Originally posted by vonBaloney My big question is what sort of files will it produce and what software will be able to deal with these files? Are we talking jpg-only after in-camera synthesis? (There was a confusing sentence about this on the Ricoh page about it.) Or a RAW file, but not a Bayer RAW file? Will we able to use the results with the usual programs (Lightroom, etc) that work with RAW files and be able to have all the usual adjustments available to us? I'd love this technology, but at what cost in post-processing?
My fear now is that the non-JPEG option will not be Linear DNG. But instead will be 4 separate raw files that need the Pentax utility to process them.
Originally posted by quant2325 1) The files shouldn't be much bigger, if at all. This is a completely different way of doing this than Olympus. You will get 48MP (or whatever) effective resolution without massive files.
2) The K-3II obviously becomes the sharpest APS-C camera on the market, assuming you are a landscape photographer (use a tripod). Your photos of the next Yosemite vacation (or macro of a still bug) will have enough sharpness to put large posters on your wall.
3) This technology will be massive for the pros once it hits the FF and medium format Pentax cameras. They use a tripod anyway, so using this technology for landscape photography is no big deal.
I assume the total size of the non-JPEG option (whether it is true raw or Linear DNG) will be about 3 to 4 times the size of a single raw file. Why not?
Originally posted by quant2325 Ricoh is taking four pixels of each Bayer color filter array cell--twice as many green than blue or red--and aligning them (like one on top of the other). The file should have the same number of pixels. The difference is that each pixel now has full G,R and B data. This is completely different than the Olympus approach. Ricoh is not adding more cells.
True. They will supply 3 or 4 times as much data for each pixel, without increasing the number of pixels.
Originally posted by Gimbal Yes, the same number of pixels, but three times as much data for every pixel. Thus the file will take three times as much space.
That is my guess. Or if they provide 4 unprocessed raw files, the total size may be 4 times the normal raw file size.
Originally posted by rawr We assume. But lets see an actual pixel-shifted DNG to test that assumption.
Hopefully the guys who did the Ricoh sample pix were shooting RAW+JPEG. Maybe Ricoh will release the DNG's that match the JPEGs.
I hope they are DNGs, but fear they will not be.
I responded earlier saying I thought the camera would output a Linear DNG file as the non-JPEG option. I fear that it won't, but instead will be 4 separate raw files that need the Pentax utility to process them.
Could they avoid outputting 3 or 4 times as much data as a single raw file? Perhaps, with some clever (and somewhat destructive) compression that plays games with the relative values at a pixel and uses the differences. (I'm out of my depth here!) But to get the maximum benefit from the technology, I can't see how they can avoid putting 3 or 4 times as much data on the card.
We need more information! Waiting ... waiting ...!
