To get that nice 'twinkle' effect on bright lights, such as Christmas lights, street lamps or the sun shining through a branch, you can either buy a special filter or just increase your aperture!
(or, we can use my alternative title: f-numbers really do make sense, despite what the person in this photography video is telling me.)
As long as I can remember, I've been a combination of artist and nerd. Ignoring, for a moment, my teenage angst years where I did the exact opposite of what my parents wanted for me, I have always loved learning, researching, creating and learning even more about myself and the world around me. (My good friend Meghan called me the 'Book of Useless Information,' which I take as a huge compliment!)
This is why photography is the perfect hobby and skill for me. It combines creativity within specific constraints (which I love), and there is always something new to learn, to experiment with and to explore.
