So I realized yesterday that seeing an image taken in the middle of the winter may not be the most appropriate thing to post at the beginning of the summer, so I decided to send you all off to your weekend with a nice beach shot. That’s actually a totally garbage anecdote, I just needed a way to start off today’s post, other than just saying “Hello, everyone!” Hope you enjoyed it.
Yes, this is another shot from my Jamaican vacation a little while ago. I’ve still got a ton of pics left from that trip, but I’ve basically covered all the major themes. (I’ve got a beach shot, a beach shot with a boat, a sunset shot, a sunset shot with a boat.. you get the idea.) But, as long as I space them out a bit, I figure it’s ok.
Now, for the meaty part of the post. I believe I’ve mentioned at least once or twice before how useful a polarizing filter can be. (In fact, I think I said something along the lines of “If you go to the beach without one I’ll hunt you down and say derogatory things to you until your self-esteem is significantly worse than it was before.”) So it turns out that, while I was in Jamaica, I was playing around a bit with the video feature on my current SLR (Canon T1i), and I took a couple movies with the polarizer on there, so you can see what it actually does for you. It’s one thing to talk about it, but it’s another thing entirely to actually SEE it. In case you’ve never seen or used one before, a circular polarizer is a filter that you screw on to the front of your lens like any other filter. However, unlike most filters, it’s actually comprised of two pieces, such that the actual glass part of the filter can freely rotate on your lens, because the polarizer does different things depending on the angle of the light. In practice, this changes the effect of the filter from being almost negligible (well, it basically changes it just into a neutral density filter, which has the effect of just dimming the light, like sunglasses, without affecting the color at all) to being full-on polarized. Thus, when using one, you rotate the filter to get the effect you want, then you take the picture. So, in the video below, that’s what I was doing, just rotating the filter while recording the video. This doesn’t really require explanation if you actually watch the video, but watch what it does to the water, and you’ll understand why you should never go to the Caribbean without one.
Right, on that note.. Have a great weekend!
