  • If I wanted to buy a classic car I'd buy an Aston Martin DB4 or a Ferrari 250GT. Those cars are the epitome of "Classic". But I'd sound like a real moron referring to them as either the "Aston ...
  • Yeah, but you have to admit that it's freakin' AMAZING that (according to you guys) since the release of the D810, every Nikon lens can suddenly outperform the AA filter-less sensor at pretty much ...
  • Well, not really. With the exception of mirror lock-up, can't anything that can be changed via the mode dial on the Nikon can also be changed by the top buttons on the Canon? And can't everything ...
  • That shouldn't be difficult for you to prove. Just point out where unsharpened RAW files have noticeable aliasing, and we'll all be on the same page. Or were you talking about the night time photo ...

  • Blurring and resizing will just make the fainter twigs melt into the background. I'm working, and don't have time for uploading right now. I've used what I described above as the basis for a few ...
  • The way I see it, is that the biggest problem you'd have with resizing that image is that the very thin branches and twigs are going to get lost and break up (become aliased). O.k, just try this as ...
  • Replied in Ooops!
    I just realised the larger image was there. I was looking at the "large" gallery version, which is the 1.7mp one. There's relatively little aliasing in the full size image, but the scene is not a ...
  • It means that having an AA filter or not makes no difference to this image. A 200 f/2 L would probably record about the same amount of detail on a 5DIII, so if you're having problems here, you'd ...
  • It's not WORTH putting any text HERE!
  • Nope. I didn't perform any software up sampling on your image. I just looked at it in PS at 400% and screen captured the result. So it's pixel perfect. Resampling doesn't add big halos. Try again, ...
  • Ok. How about I just debunk your BS processing? Remember that great photo you showed with ALL THAT ALIASING that you arrived at by just resampling DPRs original image using Laczos resampling in ...

  • Wrong. Parts of this image are higher frequency than any of the sensors can accurately capture. EVERYTHING is a compromise. Oh, so it's o.k for you to scour the internet for images that ...
  • Well, the problem with the image you posted there is that it was taken with a Nikon 70-200 f/2.8 at f/7.1, a lens that doesn't get very close to the limits of the D810 resolving ability anywhere ...
  • How about you look at these photos (where the 645D is the reference image)... and explain to me why the 5DIII with it's supposedly better AA filter produces more moire than with the D800 or the ...

  • Right, so why does your down sampled image have big fat sharpening halos around every high contrast area? Why do you have RGB values way beyond what's in the original file? I'll tell you why… IT'S ...
  • It's really just a matter of where moire (and to a lesser extent aliasing) is produced. An area of high detail that produces moire on the old Nikon 12mp FF sensors won't produce moire on the Canon ...
  • I think that your choice of lenses should be the deciding factor. The 5DIII and D800E are both good enough that you won't be disappointed in either. The same cannot really be said for lenses. ...
