A bigger opening, or aperture, lets more light pass through than a smaller opening, much in the same way a bigger hole in the bottom of a bucket lets more water leak out than a smaller hole.
The amount of light it lets in is largely dependent on the size of the physical lens opening.
The lens on your camera is designed to gather incoming light and focus it so you can take a picture. If you find that you consistently get blurry pictures of your subjects, try increasing your shutter speed and you just may just be surprised with the outcome.
#Focused pictures software
Most photographers would take a slightly grainy (noisy) photo that can often be fixed with software like Lightroom or Photoshop over a blurry photo that can usually not be fixed.
#Focused pictures iso
You can also utilize higher ISO settings like 1600 or 3200, which look just fine from most modern cameras if you need a fast shutter and there isn’t much light. So shooting in Program or Shutter Priority is a good way to control the shutter speed to make it as fast as you want. If you shoot in Auto your camera might not know you want to use a fast shutter speed. The solution is to use a faster shutter speed, which might sound fairly obvious but it doesn’t always work unless you have your camera configured properly. This jittery squirrel was moving all over the place, so I shot with a speed of 1/180 second to get a sharp picture. It gets even worse when your subject is moving, in which case you need a much faster shutter speed! This is why many mobile phone pictures end up looking blurry, in order to let in enough light to get a photo they often use slower shutter speeds. This might sound fast but it’s actually not, especially if you are shooting in low light conditions or with a small aperture on your lens.
#Focused pictures series
Note: Due to the cropped sensor on cameras like the Canon Rebel series or lower-end Nikons the formula becomes 1/(1.5x focal length), so you would need a minimum shutter speed of 1/75 second. So if you are shooting with a 50mm lens you need a shutter speed of 1/50th of a second. There’s an old bit of conventional wisdom that says the minimum shutter speed needed to get a sharp image of a still subject is 1/focal length. Depending on what you are shooting the result can sometimes be a blurry mess, which is often the result of a shutter speed that is simply too slow. The world around you is constantly in motion, and having a camera means you are equipped to freeze that motion into a single frame. Fortunately, there are a few relatively simple things you can do to make sure your pictures are indeed as sharp as possible.
It’s an unfortunate reality of the way cameras work with incoming light, and until we are all shooting with Lytro-style light field cameras we are all going to have the occasional out-of-focus picture or two. While new cameras offer all sorts of features like 3D focus tracking and real-time face detection to help make sure to get the ultimate tack sharp photos, the fact remains that out-of-focus images are still an issue for just about everyone with a camera. It’s a problem that has plagued photographers for years. You get home from an afternoon with your kids in the park, at the ball game, or even a formal photo session only to load your pictures on the computer and realize that many of them are fuzzy, blurry, or just plain out of focus.
