I've seen a ton of posts about "the top x things I use in my photography"; I'm sure I'll get around to one of those sometime. For now, I have very little equipment - one camera and one lens and the remains of what used to be a tripod before it became the victim of an unfortunate accident whilst shooting a meteor shower - but I do have one item that has quickly become one of my favorites.
I have no idea how this thing showed up in my Amazon recommended items list, but it did. I don't typically (read: ever) search things that could be even remotely related to "HEALING CRYSTAL BALL TO SEE YOUR FUTURE" (in all caps), but it found its way there anyway. It's definitely the best fifteen dollars I've spent on a non-cooking related photo prop.
It took me a while to figure out just how I wanted to use this. I didn't really like what it did with portrait work, though it did create an interesting effect in a couples shot I took. I noticed that most people who use these in photos use them to invert various architectural structures - I saw some really nice shots of the Eiffel Tower through one of these, among other things - but since neither Florida nor Kansas are known for magnificent manmade structures, I was at quite a loss as to what I should do with this.
And then I took it to the beach.
I've discovered that the only challenge when shooting with this thing is that you have to be at the exact same level as it is. In the process of attempting to do this, my camera and got rather sandy and almost went for a swim more than once. The result was some of my favorite photos I've ever taken.
I also got two great shots of the water which are some of my favorites as well.
