    I also have that book. Takes your breath away. My son's favorite bed-time book with me when he was 8-10 yrs old. A long time ago.
  • The 80M "pixels" in a hi-res image are not 80M separate locations in the image plane, as you are stacking aligned measurements taken through the three R/G/B filters. In a single-exposure Raw file, ...
  • I've read a fair amount about the photography that was done during the lunar missions. The cross-hatches were there to calibrate distances and orientations between shots. I've never seen it ...
  • Replied in Sound stage
    Yes, impedance-matching is important.
  • Replied in Sound stage
    The secondary reflections from the hall inform your brain about where precisely the sound is coming from. It is critically dependent on the microphone placement, how the material is mixed down, the ...
  • But only if you use oxygen-free copper. Otherwise the sound is timid, and the sound stage is dark.
  • This comparison illustrates the improvement in color rendition. "This becomes clearly visible in the final crops, where despite the two image's similar pixel counts, the Olympus image is able to ...
  • Agreed that "resolution" is actually a complex term and insufficiently defined here. Which is why I talk about how many unique sites data is gathered from. The key point is that high-res mode ...
  • You need to understand each step before moving on to the next. 1) If your sensor has 20M pixels, you are gathering data from 20M unique sites. 2) The sensor has a Bayer filter, so the light ...
  • "Clean" speaker cables for "crisp" sound. Or the other way around, or whatever.
  • 4 exposures with 1-pixel offsets (20M sites), 4 exposures with 1/2-pixel offsets (20M additional sites). There is a Bayer filter, so each exposure only captures one of R/G/B at each site. When I ...
  • I was responding to your incorrect characterization of what I was saying. Since these sensors are collecting only partial data at each site, what you are getting is very partial data from 20M ...
  • No. The standard exposure collects data from 20M sites. The pixel-shift exposures gather (more) data from 40M sites.
  • There is no "luminance" cell, only R/G/B. Luminance is generated post-R/G/B capture.
  • Yes, 2 x 1/2 = 1 (not being flippant).
  • It's unallocated disk space. You can set it in Disk Management. I set it at 10%.
  • I'm talking raw data. Works the same way with Olympus as with Panasonic. A JPEG engine can generate whatever resolution you want -- 40MP, 50 MP, less or more. Just a matter of how much ...
  • My understanding is that 4 of the exposures are full-pixel shifts that overlap the different colors; so color rendition improves but not resolution. The other 4 exposures are 1/2-pixel shifts, with ...
  • Replied in SSD life
    I just checked Samsung SSD Magician: I've written 116 TB on my 500 GB Samsung 850 PRO SSD; 230x. This is my C-drive, OS, applications, previews and cache, and all the data files are on my HDD ...
