Summer is here and for many of us that means going to a beach - whether it’s just a drive away or a cross-country flight. But that doesn’t mean you have to give up on photography! There are great opportunities whether you want to do landscape photography, wildlife photography, or portrait photography. Let’s start by talking about equipment. The equipment you bring to the beach depends on your purpose for being at the beach that day or that session. If you’re going specifically to take photos, then you’re probably OK bringing your dSLR and, optionally, flash. If you’re going to the beach to enjoy it and also want to take photos, you’re best off getting an underwater housing for your camera or getting a weatherproofed camera. Sand and sea salt (which is in the air at the beach) are both VERY bad for cameras and could wreck your expensive camera. If you will be having fun you don’t want to take the chance that someone who’s with you or a stranger kicks sand onto your camera accidentally. Also, sometimes waves can come up farther than you realized at first. An underwater housing or weatherproof camera is protected from the elements. It also has the bonus of allowing you to carry it with you into the water (should you happen to be at a beach where you can get into the water) and lessens the chances of your camera being stolen.
