Oh for some compact rangefinder-style MF lenses

Just don't upload them to Facebook or Twitter because they'll be downsized to ~1,500 pixels... The only sensible built-in upload option for Panorama's is Flickr.

In reply to:

DUSTY LENS: I like this new system .
It seems to be very easy to use for comparisons between Cameras .

I wonder if something like this or even this same system could be used on some most desired lenses also , for comparisons without the use of the camera body , and instead using a standard body or digital back in order to eliminate the variability of the bodies and sensors .

Seems like far too much to ask though .

What a lame waste of resource, we achieve the same at dpreview with a cove, soft box strobe and umbrella strobe! He spent more time in Photoshop than shooting.

Phil Askey: There's no Android API for reading raw pixels from the sensor, you always get a pre-processed 'bitmap' which (as you stated) has been demosaiced, gamma corrected and white balanced (and whatever else the manufacturer's camera driver does to the data on the way through). On a rooted phone it may be possible to access the low-level camera device and read data off that way, hence it's more likely that IF a phone camera ever supports RAW it'll come via the phone manufacturer's own camera app or a change in the Android API.

Jaggr - if you read the API properly they are MISUSING the word RAW, it's still demosaiced.

Well of course the "hardware" and in fact Android sees the RAW data but it's demosaiced in a compiled C library which has no public interface for developers to "step in" and access the data before it becomes demosaiced. Like I said above the best bet here is that Google (Android) provide developers with a fourth option when requesting the frame buffer - "RAW"

Seems a bit pointless to process RAW files from a camera on a relatively low-powered and battery driven device like an Android device.

And yes, here we're talking about the original story, an app which purports to capture "RAW" data from the sensor in the same way a camera does.

Yes, from a quick dive into iOS framework I can see no way to get image data that hasn't already been demosaiced (you can certainly get "uncompressed" data, but not RAW photosite level values).

In reply to:

Lan: What you've basically debunked is Adobe's DNG format...

Not at all, DNG typically means RAW (as in the photosite level values untouched and unprocessed), but in this case it appears the developer is using DNG to "trick" users into thinking it's truly RAW.

Just by way of a follow-up, the only "formats" officially supported by the Android API (which means without accessing the camera device directly with root) are NV21 (YUV), RGB_565 (16-bits per pixel) and JPEG.

Great to see lens reviews make a return to dpreview, to see photographs of Tower Bridge and the surrounding area again, the first review reads well and has lots of good technical data. Kudos Andy and the rest of the team.

AbrasiveReducer: I was going to say the same thing. It says "Click here to read our 8-page in depth preview", I click and it says "Click to read our preview". Not a big deal but I have never understood this two-stage process.

Well mostly because in a few weeks time when that story has floated off the bottom of the front page news feed it will be primarily accessed from search engines which will come into the news story page.
