

Google-ing right now, but I don't see it yet.

I thought that is something you can decide in the RAW converter (at least some of them).

Nope, Adobe RGB or sRGB are the only in camera options.

Gotchya. So the colorspace setting is a JPG setting?

That is what I have understood, you assign a colour space in the RAW conversion. There might be some cameras that can do this in camera (I do not know), but in case not, you can decide it if you convert your RAW files yourself.

(Edit: Just to comment that colour space is not unique to JPEG, also e.g. TTIF can use different colour spaces.)

I found a link that gives some info on the topic. One quote there says:
"Most raw converters will allow you to create files in 16bit that can be converted to ProPhoto RGB. Actually the native color space for Adobe Camera Raw is ProPhoto RGB."
Color Management for Photographers #006 @Digital Outback Photo

There is also another good discussion in
Choosing the Right Color Space - Professional Photography -

Best regards,

Actually this should be called as "Color Profile", not color space.
As color space has different meaning - for JPEG it's a YCrCb, for TIFF it can be RGB.

About ProPhoto - yepp, it's a pity that there is no support for this in Pentax DSLRs.

I do not get this, there is support for ProPhoto in all Pentax cameras, since you can assign this when doing the RAW conversion. And if using Adobe RAW, ProPhoto is the native setting.

It seems as you did not read the links that I posted, so if you are thinking about having the camera outputting JPEGs in ProPhoto colour space, that is something that would actually be not recommended due to the 8 bits of JPEG, and the requirement to use 16 bits when using ProPhoto in order to avoid posterization. E.g. if you want to send your images for print using ProPhoto, it is better to use 16 bits TIFF.

Quote from following link (same as before): (and there are many discussions saying the same on internet)
Color Management for Photographers #006 @Digital Outback Photo

"How to get images into ProPhoto RGB?
Most raw converters will allow you to create files in 16bit that can be converted to ProPhoto RGB. Actually the native color space for Adobe Camera Raw is ProPhoto RGB.

Any Downsides of using ProPhoto RGB?
The main issue with ProPhoto RGB is that you need to use 16 bit images all the time or otherwise risk posterization."

Camera raw files by definition do not have colour profiles. The profile gets assigned during conversion to a user viewable format.
ProPhoto is most certainly supported with Pentax DLSR cameras, or it is by the software I use. My default working method is to convert to prophoto 16 bit files during raw conversion.
