  • Created discussions HDR prints
    Some LCD displays can increase their apparent DR by modulating the intensity of the backlight within a spatially limited area. This approach has pros and cons - parts of the scene can be made far ...
  • If the sensor seriously out-resolves a state-of-the-art lens, how many photons are there typically per sensel, and how easy is it to do deconvolution at that kind of granularity? -h
  • This is really strange. Imagine the facepalms in the audio community if manufacturers of professional audio recorders did not allow the user to monitor recording levels as effecting internal noise ...
  • Will the AF accuracy scale with sensel size? It seems plausible that a larger sensor of 4.x micron sensels might allow for more relaxed AF tolerance than a smaller sensor of 4.x micron sensels? -h
  • Replied in Sharpening
    My bad. This was the URL that I was thinking about, reply#76 " the D800 shows a limiting resolution of 93.9 cycles/mm or 92.0% of Nyquist, and the D800E shows a limiting resolution of 94.9 ...
  • I don't have an aa-filter-less camera myself, but I believe that somewhere in the links below, there is a quote by Bart Vanderwolf about the D800E having 1-2% more resolution than the D800 after ...
  • @Just a Photographer:
    At what point will we hit the theoretical "diffraction wall"? There are estimates of 288 MP - for APS-C (!):

  • @Just a Photographer:
    Yes, really. You will find out if you try to read up on the subject.

    I probably won't buy the 5Ds, but not due to some home-made faulty theory on resolution that you offer,...

    This is actually the best advice that you have given so far, and that is exactly what I will do. Being able to do a google...

    I am not falling for anything. I am using my engineering education and good references in order to...

  • Taking multiple pictures might not be possible due to scene movement. But even for scenes that allows it, it is nearly always a pain that I would rather not have. Why would I want to do extra ...
  • @Just a photographer:
    In fact, every photography, shot at every aperture using any sensel density will have decreased sharpness due to diffraction.

    I suggest that you either cut down on the condescending tone or just accept that people over here generally will classify you as just another internet fool.

  • I don't get your reasoning here. You have needed DR enough to do multiple exposures in order to extend the DR of some camera, yet you see no reason for being able to do the same in a single shot? T ...
  • Thank your for that link. So graduated ND-filters cannot be completely substituted by HDR techniques. If only that ND-filter was structured and scene-dependent (kind of an optical AGC), you could ...
  • Translated: We are now applying noise-reduction to our raw files :-) -h
  • Doing 24 MP in camera will not improve image quality compared to recording at the native sensor resolution the processing optimally in a raw developer. I think that the 5Ds(r) may do well in a ...
  • True. But it seems that flare works in slightly unpredictable ways, is different for different lenses (and slight camera movements), and even significant visible flare may or may not kill the ...
