At Golden Hour: the Dom Tower of Utrecht captured by four smartphone cameras
I was in Utrecht the day after I visited Amsterdam (where I made this comparison) and was very happy to suddenly see this scene, with the dark foreground and the incredibly bright shining tower.
This is the (resized, but otherwise unaltered) result of the 38MP shot with the Nokia 808 PureView:
Now I made more or less the exact same shot with - as you are used to by now - the Nokia Lumia 920, Samsung Galaxy S4 and HTC One. You will find all originals on Flickr.
What I did to compare them this time is crop them to 1520 x 855 pixels - 1520 wide because that's the maximum width of the HTC One, and 855 high since that gives me a 16:9 format (so it's easy to change to 640 x 360 to share them here). You'll find the 1520 x 855 crops on Flickr as well.
I'll show you the results in 2 x 4 shots - first those of the foreground, focussing on the flags, centuring around the one depicting the tower itself.
You'll see you are closing in with first the 4MP result of the HTC One, next the 8MP result of the Nokia Lumia 920, then the 13MP result of the Samsung Galaxy S4 and last the 38MP result of the Nokia 808 PureView.
Second round, focusing on the clock of the tower. Again, first the 4MP result of the HTC One, next the 8MP result of the Nokia Lumia 920, then the 13MP result of the Samsung Galaxy S4 and last the 38MP result of the Nokia 808 PureView.
Again, you can see all originals shots and crops on Flickr).
There has always has been a lot of discussion about "Megapixels" - the fact that they "wouldn't really matter". Especially HTC has been boasting their new "UltraPixel" technique, and we now know what it looks like.
This method is another way of focussing on the detail and proving how the amount of Megapixels really does make a difference (provided you have everything else covered right as well of course: optics, algorithms, etc.)
Don't hesitate to tell me what you think of the differences :-)
