Have you ever looked inside a macro tube to examine the optics there? haha. No optics, it is just a big tube filled with air.* This is why it is an extremely easy device to replicate. Maker Vinnie Hirt used the macro tube quality of nothingness to build his own set of an uber extension tube for a mere $5 give or take.
Welcome to my tutorial on how to make a 3 point light setup kit that allows you to vary the point LEDs independently. I wrote this for fun and i hope it inspires you! Warning: ManualMode.ca and I are not responsible for ANY damage caused to you, others or your household while following this tutorial.
I decided to make this kit because i shoot macro a lot and I’ve been disappointed by the macro mini studios i bought mostly because i could not control the light intensity for each bulb and even if I hacked it into a dimmable solution, fluorescent lights do not dimm, so i had to buy special white light tungsten bulb. I was also limited by size of the bulb and the heat it generated. All i wanted is to have positional whitelights that can vary their brightness and small enough so i can use it for macro.
Before I dive in, look at the lead image to see some quick tests I made with the completed setup
For those who don’t know, cartography is the making of maps. The word comes from the french terms carte and -graphie, which literally mean map and writing. Daniel Boschung is a face cartographer, and he does exactly what that title suggests: he makes geographic landscapes out of portraits of the human face.
The maximum resolution of a perfect human eye is around 450 pixels per inch (PPI). That means if you’ve got a smartphone, like the iPhone 5S, you probably wouldn’t notice the separate tiny pixels that make up the screen because of its display of 326 PPI. The screen looks almost as sharp as real life. Keeping that in mind, if you were to take a 90 x 90 inch portrait of one of the faces photographed by Daniel Boschung in this project, the final resolution of the picture would amount to somewhere at 111,000 PPI.
