Joe Pineapples II's recent activity

  • I guess you don’t like titles (me neither) but if you used the date or location or something rather than just “Untitled” it would make it easier to sort out the threads in the forum. J.
  • A Leica Q cropped to 135 mm FoV would be equivalent to a 1 MP, 1/1.8” sensor camera - like a $20 toy camera. The Sony RX1R II is more compact, and the 35 mm lens might be a bit more versatile; but ...
  • Replied in Dandelion
    Not at all. Flowers are a very difficult subject to photograph well. Experiment with different points of view, and take great care with backgrounds, exposure, and lighting. It is easy to saturate ...
  • It is interesting that there seems to be more aliasing visible with the Canon lens. It could simply be the high resolution of the Canon lens, but it makes me wonder if the camera is doing some ...
  • Some scantily-clad girls around the pool would be nice... just so we could compare skin tones, of course. :-) J.
  • I am strictly a bluffer, not an expert, but I attended a lecture by Prof Mandelbrot in the 1980s, and partly inspired by that, I went on to study classical mechanics and the connection between ...
  • A better antenna at one end helps the link in both directions. That’s why NASA has 70 m dishes for communicating with its spacecraft. J.
  • There are two different effects that people call "distortion". There is the forced perspective caused by the wide angle of view. This is unavoidable, and is just a function of the relative ...
  • Replied in Oh my!
    That’s the curious thing about electromagnetism. Electricity, magnetism, and optics were studied from ancient times as completely seperate phenomena until the discovery by Oersted that electricity ...
  • My philosophy would be to capture all the information I can (the same as photographing a natural scene) and then process to get the output I wanted. J.
  • That's where, in theory, the Pentax K-1 with its pixel shift more would be ideal. Then you get the full 36 MP resolution with RGB coverage at each pixel, effectively avoiding the problems of Bayer ...
  • Is the girl in black another of your students? If not, you should recruit her! J.
  • A cute puppy! The 35 mm f/1.4 looks nice, but the 23 / 60 combination seems to reflect the original CL concept so nicely. J.
  • In calculating etendue, dΩ is the solid angle . J.
  • I like the 23 mm a lot. To me it has the real Summicron look: low distortion and uniform high quality across the whole image - a classic Leica lens. How’s the out-of-focus blur wide open? J.
  • The camera sets up its own hot spot, and your device connects to that. The range will be limited either by the limited power of the camera’s WiFi, or by interference from stronger WiFi routers ...
  • Replied in Really?
    AFAIK people offering criticism of a photograph don't normally put up an alternative photograph and say "I think this is better". Nor do they just say "I love it" or "I hate it". They usually ...
  • Replied in Oh, why ...
    My understanding is that the sky is bright at night, but only if your camera is sensitive to wavelengths around 5 cm... J.
  • Replied in Oh, why ...
    If the infinite number of point sources is correct, why is the sky dark at night? J. :-)
