Which digital cameras are best for shooting in extreme conditions?
Digital cameras are all the rage these days, and with the proliferation of smartphones, we’re all used to snapping a few pictures with our smartphone.
But there’s a catch: You’re usually doing it in extreme weather conditions.
Now a new study suggests that extreme weather photography can be even more challenging in extreme terrain, with some cameras even having trouble with the conditions.
“If you’re using a digital camera with a lens that is designed for high ISO, or you’re shooting with a digital sensor that has a relatively high shutter speed, the shutter speed is very slow to reach the maximum aperture of the sensor,” says photographer Bobby Digital.
“So the lens is getting in the way of getting a high ISO image.”
This can cause the sensor to lose the ability to capture the details of the image, which means the image won’t be as sharp.
“A lot of the time, when you’re photographing in extreme environments, you’re not getting the maximum image quality because the lens doesn’t get in the foreground and you can’t get a great image,” says Digital.
The researchers also found that the lenses of some digital cameras also don’t provide a very good contrast ratio.
This means that when the subject is in the frame, the light coming in from the subject doesn’t make much of an impact.
“In extreme environments where the ambient temperature is in excess of 80°F or more, that means that the contrast ratio will be low,” says Bobby Digital, adding that this can result in a very blurry image.
“You’re actually creating a lot of noise, especially in the background.
And that noise is not a good thing to have in your image.”
Another problem with the digital cameras is that they’re not always equipped with a high enough aperture to capture details.
“For example, if you’re taking a photograph of a dog, you could be able to capture more detail in that dog because you could see the dog’s legs, and there are no details on those legs,” says Charlie, another photographer.
Charlie is also concerned about the lenses in some of the digital camera models.
“Some of the lenses are a little too small, which is really limiting your ability to get a high quality image,” he says.
“Another problem that we see with a lot the digital models is that you’re looking at a sensor that’s a little bit small.
And then there’s the other issue of the focus distance, which I guess is another limitation.
You’re not focusing at the correct distance, so the background doesn’t come into focus,” says one of the photographers, Charlie.
“And that’s really a big limitation.”
Digital cameras also aren’t always waterproof, which can result into a blurry image in extreme cold weather.
“When you’re capturing a photo, it’s actually a pretty hot and humid day,” Charlie says.
In extreme conditions, you might not be able make the camera waterproof, and you could get a blurry photograph in a cold weather environment.
“It’s just something that people should be aware of,” says digital camera owner and photographer Bobby, adding: “There are other cameras that can take a good photo in extreme temperature and cold weather, and they’re better for that than digital cameras.”
The study is published in the journal Optics Express.
