(What's RPP?) That's 64MPx, all right. A 16bit TIFF would fill 128 MB before compression. But there is some magic going on in the transformations. Each set of four shots produces something like 3x12 bits of good color information at each of the original pixel sites, since the Bayer filter interpolation is not needed any more. The second four shots do the same, but now we have 32 MPx of this lovely color data on a lattice which is tilted at 45 degrees to the original orientation and has to be rotated back for display. (Take a bit of square-ruled paper, put a dot into the middle of each square and you'll see that you have made a new square array, tilted at 45 degrees.)The HR ORF file that I processed with RPP gave a 9280x6938 16 bit tiff file.
9,280 x 6,938 = 64,384,640 MP :clap:The HR ORF file that I processed with RPP gave a 9280x6938 16 bit tiff file.

So they map it back onto a set of "virtual" pixels with half the original spacing but not rotated. There are 64M of these virtual pixels. But how do you suppose the color information is encoded? It would be a shame to turn the 36 bits back into just 16 bits altogether for the three colors. We don't really have the spatial resolution that the 64MPx array of pixels implies, but we have more color information. It's magic.
Maybe the E-M1 Mk ii will take 16 shots and capture all this resolution? Or Sony, or Pentax, which have to respond to this challenge.
