Cameron Day 3 – the Mystics of Optical Density

It’s… Get ready for it, HUMPDAY!!!!!

Anyways, hi friends!

Cameron again. I hope everyone is enjoying their week so far. Mine has been especially fabulous, and we started a new activity in preparation for the main project. Yesterday, I cleaned filters and put them in their proper placement. Today I tested the optical density of each, which is where we place them into a machine and run them through the color spectrum, recording how much light gets through. Hers a picture of the machine:


Jason McNeill (in the picture above) was my guide during this activity, and it was quite interesting utilizing the software. Despite several technical difficulties, I ended up processing all 50 plates in time for Jason to check their weights using a very, very picky machine. It took 15 minutes for just one filter at one point!

After helping out Jason, Mrs. Michelle took me to meet Andrew Dart, where we discussed some of the finer points of his machine. This machine, as it so happened to be, was the one we used for ECMs, and is picture below along with Andrew.


Andrew built both this and the extremely complicated machine hidden behind the one we used. It’s pretty awesome! He also works on the fireman project I discussed in my first post. Pretty cool, right? Not to mention he looks kind of like Sherlock from Masterpiece Mysteries…

Anyway, that’s pretty much everything for today.

Happy Humpday everyone!

Cameron L.
