My first attempt at snowflake macro, and while not the best I think it was a cool learning experience. Snowflakes are so beautiful. I love how nature is chock-full of fantastic fractals. Next is to attempt some focus bracketed shots. All images were quickly processed with Darktable.
They increase the distance between the sensor and the lens, which allows you to get closer to the subject than the lens typically allows. This effectively increases the magnification.
