Originally posted by RKKS08 Please keep in mind that the DNG format defines just the structure of a DNG file. It cannot do it better, as the sensors of cameras even of the same brand are very different, and the data, no matter whether stored as DNG or PEF or whatsoever, don't mean the same from different bodies/firmware. The interpreting software MUST know details about how the camera handles its RAW data (as a first step the sensor values must be normalized). In this sense, not only the Pentax DNG is unique, but also the DNGs of every other brand's cameras.
As the K30 is new, not all software companies will have updated their software yet. And some may do it only for their next version, to force customers to spend some money on upgrades (instead updates for free). I heard this was a problem in the past also with other brands than Pentax.
That is not true what you say about DNG.
DNG is not unique to brand or camera that is one of his features!
DNG is based on TIFF but it has some extensions to make it function like the RAW file.
So basicly you've:
- RAW sensor data saved as TIFF
- camera exif (basic camera information)
- extra information needed to build the TIFF into an image (think about the colours of bayer filter for example)
So all the information the software need is inside the DNG file, no extra support is need for the camera or brand!
All DNG are therefore in essence the same, sure they might contain different information but they are all read and process the same.
The DNG Pentax make are the same as DNG from leica, Ricoh, Adobe, ect.
The problem with P1 is simplly that they didnt implement DNG in such a way that it is universal, paintshop does the same thing... Adobe for example have no such problems or limitaion. I can open my K5 files in Photoshop CS (1) from 2003 without any problems and that version havent received an upgrade since 2005 so go figure...
