Thanks Lars for the article and the examples.
Since my Lumia 1020 offers RAW ... I'm using it. In most cases I use it, because I don't have the ability, like with iPhone apps, to set a a bright and a dark point for exposures. So I often underexpose my images to have details and no clipping in the brightest areas.
This ends up having some noise in the dark parts of an image when I raise the exposure in the dark parts in ACR.The Nokia 1020 often tends to have vertical banding in the noise when I do that, but TOPAZ DeNoise is perfect for that, because it has a specialized setting for the vertical banding.
The JPGs out of the Nokia are very good, but since it is possible I prefer using the DNG files.
I'm using the Nokia 808 and the Lumia 1020. In most cases it's not only the sharpness that is better than pictures taken with the iPhone, I have the ability to crop!
Alex Efimoff: I reckon shots taken with Pureview 808 have better quality.
As far as I have seen images from the 1020 I agree. I wish I would have the onscreen adjustments for the camera as with the 1020, but I'm sure the image quality of the 808 is better.
