  • Kudos to Richard and the others who helped him put together this piece that does an excellent job of explaining a difficult topic. Would it be too much to ask for a follow-on article about the...

  • I have never once on any of my ILCs used the video recording feature. Not once. It's just not why I drag my ILCs and lenses around with me. Although video is of no use to me, I wouldn't presume to ...
  • At B&H the EM1ii (body only) is a whopping $2.00 more expensive than the GH5 (body only). What a rip-off! P.S. For some of us pro-grade video is "useless" and HiRes is a really nice feature "for ...
  • Not very well stated. If you're over the Nyquist limit for the sensor, you're going to get nothing but aliasing/moire. You will get no "greater linear resolution" at all (let alone 50% or whatever ...
  • Correct. Anti-aliasing filters behave in a highly consistent way on all high frequency signal (finest detail) across the image. The visible impact is minimal even at 100% magnification of the ...
  • No argument on that. I posted the same DR info (referencing Bill Claff's results) and the same conclusion that the explanation must be elsewhere.
  • If he's shooting raw and doing landscape work and postprocessing in Photoshop anyway, the best strategy is to exposure bracket and stack. It's not necessary to use ugly HDR tools either to attack ...
  • Well, when it comes to photography the devilish detail I'm worried about is in the images and NOT in the words of some misguided six-year-old article. If you want the formulas and technical ...
  • That claim was presented in this article on LuLa. Obviously, there were no mFT sensors with more than 12mp at that time. Nevertheless, if the claim is correct we should see no real improvement in ...
  • You're definitely on the right track now. Also check out the hue/saturation adjustment layer tool. The selective color adjustment allows you to manipulate six primary/secondary colors in a rather ...
  • Replied in Wrong
    As others have noted the Fuji sensors of that era were uniquely designed with different sized sensels specifically to increase DR. That sensor design was long ago abandoned by Fuji. Far more ...
  • As I read it, the gist of Brian's response relates to Rishi's comment that smaller sensors are "more demanding" simply because they samples the lens at more lines per mm. Brian is pointing to the ...
  • False premise. The fullframe manufacturers have also moved to complex and expensive lens designs as well. Check out the Sigma 50mm f/1.4 and the Nikon 58mm f/1.4, and the Canon 50mm f/1.2L. And, ...
  • On the one hand you have Rishi Sanyal, a well-intentioned "technical editor" of a website whose credentials are a love of photography and a PhD in a field unrelated to optics or engineering. On ...
  • It's a function of the raw processor, but call it "JPEG engine" if you prefer. No, not at all. In my experience, I've found it relatively easy to deal with color moire (even easier now with ...
  • It can't fix moire that's in the processed image itself. The only thing it can do is change the frequency at which any screen-based moire will be visible. Remember, moire can be introduced at any ...
  • Unfortunately, there is no free lunch when it comes to fixing moire/aliasing artifacts. The Oly raw engine is pretty aggressive (and pretty successful) at reducing color moire when compared to ...
  • But this image shows classic moire/artifacting in the exact conditions you'd expect it to occur. It doesn't look like the rainbowing effect I've seen from polarization.
  • 25mp and 50mp refer to the total number of pixels in the JPEG HiRes images produced in-camera. Neither relates to file size. 80mp refers to the total number of pixels generated from a raw HiRes ...
  • Replied in Calibrate
    Monitor miscalibration is certainly one common problem, but calibrating your monitor with a calibration tool is far from being a panacea for all of the differences in prints and monitor display. ...
