Dragon and Alexa – Looking at resolution – Part 3: The scaled-images

UHD

Here is the UHD scale for Alexa and RED Dragon (click on the images and zoom in to get a 1:1, low compression .jpg):

G001_C001_0206JZ

The 770 pixels untouched center-crop:

G001_C001_0206JZ

 

The center-crop with unsharp mask applied:

G001_C001_0206JZ

 

And finally a link to an uncompressed TIFF of the log center-crop.

 

1080

Fullrez 1080 scaled:

G001_C001_0206JZ

 

 

The 770 pixels log center-crop:

G001_C001_0206JZ

 

And the centercrop at 1080 scaled with unsharp mask applied:

G001_C001_0206JZ

And finally the unsharp mask TIFF

So far I have avoided commenting the results, but this final image really needs a bit of attention, before I move on to the final chapter of this writeup…

The difference in resolution at UHD, is just “as expected”. After all the Alexa image is upscaled and the Dragon is downscaled.
The difference at 1080 however is pretty interesting, as both the images are downsampled.
If you look at the upper left group of circles the difference is significant, even for 1080 delivery.

As to whether that is of any importance, I will discuss that in the final chapter of this comparison:

Resolution, does it matter?
