  • Replied in Oh, dear
    I'm glad you're keeping an open mind on the topic. Actually, you can often locate the original source of the image by just dragging and dropping the image into Google image search.  Look up ...
  • Replied in Please stop
    If you claimed that 2+2=5 and Leonard wrote: "It's really not a good idea for you to be making pronouncements about arithmetic since it is clear that your are not educated in this area." would ...
  • Hey, that means I may be losing my mind but not my eyesight! The last image I struggled with was one of Crater Lake bathed in deep shadows. The lake itself is exceedingly blue/green to begin with ...
  • An excellent response, but I'd maybe qualify that last sentence a bit. Field curvature problems are common in lenses, to be sure; but there are plenty of "real world" use cases where you want that ...
  • Interesting.  And, yes, I've also detected differences a day later as well, but I always question my perceptual memory and wonder whether I like them more the next day because I've gotten used to ...
  • Excellent article, Andrew.  Thanks for writing it and posting about it over here.  One "darkness" symptom that you don't specifically address in the article but that I find myself sometimes guilty ...
  • Replied in EM5 II
    This is a really interesting point. When the HiRes reaches its limit, it fails gracefully. When an AA-less camera like the D810 reaches it limit (single frame), it fails gracelessly sometimes ...
  • Sigh. I explained in the first posting what I did and how the comparison was to the reference sRGB color settings for the Macbeth chart. The two strips overlaid on the reference colors were from ...
  • The topic being discussed was the color accuracy of the Sigmas. I only included the D800 as a "control" that you would be familiar with, so your criticism of the Nikon's default in-camera color ...
  • Nice try, but these are from the camera-generated jpegs. Why? In an apparently futile attempt to educate you.
  • Well, then, that's not a very fair fight! The TIFFs are already demosaiced, white balanced and gamma corrected when they're imported into LR.  Any subsequent attempts to do highlight recovery will ...
  • There are numerous strategies to locally attack the problem of moire.  You've identified one above.  In PS proper I sometimes use one of the content aware tools - healing brush or patch - to ...
  • The amount of moire will vary from shot to shot, and whether it's a problem for any given photographer will very much depend on what the photographer shoots. Regardless, there's no question that ...
  • Yes, OV3 applies more sharpening by default than does LR/ACR. I would be surprised if that's truly the case. After all, they're both working from the same raw data and if the data is there to begin ...
  • Fine. Call it whatever you want and you can continue discussing with SpinOne. My real point here is that you can actually do something very similar in LR and ACR (and other raw processors for that ...
  • I think your dispute with SpinOne is largely a semantic one. Yes, OV3 applies the various tone and color controls set in-camera to your raw file by default when it's processed. SpinOne wasnt ...
  • Actually, at base ISO you CAN get your free lunch. It's only as you start moving up in ISO that read noise starts to become more of a factor and larger (but fewer) pixels beats more (but smaller) ...
  • Replied in Whoops...
    I just realized that the OP wasn't talking about shooting murals as subjects, but printing up to mural size.  Obviously a different use case than the one I was discussing, but the relative pros ...
  • The D810 will be worst with respect to moire and aliasing artifacts. The Sigma will be better because it doesn't introduce moire from demosaicing.  However, it will still have the inherent moire ...
  • I agree that it's a weird workflow.  Always raises exposure (why not add real exposure comp in camera?). Then he moves into ACDSee for additional basic adjustments that could have been done in ...
