  History If you are reading this you probably already know about the iconic look of Kodak Aerochrome film. The iconic false color Infrared film used for Arial photography produced vibrant red/purple images of vegetation. It's origins where for surveillance as artificial structures would stick out. Eventually it made its way into the hands of photographers. A number of album covers allegedly used the film for its surreal colors. The first artist that made me fascinated by the film was Richard Mosse work in the Democratic Republic of Congo.  But if you are like me, between the difficulty and expense of purchasing and using it, I never was able to shoot the real thing. The Basics The best place to start when trying to replicate something ourselves is to take a look at the orginal. Luckily we can view the datasheet  to understand what is happening. On the first page Figure 1. Provides the best information for how the false colors work showing how the different layers are exp...

Panoramic Lens Substitution

  Background Since I first started taking photos, I was interested in taking panoramas. I was both inexperienced and the tools accessible to normal photographers at that time where very limited. My early attempts were made using tripods, attempting to mount the camera close to the center of the nodal point of the lens, and then very carefully manually stitching photos together.  Lacking the correct and expensive tools, the process was tedious, and error prone One of my first attempts at a Panorama Eventually I stopped attempting panoramic images as the results where never very successful. (I did try other ideas circa 2007)  Revisited That eventually changed when a technique  Ryan Brenizer  became popular somewhere around 2012-2014. ( I can't recall when I first encountered it) This method was taking a long fast lens and taking photos to cover the entire area of what a larger format would cover.  The result is both an impossibly thin depth of field combined ...
