+Tek Syndicate just published one in video and they're pretty enthusiasts about the results 🙂
A tip about converter software: +Albert Manduca, who shows his experience with RAW editing uses +Adobe Lightroom which is great as it's one of the software that implement all the DNG capabilities I used during profiling. Mainly: * Color calibration * Noise profiling * Lens vignetting correction and sensor color uniformity
DNG files are the RAW sensor data plus metadata that describe shooting conditions and how to transform what the sensor sees into a corrected image representing colors as they are. Compared to proprietary RAW formats, DNG is self-describing.
Smartphones' captures require more correction than other cameras due to their physical constrains. Some converters support DNG but not all its features. Typically, noise, vignette or color uniformity won't be corrected as expected, color conversion incomplete, exposure compensation not applied so be sure to use a fully fledged RAW editor!
By the way, did anyone made a comparison with a Lumia DNG?
In my last post, I was talking about flat field correction, a technique that allows to fix lens vignetting and associated lens+sensor color cast.
Here's a first result 🙂
This is the same picture of an uniform white reference, with contrast +100 in Lighroom to emphasis the difference:
– Without DNG correction – Without DNG correction but with Lighroom built-in Lens Vignetting tool adjusted to best settings possible – With DNG flat-field correction defined in the DNG file itself: to the user, it's like vignetting or color cast were never here!
Yesterday I flooded Michael for hours with details and explanations. Talking about projects I'm working on with passion to improve user experience on mobile in very specific areas. Kudos to him for managing to write an article out of it 🙂
I just started at +Cyanogen so there's a lot to learn. I'll do my best to transform R&D into concrete products, and there's no other place to make this real in connection with the developer community and a large and enthusiastic users base.
Feel free to drop any question, I'll do my best to answer here with what I know.
