We all know that digital images are made up of red, green and blue “pixels”. Often, to capture this, sensors are in some kind of side-by-side pixel array, like with Bayer and X-Trans or layered, like Foveon. But that’s not the only way to create a full colour image. Many video cameras do it with the use of a prism splitter and three separate sensors capturing red, green and blue signals which are then merged together....
The one certainty in photography is that the closer we get to our subjects, the shallower our depth of field becomes. If we’re shooting with a macro lens, we have the option to stop our lens all the way down to increase the depth of field. Sometimes this can be enough to give us what we need. And sometimes it can’t.

Unfortunately none of these flashes have a public API, and some even go to the trouble of encrypting their bluetooth messages. What the heck?! I don’t have much experience with Arduino development, or electronics in general, but the market forced me into it!...
