I wonder how well and fully implemented the DNG spec is on the reader. Hopefully it's not differing much or at all from Adobe reference SDK. I say that because there's a few key aspects crucial for color calibration and accuracy missing from the regular Android DNGCreator class introduced in Lollipop.
Today is a big day for Snapseed users! Snapseed 2.1 brings RAW photo editing to your Android device.
Traditionally, shooting and editing RAW photos has been the domain of DSLR cameras and desktop software. But with the RAW capabilities that were added to Android 5 last year, RAW is now becoming important for mobile photography, too.
Snapseed now allows you to edit those RAW photos in the DNG file format right on your mobile device. You can also edit DNGs that were shot on cameras or converted from other RAW formats.
A photo in RAW format preserves all of the original data that was captured by the camera. This allows you to perform edits – such as recovering blown-out highlights – that are impossible with the more commonly used JPEG format. Check out the photos for an example of the details that RAW editing with Snapseed 2.1 can bring out in an image.
In addition to RAW editing, we have made some slight polishes throughout the app to make it easier to navigate, so give it a try!
It seems compact enough to be in your pocket when you'll get out: more than Sony QX smart lenses although at the expense of a zoom lens.
+DxO is being dishonest by using the DSLR comparison we read too often: "The power of a DSLR" They argue that the DXOMark sensor score is "Up to 85" which is slightly higher than as a last-gen Sony 1.5x crop APS-C sensor, despite the DxO One use a Sony 1" sensor.
Actually this is is a theoretical score calculated by using computational photography blending multiple exposures, comparing apple and oranges. So.. yeah, there's that.
It's good to see new cameras implementing computational photography methods however, including for RAW!
The website announce 650€ to pre-order it, then tell me it will be available only in the US for now (I'm in France)
– Both lack flat-field correction – Both provide incomplete matrix-only color profiling: no DCP – Neither use compression – HTC One M9 DNG is 10 bit stored in 16bit uncompressed data: 39MB per 20 Mpixel image. – LG G4 DNG is 10 bit stored uncompressed, 20MB per 16 Mpixel image – Both have non-optimal noise profiling settings: HTC One M9 set noise reduction too high and LG G4 lacks noise profiling entierly.
Notes on flat-field correction: Mobile camera modules require such correction to correct both vignetting and color cast (like pink spot / greenish or blueish corners). HTC One M9 requires less correction than the LG G4. It is only possible to compensate for light fall-off, in RAW image editors, not color cast. As a result, the color cast in corners is essentially non-fixable.
Attached: the #LGG4 DNG sample provided by +Colby Brown rendered in Lightroom with only modification an increased contrast and exposure slightly, to make both vignetting and color cast more obvious.
The least I can say is that there's room for improvement, both DNG implementation being non-optimized and incomplete.
Android Camera2 API promises to revolution digital imaging on smartphones or altogether with advanced capture and processing capabilities that have never been accessible to third party applications before.
Some of what becomes possible is manual controls, computational photography, RAW #DNG capture, full control over video recording, custom image processing. Limits are few.
Here's an analysis on how much of this new API is supported by the #Lollipop devices released during #MWC15 , including the highly anticipated Samsung Galaxy S6 and HTC One M9 flagships.
+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?
