I saw a bunch of these guys on my way down to Scripps Pier last night. The fog was rolling in, and I guess they like the moisture a lot. I couldn’t resist the urge to pull out the Promaster close-up filters (I used both the +1 and +2 filters) and the flash. What I wouldn’t give for an actual macro lens! But slapping those filters on a 50mm lens works pretty well, although it can be a bit frustrating figuring out how far/close you have to be to the subject to actually focus on it (basically the filters just let you focus at a shorter distance than the lens usually allows).
