Use a Soft Brush
A small, soft brush is the best tool for removing sand from your camera lens. Hold the camera so the lens is facing the ground. Brush the lens from the middle toward the edges. Then brush gently in a circular motion around the edges of the lens to dislodge any particles of sand. Using a gentle brushing motion is the key to prevent scratches on the lens.
A small, soft brush also works well to remove particles of sand from the seams of the camera body, around buttons, and around the LCD.
Other Options
If you don’t have a brush available, a microfiber cloth works well, too. A third option is gently blowing on the areas where you see the sand.
The Best Approach: Prevention
If you’re reading this, it’s probably too late to prevent sand from getting into your camera—but these strategies can help so you don’t ever have the problem again.
Bring a Bag
If you’re going to the beach, always take a camera bag or backpack with you so you can give your camera maximum protection until you’re ready to use it. Consider investing in a waterproof bag, which will protect the camera from spray and inadvertent splashes. Remove the camera from the bag only when you’re going to shoot a photo.
Plastic Is Your Friend
In lieu of a waterproof bag, use a plastic bag that can be sealed, such as a Ziploc, to store your camera. Sealing the bag whenever you aren’t using the camera can go a long way toward protecting your equipment from both sand and dampness. Better still: Place the plastic bag inside a camera bag for double the protection.
Such physical means of protection are even more important for old or cheaply made cameras with body seams and button seals that are not as tight as they should be.
Keep Liquid Away
Avoid keeping other sources of liquid—for example, sunscreen, water bottles, cleaning solutions—in the same bag as the camera. If you must carry everything in one bag, seal each item in its own plastic bag.
Use a Tripod
One of the best ways to make sure that your camera doesn’t end up with sand on or in it is to use a tripod throughout your beach photography session. Just make sure the tripod is securely balanced so your camera doesn’t fall into the sand.
