Re: Unsharp and with a DR problem, too

There is either motion blur or missed focus on this shot.

Additionally the camera should have exposed for the highlights (the sky) and the shadows should have been recovered.

aka: HDR Tone Mapping post-processing... yes, lots of folks shooting like that approach.

but, you forget, 5DMkIII already has HDR built-in, besides, one has to assume one even want an HDR look to begin with, this is what 'shadow recovery' really is in effect, even though most won't admit it, highlights remain blown even for HDR (if you have 'any' white 'anywhere', it's blown, period.)

With these two flaws (unsharp and blown skies) I would hardly call this photo a keeper.

an HDR 'shadow recovered' pp, does not mean it's a keeper, some folks want to preserve a higher contrast look, such as grey skies looking 'light grey to white'.

ditto for shadows. one often can go too far and end up with NO shadows, which is equally bizarre to look at. so 'shadow recovery' is ultimately a relative 'desired' attribute rather than an absolute one.

so far, doing any pp is already an indication that all dSLR sensors are flawed, because NONE capture lit sceneries as well as our eyes naturally perceive them, that is, zero shadow clipping, and zero highlight clipping all caught within a single shot with NO pp.

by doing massive pp, one is also in effect introducing an artificial ISO 'gain'; this is precisely the limitation of all current dSLR mono-ISO image capture sensors today. I've advocated that newer systems offer us mulit-ISO image capture via multi-ISO control on any DR curve of a dSLR system, and preview it 'live' in realtime, so we can get 'all details' (at a creative level by choice) desired, in a SINGLE shot with zero pp required.

in the meantime, so called 'shadow recovery' and HDR 'tone mapping' of imperfect single shots, or worse, multiple exposures, etc, etc. 'make do' for now until then. and so, ultimately, there isn't a dSLR out there that isn't Natural Full DR flawed.
