By definition a prism is a geometrical glass figure with...wait, stop; forget that. Just take a look at the cover of your Dark Side of the Moon album. That's a prism, and that's basically what it does.
I’m guessing the blue moon photo did its job and got your attention. It might surprise you to know that a key element in its creation was a weather app. We’ll get to the details of that shortly, but first, a few words about not-strictly-photographic accessories.
There’ll always be an opportunity to make a photograph. What makes that photo more than simply a record of a place, what will turn it into a creative image, is how you deal with the opportunity—and sometimes how far you stretch it.

It's not what most photographers would consider essential glass, but in mid-2017, when I heard it was available, I knew the 8-15mm f/3.5-4.5 fisheye Nikkor was a lens I'd like a lot. What I didn't realize was how much "a lot" was going to be. It turned out that I liked to have it with me whenever I was photographing.
