Lumia 1020 RAW quick comparison

Having received Lumia ‘Black’ a few weeks ago on my Lumia 1020, and then yesterday receiving an update that brought RAW DNG capabilities to the phone as well, I thought I’d upload a couple of photos for people to look at to see if they can see any difference between the shots in terms of detail or colour.


I’m not a photographer so using DNG mode is something that I’m unfamiliar with, but I am interested if it improves the overall image quality of my shots.


Both of these photos were ‘Shared’ via Bluetooth to my MacBook, and they are both around the 1.6MB mark, but the first one was taken with Settings set to “5MP + 38MP” (as standard before Lumia Black) and the second one was taken with the newer “5MP + 38MP DNG”.

Attaching my phone to the Mac via USB and opening up the Mac Transfer app, it revealed the DNG shot as being 43.7MP (gulp!) and I don’t have fancy photo editing software like Aperture, so I don’t even know what the quality of the hi-res RAW pic is like.


Anyway, chances are that both of these pics are similar 5MP shots that the 1020 spits out for ‘sharing’, although they both have different file names, and sizes (see caption of each pic for that info).

Here they are: (click on them for full resolution)



WP_20140111_11_15_43_Pro.jpg (not DNG mode) Size 1.5MB
WP_20140111_11_15_43_Pro.jpg (not DNG mode) Size 1.5MB


WP_20140111_11_16_02_Raw.jpg (using 34MP DNG mode) Size: 1.6MB
WP_20140111_11_16_02_Raw.jpg (using 38MP DNG mode) Size: 1.6MB

They look identical to me, despite the different modes and the 0.1MB difference in file size. But that’s just me. And seeing as I wouldn’t know the first thing about editing RAW photos in Aperture or PhotoShop, I think I’ll just stick to what I know. And even that isn’t much! ;^)

  1. After reading your post, instead of just on Twitter, I must say that, if you transfer via Bluetooth the pic to your computer will compress the shot, you MUST use USB instead. Using symbian doesn’t mind this, but WP compress while transfering via BT, or that’s what told me an employee of Nokia
    And, upload the full DNG shot to compare the picture, because uploading the jpg doesn’t give anything different, I mean:
    – DNG is the full info shot, without compressing, a process that removes info (pixels data)
    – JPG compressed picture
    Making a JPG from the DNG is what does the mobile when capturing a picture with 5MP mode, or 5+34MP mode
    Cheers! =)

    • Thanks mate, I sort of knew some compression was going on as the file sizes became so small, but I was still interested to see if there was a difference on the shots, even if they were being compressed. I’m sure if I got the RAW file open somehow the detail would be amazing (it is a HUGE file afterall!) :^)
