Random Thoughts on Photography [7] ~ SuperResolution, a better solution

I spent a bit of time looking at single image and multiple image stacking UpScaling.  As a friend suggested several years ago, there's a simpler way.

If one has the time, image stitching for true SuperResolution is a very fine solution.  Having a tripod helps.

Consider the following.  I used a Sony A6300, a Sigma 19mm f/2.8 EX DN E, a tripod, and a small "L" bracket that I made before moving to place where access to materials and tools is very difficult to non-existent.

There's a trick to using the "L" bracket and it's simply this: I have to make sure I put the pivot point directly under the lens' nodal point.  In practical terms, make sure the tripod head mount screw sits under/aligns with the lens aperture location.  When done in this way and by swiveling the tripod head to capture overlapping sections of the scene, image stitching is a breeze and all image elements quickly align.

The dimensions on the long side is well over 9,000 pixels.  100% crops are along the top.  The full scene is under the crops.  There's no lack of definition/resolution.  

My friend was, of course, correct.  There is a simple/inexpensive way of achieving SuperResolution and this is it.
