Seeing Clearly or Blurred and Knowing When to Do It

When taking pictures, there are a variety of options that you have at your disposal. I am going to address just a few of these options in this post. Including aperture, shutter speed, and controlling ISO settings.

Aperture size

The size that your aperture, the opening of the front of the camera, is decides how much light is allowed into the camera. By increasing and decreasing that size, you can control how blurred or sharp your image will come out. These aperture sizes are measured in f-stops. The wider the aperture you want, the lower the f-stop number. Likewise, smaller apertures are achieved with larger f-stop numbers. You will use different aperture sizes depending on what you want your image to focus on.

Wide Aperture

Having a wide aperture allows in more light. You want to use smaller f-stops like f/2.8 to achieve this. This makes it so the background is more blurred, and it creates a greater depth of field. This helps when you want to emphasize a subject of a photo, rather than the entire shot.

Example of a wide aperture

Narrow Aperture

Having a narrow aperture restricts how much light is allowed into the camera. This is best used when you want the picture to be sharp and you want the background to be just as visible as the foreground. An example is to capture scenery shots, especially when you are trying to capture something in the distance, but you want the rest of the landscape as well. You want to use larger f-stops like f/16 for these shots.

Shutter Speed

Fast Shutter Speed

As stated, this is fast. The shutter opens and closes quickly to snap the picture. This is advantageous when you want to catch something that is moving quickly, such as a sports game, and you want a snapshot of the game. Leaving the shutter open too long, in this case, causes blurred images.

Example of a fast shutter speed

Slow Shutter Speed

This is when the shutter stays open longer and thus lets in more light. This allows for capturing some motion. For example, when trying to take a picture of the water in the image, if you used a fast shutter speed, then the image would catch one moment, but it wouldn’t look as natural. By using a slower shutter speed, the camera was able to catch more of the motion and incorporate it into the image.

ISO Settings

By manipulating the ISO setting on your camera, you can combat different light settings. In extremely dark situations, you’ll want to use a light source of some kind, but if the light is a little bright or dark, you can use the ISO to offset the lighting. Using lower ISO, like 100, is ideal for brighter sets, but as it gets darker, you can increase the ISO to still take good pictures.

  1. Seth,

    I like how you broke up the blog by giving insight on what Aperture and shutter speed is as a whole then you broke it into the smaller sections. I also like how all your images are the same height and width it gives the is post a very cohesive look. Also, the way that you explained what the sections do when you use the settings was simplified to a point that someone with no camera experience would be able to understand. Great work!

  2. Great post Seth! You explained each section very clearly so that even someone without any photography experience could understand. I loved the specific examples you listed for each one, like saying a fast shutter speed would be good to use to photograph sports. I also thought you did a great job choosing your photos and your title is very creative!
