Try using a tripod and use lumia camera or 1shot, i find proshot a bit crap compared to the other two but they look nice, did you use raw or high res?
Add filters to your Lumia 1020 (or Nokia 808)
Using ProShot, I had the "34MP" output resolution (16:9 ratio) with 10.0x live digital zoom. Here's the tricky part - 34MP is the output of the sensor itself without digital zooming, where any form of digital zooming would be taking a smaller (and lower resolution) portion out of that 34MP at 16:9 aspect ratio. However, ProShot still gave me a "34MP" image even if it was digitally zoomed in at 10.0x magnification. I've talked to the developer about this a few months back and he said that the app intentionally saves a larger version of the cropped area of the sensor as if it was using the entire sensor was being used. So, if my digital zooming was only using (for example) a 5-MP section of the sensor, ProShot will still save the resulting 5-MP photo as a 34-MP photo, similar to simply increasing the resolution of an image in PhotoShop without really increasing the quality of the photo. His justification was something like, "Users were complaining about the output resolution not being 'full resolution' when zoomed in". My response was that that was ignorance on the part of the "photographer".
So to answer your question, not sure if ProShot can output "DNG" types of images, but the output was a JPG file (a pseudo 34MP image).
I will try using a tripod, possibly a motorized one designed for astronomy, and then force the OIS off (possible with Lumia Camera by setting the focus manually) - I need the OIS off because the lens gets slightly left behind by the rotation of the earth at that levels of magnification with the telescopic attachment causing a slight blur in long exposure images... or I could simply use shorter exposure times.:wink:
P.S.
Installed then uninstalled 1Shot before - don't remember why. I'll probably try it again and see how it compares against ProShot.
Update:
Just tried 1Shot now. First impressions: Aside from it's fast (under 1.5 seconds, which is similar to Camera360 Sight) start up time, there seems to be nothing special about it. Focusing time and quality are the same with Lumia Camera, Microsoft Camera, etc. White balance is the same. Detail recovery at high levels of magnification seems to be the same, though this needs further testing (just like my previous tests elsewhere). The zoom control, however, needs a lot of improvement - since when did moving my fingers away from each other mean zooming out-then-in?
