Testing out something called a 'focal reducer' - basically the opposite of a teleconverter - and see how well it worked with the images. I like the colors, and the way it captured almost a 3D look on the lamppost.

(A teleconverter is a lens attachment that enlarges an image by spreading it out - but in the process, makes it dimmer and fuzzier. Think of it like moving a projector further away from the screen - the image gets bigger, but because it's the same amount of light being spread across a wider area, it looks darker and not as sharp. A focal reducer does the opposite thing - takes the same amount of light and concentrates it in a smaller area, making the image brighter and sharper. This can work because you're taking lenses originally designed to cover a frame of 35mm film and using them on a camera with a digital sensor smaller than a 35mm frame.)
