There are plenty of opportunities out there to take pictures underwater, but waterproof digital cameras are going to be some of the best devices for doing that. Moreover, it's important to think about the camera and how it has evolved. Digital cameras in general have provided pictures with much better resolutions, and you can also store them electronically. They have continued to fit the way the world is moving forward as people are sharing digital photos on social media and all over the Internet.
Do you remember when people were processing photos onto CD's? It was during that transition period when people using regular cameras still wanted digital photos as well. I still have tons of CD's with photos on them. I have a bunch of old traditional photos, too. There is something to be said about photographs in print, but you can always print out your digital photos. People just don't always seem to do that these days.
Digital cameras provide so many advantages, but one of the flaws they have is that many of them aren't waterproof. They are an electronic device. Think about when you're at the pool on vacation, and you go to take a picture. There are all kinds of places where water can easily find your camera. You don't have to drop it into the pool. What about sweat? Without waterproof digital cameras, you have to be extremely cautious, which means you might not be able to get the picture taking opportunities that you want.
You certainly can't go underwater with a digital camera that isn't waterproof. It seems like a digital camera that is waterproof would definitely be the best selection. However, you want to be sure you're not sacrificing picture quality. You still want a high quality camera, and you want to be able to get the types of pictures you want to take.
Imagine taking a waterproof digital camera on vacation and taking pictures while snorkeling. That would be really cool. Imagine not having to worry about a little bit of water getting on your camera while you're out and about. There are a lot of things to think about and keep up with when you're on the go, so the last thing you want to have to worry about is your camera getting wet. If it gets wet, it gets wet. It's okay! You have a camera that is waterproof.
