Living in Houston, it’s usually very hot and humid here. One of the downfalls is coming from inside a building or the car with AC on cold and then proceeding to go outside to shoot when it's hot outside. Whether it's moving from a cold to warm environment or vice versa, the drastic change in the temperature could cause your camera lenses to fog up. What can you do?
Unfortunately, there aren't many options to help remedy the problem. You could grab a lens cloth to wipe the front of the lens and if that doesn’t help then you just have to wait. So what can you do? Pre-planning for your shoot can help reduce the chances of your gear from fogging up as David Bergman explains in the video from Adorama.
If you know you are going on location to shoot and it’s going to be a drastic change in climate, leave the camera in the trunk of your car or leave it out prior to shooting to give it time to adjust. I wouldn’t suggest leaving it on the ledge of a balcony as shown in the video, as that could lead to other issues. Another idea is to leave your lens in a plastic ziplock bag and let it sit for a couple of minutes in the sun. The condensation should form on the bag and not the lens. If you have any of those silica gel packets you could throw those in as well to help. Hopefully, these tips help you in preventing your gear from fogging up for the potential shoot.
