K10D DNG format. Useless?

Hi,

So, after all it seems that DNG format implementation in K10D isn't good at all.

Size of K10D made DNG is 16,5MB while size of PEF is 13,3MB.

Why did they bother implementing DNG at all? The main advantage of DNG for me (and probably for most other) was smaller file size.

To tell whole truth, firmware used to test file sizes was v0.2, let's hope v1.0 will be different in this area.

That's strange. I always convert my PEF files from my *istD to DNG shaving some 60+% off the file size.

It seems that they are making some kind of compression for PEF files therefore their size increased just ~30% compared to 6Mpix Pentax DSLRs while megapixel count increased ~67%.

It seems that Pentax are not using losseless compression for DNG, so size from 10MB (of 6MPix DSLR PEF) jumped to 16,5MB.

I expect that K10D PEF file converted into DNG by Adobe DNG converter will be 8-8,5MB... (5MB + 67%).

I still can't use either Bibble or Photoshop to convert my RAW files from my K100d.. Just that crappy Pentax lab software (or Silkypix which I don't want to buy at this point)..

So I have no doubt for the first few months I will be using DNG just so I can use a half decent RAW conversion program ;-)

joele, what makes the Pentax lab software crappy? I won't be getting my k100d until tomorrow, so I'm not familiar with the software. Just curious as to what I can expect. Thanks.

Beta firmware.

Don't forget, the firmware is still in Beta. We really don't know what we will get until the final version.

MPrince it is just no where near as good a workflow than Bibble, you have to open edit (with floating edit windows) and save each file seperately...

Bibble is much easier and faster to batch process all your images..

Thanks. I've been trying out Silkypix (free mode) & Pentax Lab to potenially replace RSE.

I couldn't figure out a clean workflow in Pentax Lab for the life of me. Silkypix is better, but I still prefer the workflow of RSE. I like the default outputs of Silkypix better than RSE though.

True. RawShooter's workflow is clearly the bes, however conversion quality, especially colour accuracy isn't as good as competition. Red especially bad, it becomes kind of orange instead of red. Colour Engine helps a bit, but still not 100% satisfactory.
