This post isn't probably pertinent to every shot captured with the ETTR technique where a small adjustment to the exposure slider is all that's needed to pull the image back. However I've been playing around with the ETTR technique over the past week or two since reading Petka Pokka's original article and discussion on the threads here (thanks guys again for the fantastic original thread). My problem is that for all intents and purposes the primary reason that I use my E-M1 , over pretty much every other systems etc.... is down to how I view IQ. I shoot Olympus for the colour signature. I love it!. It's not for everybody and I've friends who hate it, but I love it so my ultimate goal is to keep the Olympus colour signature and maximise the amount of information captured in my Raw files! Are these two things mutually exclusive though.... The ETTR technique is great, but heavily dependant on a good post processing workflow - however that means we are at the mercy of our Raw convertors.... LR + great highlight/Shadow recovery + pretty good colour profiles in 5.3 (but still too much red and not quite the same as Olympus Viewer 3). + noise reduction is pretty good - lens profile corrections are only average. - demosaicing algorithm doesn't look to pull quite as much detail as photoninja or Dxo Optics Pro. - Color profile is close to giving Olympus colours but skin tones are not exactly the same - perhaps a little too much red. DXO Optics + good shadow recovery / highlight recovery - not quite as good as LR, but automatic 'smart light' generally does a good job of opening up the dynamic range. + Great demosaicing algorithm that pulls lots of detail + great sharpening profiles based on each individual lens + phenominal noise control -- crap colours with supplied default DXO standard profile and Olympus camera body profiles compared to the latest LR5.3 and more importantly OV3. - red channels are oversaturated but possible to get great skin tones if you have the patience to massage the red channels in post if not using OOC jpeg. Olympus Viewer 3 + Best/great demosaicing algorithm looks to pull the most amount of real detail from the Raw files. + Opening the a raw file in OV3 the Default sharpening ( setting of 0) looks to be pretty good without requiring any other raw presharpening. +++ get to keep the Oly colours - Highlight/shadow recovery is crap. Not so great for working with ETTR in post if you have deliberately over exposed to the right by a stop and a half. - Noise algorithms are crap and smudge details. I leave this to off regardless of ISO as the incamera noise settings are far superior to what OV3 software does for noise control. From reading around exporting a 16bit tiff from OV3 ends up truncating a lot of hidden highlight data close to and around pure white. If you shoot with the ETTR technique and also keep the Oly color signature, how are you accomplishing this with OV3 / LR / DXO / Photoninja (I got a mail from DXO to say that colour profilesspecific for the E-M1 are coming in jan so this may be a moot point in a few weeks).? Thanks, Tom.
