Week 2: Fersnel of my Heart

The fresenl is by far my favorite brushstroke. With that being said, most of the brushstroke lecture was review for me. I got to know them very in my plotting class, especially in regards to the idea of mixing them.

I’m surprised by how much was new to me (or I had forgotten) about the focal point of lights. It seemed vaguely family, and is something that I really should know. Hopefully I can get more tech experience before I graduate, especially since I was unable to help with Angels due to my illness.

One thing that was actually kind of cool about not remembering anything about the focal point was the trueness of the intuitiveness of light. My first instinct, when asked where the gobo would go for a clamp light, was to somehow attach the gobo in a way that would allow it to be several inches in front of the light fixture. Maybe it comes from having done several shows, working with lights in general, and/or focusing (especially with the cyc in the Nixon), but if I were in the position of needing a gobo for lights that don’t hold gobos, (and didn’t have this new found knowledge) I would keep putting the gobo in the space in front of the light until I got what I wanted (and then realize I need something bigger).

Knowing that the more curved a reflector is the closer the focal point is to the lamp is a good rule to know.
And the review about the 1 to 1 ratio for the 50 degree is something that will never get old.

I know in plotting we touched on the idea of coherency, but we didn’t give it a name. Again, it’s logical and intuitive. It’s like, if the photons were frosting, and the different degrees were baked goods, such as a 10 degree being a cupcake, and a 90 degree being a frosted cookie in the Guinness Book of World Records. (I’m still blown away there are lights that big).

My laptop doesn’t have the plug in for the virtual twin spin on GAM. Sad face.
