  • I'd say "yes and no" to the improvement in easiness. Multishot alignment in processing can be somewhat problematic but one shot can present DR issues to deal with (even for a camera with good DR ...
  • Of course. My comment is mostly about the implication that similar PDR scores between the two cameras means no real-world difference in noise performance (typically a concern in so-called "high ...
  • The elephant in the room here isn't the respective PDR scores (and whether the D750 is representative of current generation cameras) but, rather, the effect of different sensor sizes (and ...
  • It's caused by the physical aperture/opening interfering with light being directed through the lens. This is what I believe you're referring to as "actual aperture." Now you're talking about the ...
  • There is no computational alignment done for in-camera HDR shots. However, image stabilization is still available in HDR mode to counter random handholding movement. Hence, camera movement blur is ...
  • The shots were saved in Photoshop as PNGs (to avoid compression artifacts). I'm not sure if this is just a Photoshop thing or if the PNG format limits what can be saved as metadata, but either way ...
  • Light was consistent but mixed artificial (mostly halogen) with some incidental daylight. There was a big difference in shutter speed (obviously), so perhaps it had something to do with the ...
  • Created discussion thread Shooting f/16 on mFT...Oh NO!?!
    In a couple of recent threads here discussing diffraction "limits" of different camera formats some participants claimed that diffraction softening is overblown even at large f-numbers like f/16 ...
  • You may be referring to this thread. However, if you read deep enough into it you will see that there really is no G9 advantage when similar amounts of sharpening are applied. It's just that the G9 ...
  • Nice shot. I also generally opt for exposure bracketing instead of trying to do it all with one shot (often requiring a ND filter). The problem with water falls is usually not just about ...
  • Here's a suggestion for you: smear some Vicks VapoRub on front element of your lenses and sleep next to them. You'll sleep better and diffraction will instantly become an undetectable and, ...
  • Yes, with one important exception to note. See below. There are two principle contributions to blur - diffraction and aggregated effects of various aberrations. These effects, added together, are ...
  • A well exposed image at base ISO, especially if you're not lifting shadows or overall brightness in processing, isn't likely to need global noise reduction. However, there's no absolute answer ...
  • I copied the files into PS and took a look. There is more noise reduction applied in the OOC JPEG. This is most visible in the blue shorts and the fence posts. To me, though, it's not a shot that ...
  • I can certainly understand the challenges posed by changing conditions. That's the glorious frustration of nature photography. What I don't really get, though, is the need for menu-diving. If the ...
  • Why wasn't this a good use case for shutter priority plus auto-iso? Since you were already prepared to shoot wide open (f4 on your 300mm) and your big concern was keeping shutter speed up, shutter ...
  • Well stated. I'm bookmarking this exchange as evidence for the next time someone argues that the exposure triangle is a helpful heuristic for learning how to expose properly.
  • Replied in Equivalent ISO
    On the contrary, going down the equivalence path to identify where one system is compromised relative to another is very useful in the real world because it gives you a basis for making a rational ...
  • Replied in Equivalent ISO
    Or put another way, since no existing mFT camera is capable of shooting at ISO 25, this particular scenario is outside of the mFT cameras' equivalence envelope and the advantage goes to the camera ...
  • The D700 "gave nicer files" probably because the playing field was not "level" - i.e., not equivalent in a way that benefitted the D700. In a number of photographic use cases, that's unavoidable ...
