Hi, so I've got an E-M1 kit. I've been using Lightroom 5 (recently 6) import into RAW and I've been generally happy with it. I noticed the noise was a bit high but I put that down to my default import profile being at 25 sharpness. Anyway I've read all about Olympus Viewer 3 being excellent (including Robin Wong and forums here) so I thought I'd give it a go - these are pics taken on 75mm 1.8 at 1/50sec shutter and ISO 3200 focused on nearest eye. My default lightroom profile: - Everything 0 except: - Sharpness 25 / Radius 1.0 / Detail 25 / Masking 0 - Camera Calibration Process 2012 (Current) Profile Camera Vivid Note: The in-camera picture mode is also Vivid on the camera if that makes a different to Olympus settings. I may switch to Natural with a slight boost in saturation in the future though What I've done: 1. Imported RAW into Lightroom (I use "copy" rather than "Copy as DNG" - unsure what the difference is) 2. Imported same RAW into Olympus Viewer 3, exported as 16Bit TIFF, then imported into Lightroom 3. Export both at JPG for Resize to fit 1024 pixels with Sharpen for Screen Amount Standard with JPG quality at 100% 4. Export both at 100% crop 1. Lightroom export 2. OV3 16Bit Tiff in Lightroom export 3. Lightroom export with Natural camera profile 4. Lightroom export with Adobe standard camera profile (note the shirt) 3. 100% Crop Lightroom 4. 100% Crop OV3 16 Bit Tiff in Lightroom 5. 100% Crop Lightroom with sharpness at 0 My conclusion: 1. The colours are very slightly increased in saturation in the lightroom pic on Vivid. compared to OV3 16Bit Tiff but could easily be dialed back a notch. 2. Natural profile doesn't seem able to replicate OV3 16Bit Tiff exactly and Adobe Standard is way off. 3. OV3 seems to go bonkers with the noise reduction and turns fine detail into mush. I've noticed this at 100% in other images also. Even with lightroom sharpness at 0, it still maintains more detail than OV3 (look under the eyelids). T Based on this - I can't really see much benefit in using OV3 16Bit Tiff export into lightroom. 1. The noise reduction on OV3 is very high, turning fine detail smooth. I could always set the default profile in lightroom to have increased noise reduction in lightroom if I wanted as that is currently on 0. I'd prefer to have control over noise reduction rather than OV3 doing it automatically and reducing detail. 2. Whilst I'll agree that perhaps the colours look the best on OV3 16Bit Tiff, it's so marginal. I could probably set the default profile on Vivid with a -5 increase in saturation/vibrance or on Natural with a +5 increase on saturation/vibrance and get similar result. Does anyone have much thoughts or have I missed something? Side note: I'd love to know what the general consensus is for Lightroom 6 default profiles Side note 2: Does the 75mm 1.8 look sharp? It's a second hand copy I bought so interested to know if it looks as tack sharp as the 75mm is meant to be.
