It can get pretty hot in the midwest and while I am not a huge fan of 100+ temps, it comes with the job when you're shooting outdoor summer weddings. It's important to know that your gear is affected by the hot weather and what you can do to extend the life of your gear while in warmer temps. Below are the things that I do during the hot summer months to take care of my gear and make sure it's ready to go!
Let your camera warm up
Have you ever arrived at a shoot and pulled out your camera only to realize that your camera was fogging up? It takes about 10 minutes for your gear to adjust to the warmer temperatures, so make sure you plan ahead during these warm summer months!
Use a plastic bag
If you bring your camera from a cool place to a hot place, it's going to condensate! All of that moisture build up inside your camera isn't good for it. If you want to be extra cautious (and you always want to be cautious with film), put your gear in a ziploc bag. All of the moisture will build up on the outside of the bag instead of on the outside of your gear!
Keep your camera in the trunk of your car
It's better for your gear to slowly transition into different temperatures so I like to keep my gear in the trunk of my car when I'm traveling to a different location (i.e. ceremony, reception). This helps the film to remain a consistent temperature.
Keep your gear in the shade when possible
If you're shooting film, you know that you need to store the film in a cool, dry place. If you're shooting in 100 degree weather, you can take care of your film by keeping it in a little bag that sits inside your main bag. If you prefer to shoot with an apron, try to reload and unload your film so that all of the film isn't in the extreme elements all day long.
It's rare that a digital camera will shut down during the heat, but it's possible if the camera gets overheated. If you're not using the gear, leave it in the shade or have your assistant stand in the shade with the gear. Try to avoid setting it down in the sun at all costs.
