The K10D is provided with two CD-ROM's which include:

  • Full camera manuals
    Detailed camera manuals in PDF format.
  • Pentax Photo Browser 3.1 (Windows / Mac)
    Image browsing (JPEG and RAW), organization, viewing and comparison, conversion of PEF (Pentax RAW) to DNG, detailed metadata (including lens used, Shake Reduction information) *
  • Pentax Photo Laboratory 3.1 (Windows / Mac)
    Automatic or advanced manual RAW conversion (including white balance, digital exposure compensation, noise reduction, lens aberration correction, tone curve and highlight compensation) *

* Note that both these applications are 'Powered by Silkypix'.

RAW conversion

As is normal in our digital SLR reviews I like to compare the supplied RAW conversion software and some third party RAW converter. The output from Photo Browser and Laboratory is identical which means they both use the same conversion engine, so we only need to include Photo Laboratory here along with Adobe Camera RAW 3.6. Because the current version of ACR doesn't yet support the PEF files from the K10D we instead used DNG's (shot at the same time).

  • JPEG - Large/Fine, Default settings
  • PPL- Pentax Photo Laboratory 3.1 (PEF)
  • ACR - Adobe Camera RAW 3.6 (DNG)

Color reproduction

Place your mouse over the label below the image to see the color from a GretagMacbeth ColorChecker chart produced using each RAW converter. As we noted in our K100D review (and as is true here) there is no difference between the JPEG from the camera (in this case the default Natural image tone) and the default output from Pentax Photo Laboratory.

Sharpness and Detail

As you can see the results from Photo Laboratory were very similar to a JPEG straight from the camera, if anything the JPEG has a slight lead on very fine detail (texture of the watch face). Both the JPEG and Photo Laboratory however suffer from a softening of edge detail which can be seen quite clearly when compared to the output from Adobe Camera RAW, note the crispness to the 'Heuer' logo and the number 2, both of which appear less well defined in the other crops.





Once again good resolution from all three with Photo Laboratory delivering slightly more detail at 2400 LPH than JPEG. And once again the biggest difference between the Pentax produced images and that of Adobe Camera RAW is the definition (sharpness) of edge detail, this most obvious in the numbers which run down the right side of each crop.
