The Exposure 360 Triangle: Aperture, ISO, and Shutter Speed

The Exposure Triangle is a 360 degree photographer’s basic tool, and it will help you find the best exposure for your specific photos. It is controlled by the aperture, the ISO, and the shutter speed of your camera. Each of these settings is responsible for taking the best picture possible. Wren you adjust the light (aperture and ISO) you will also have to adjust the shutter speed in order to accommodate for the change in light.

By accommodating for these three settings, you will learn how to control the relationship between light and shutter speed in your 360 camera and take amazing photographs. Choose the Best 360  camera 2016 in easy with our blog.

The first step is the aperture. As discussed in the introduction, aperture controls how much light gets into your lens.
The larger you set the number, the smaller it becomes, giving you more depth of field in order to take large, sweeping photographs where everything is in focus.

The smaller you set the number, the smaller your depth of field. This means that only the main subject of your photograph will be in focus while the surrounding parts of the image will be blurry. You want a smaller depth of field if you’re taking pictures of specific, smaller things, like petals, insects, or jewelry. In order to set the aperture for these small focuses, your camera must be in manual mode. Note the dial above your program dial – it’s black and grooved.

How do you feel with your first 360 camera?

Below it are two buttons. The one on the right is the exposure compensation button. Hold this button down and turn the dial left or right to adjust your aperture. For tiny objects, an fi.4 of f2.8 setting is perfect. Once you’ve adjusted for the depth of field, you may have to modify your ISO. On your Canon 360 camera, the ISO settings available to you are 100, 200, 400, 800, and 1600.

ISO100 is the default setting, and if you’re shooting at an fi.4 in a well-lit area, it will be fine. But if you’ve closed the aperture with a higher setting, such as f22, and the area is dark, you may want to bump your ISO up to 400 or 800 in order to capture the right image.

Changing your ISO is as easy as pushing a button. When looking at the LCD screen of your camera, note the “SET” button to the right. It is surrounded in a circle by 4 other buttons.

Pushing the top of these four will change your ISO speed. Remember, if you’re moving your ISO up, it is not necessary to use the flash. Third and finally, the shutter speed must be adjusted in order for the new ISO and aperture settings to actually work.Because you’re changing the amount of light going through the lens, you’ll need the lens to open and close at the right speed in order to capture the right amount of light in your photo and avoid overexposure.

With your small aperture for tiny objects and an ISOioo setting, the default speed should capture the image you want. You could speed it up if you’re focusing on tiny moving objects, like bugs, because the faster the shutter speed the less blurry the picture will be, but that isn’t always necessary. On the other hand, if you’ve increased the aperture and your ISO speed, then you’ll need to speed up the shutter as well.

To change your shutter speed on your Canon 360 camerayou will use the same dial you used to adjust the aperture, just don’t hold down the exposure compensation button. Take a look at your LCD screen as you move the dial back and forth to make sure you’re moving it to the desired speed. Remember, shutter speed is in the top left of your screen and reads 1/4000 when at default setting.

You want your shutter speed to correlate with your aperture and ISO, so if you’ve doubled the latter two, then double your shutter speed. Now, you may want to play around with it a bit, so adjust the speed faster and slower and take a few pictures to see how it works out until you find the exact speed that you want. With these three settings in your Exposure Triangle, you will be allowing the right amount of light into your image.

And now that you know how to adjust them for the perfect picture, you can start playing around with overexposure in order to create some truly artistic pieces or to simply accommodate for unfortunate natural light settings in your photography space. For example, if you’re taking portraits and the sun or light source is behind your subjects, a little overexposure can help you light up faces without losing too much from the background. Manually adjust your exposure by pressing the same exposure compensation button you used to adjust the aperture, but this time don’t turn the dial.

Just press it until you reach the desired exposure you want on the -2 to +2 scale. When pressing the exposure compensation button, you are telling the camera to ignore its default metering settings. Metering is one of the more difficult aspects of photography and can be a little frustrating for those just beginning to use their Canon 360 camera. But now that you understand the exposure triangle and how to adjust it, you can move on to the next chapter about metering and learn how to accommodate for brightness and color saturation in your photos.
