What Is Exposure?
Exposure is the amount of light that hits your camera sensor. It’s measured in seconds, and it determines how bright or dark your photo will be. If you want to take a well-exposed photo, you need to make sure that there is just the right amount of light hitting your sensor. Too much light will result in a photo that is too bright, while too little light will make your photo appear dark.
What Determines Exposure Of A Photo?
The exposure triangle is a helpful way to understand exposure in photography. It’s made up of three different elements: aperture, shutter speed, and ISO. Aperture is the size of the opening in your lens. Shutter speed is how long your camera’s shutter stays open. ISO is the sensitivity of your camera sensor.
All three of these elements work together to determine exposure. If one of them is changed, the other two will also be affected. For example, if you want to make your photo brighter, you can either open up your aperture or slow down your shutter speed. Or, if you want to make your photo darker, you can close your aperture or speed up your shutter speed. It’s up to you to experiment and find the perfect exposure for each photo.
Aperture
Aperture is the size of the opening in your lens. It’s measured in f-stops, and the lower the number, the bigger the opening. A large aperture (low f-stop number) will let in more light, which is good for low-light situations. A small aperture (high f-stop number) will let in less light, which is good for bright situations.
You can control aperture by using your camera’s exposure compensation feature. This will let you make your photo brighter or darker without changing the shutter speed or ISO.
Shutter Speed
Shutter speed is how long your camera’s shutter stays open. It’s measured in seconds, and the longer the shutter is open, the more light will hit your sensor. A slow shutter speed is good for low-light situations, while a fast shutter speed is good for bright situations.
You can control shutter speed by using your camera’s exposure compensation feature. This will let you make your photo brighter or darker without changing the aperture or ISO.
ISO
ISO is the sensitivity of your camera sensor. It’s measured in numbers, and the higher the number, the more sensitive your sensor will be to light. A high ISO is good for low-light situations, while a low ISO is good for bright situations.
You can control ISO by using your camera’s exposure compensation feature. This will let you make your photo brighter or darker without changing the aperture or shutter speed.
Different Types Of Exposure
There are different types of exposure that can present itself in photos, which we’ll cover below:
Overexposure
Overexposure happens when there is too much light hitting your sensor. This can result in a photo that is too bright or has washed-out colors. Overexposure can also cause “blown out” highlights, which are areas of the photo that are so bright they appear white.
Underexposure happens when there is not enough light hitting your sensor. This can result in a photo that is too dark or has muted colors. Underexposure can also cause “clipped” shadows, which are areas of the photo that are so dark they appear black.
You can avoid underexposure by using your camera’s exposure compensation feature to make your photo brighter. You can also try using a larger aperture (lower f-stop number) or slower shutter speed.
Long Exposure
Long exposure is when you use a slow shutter speed to let more light hit your sensor. This can be used to create some interesting effects, like light trails or “ghosting.”
Double exposure is when you take two photos and combine them into one. This can be done with film or digital cameras.
You can create double exposure photos by taking two separate photos and then combining them in an editing program. You can also use a special function on some digital cameras that will let you take two exposures in one photo.
What’s The Difference Between ISO and Exposure?
ISO and exposure are both terms used in photography. They are both measures of how much light hits your sensor. However, they are measured in different units. ISO is a measure of your camera sensor’s sensitivity to light, while exposure is a measure of the amount of light hitting your sensor.
Checking Exposure On Your Histogram
Once you’ve taken a photo, you can check the exposure by looking at the histogram. The histogram is a graph that shows how much light is in your photo. If the graph is all the way to the right, then your photo is overexposed. If the graph is all the way to the left, then your photo is underexposed. If the graph is in the middle, then your photo is properly exposed.
How To Capture The Right Exposure
Now that we’ve covered the essentials about exposure, let’s dive into how you can capture the right level of exposure in your photos.
Aperture priority, shutter priority, manual mode
These are all different ways that you can control exposure.
Aperture priority lets you choose the aperture, and the camera will choose the shutter speed.
Shutter priority lets you choose the shutter speed, and the camera will choose the aperture.
Manual mode lets you choose both the aperture and shutter speed.
If you’re shooting high action photos and don’t have the time to manually adjust your settings on the fly, it’s recommended to leverage the aperture or shutter priority modes on your camera, based on your shooting situation.
Using The Right Equipment
If you want to have more control over exposure, then you need to use the right equipment. A DSLR camera will give you more exposure options than a point-and-shoot camera.
A tripod will also help you get the right exposure by keeping your camera still when using slow shutter speeds.
And lastly, a remote shutter release will let you take photos without touching your camera, which can help prevent camera shake.
Adjusting Camera Modes
You can also leverage other types of camera modes to get the most out of your photos and avoid mistakes with your exposure levels.
Portrait Mode: This mode is great for taking photos of people. It will help you get a shallow depth of field, which means the background will be blurry and your subject will be in focus.
Landscape Mode: This mode is perfect for taking exposure photos because it sets a small aperture to make sure everything in your photo is in focus.
Night Mode: This mode is designed for taking photos in low light situations. The camera will use a slow shutter speed, so it’s important to use a tripod to avoid blurry photos.
Sports/Action Mode: This mode is perfect for taking photos of moving subjects. It will use a fast shutter speed to freeze the action.
Post-Processing Exposure
Once you’ve taken your exposure photos, you can further adjust the exposure levels in post-processing. This can be done with an editing program like Adobe Photoshop or Lightroom.
In Photoshop, you can use the Levels or Curves tools to adjust the exposure. In Lightroom, you can use the Exposure slider to make adjustments.
Just remember that you don’t want to go too far in either direction. If you make your photo too dark, it will be underexposed. If you make your photo too light, it will be overexposed.
You can also use exposure blending to combine two exposure photos into one. This is a great way to get the perfect exposure, especially if you’re shooting in difficult lighting conditions.
Exposure blending is a technique where you take two photos of the same scene at different exposure levels and then blend them together. This can also be done by hand or by using an editing program like Photoshop or Lightroom.
There are many different ways to blend exposures, but the most common way is to use the Lighten or Darken blending modes.
What Is Good Exposure In Photography?
An excellent photo exposure is generally the proper balance of aperture, shutter speed, and ISO that best depicts the subject you are trying to capture. Think of light and exposure in photography as filling a bathtub with water. The amount of water your curtains open is controlled by your aperture, while your shutter speed determines how long you leave them open. Your ISO setting determines how big your tub is. These settings are proportional, which means they don’t exist in a single combination that would give you the ideal exposure.
It’s all about figuring out how much light you need to see what you want. You’ll want to shoot at a slower speed than usual, such as 1/100 or 1/60 second, in order to let in the same amount of light as if you were shooting at 1/25 or 1/11 seconds. These settings will produce identical exposures, however things like depth of field will be different.
It is up to you to pre-visualize your photograph and determine how you wish to portray components like depth of field and choose the exposure settings that allow enough light into the image so that some detail may be seen and vibrant colors may be rendered that are acceptable with you.
Conclusion
Exposure is an important aspect of photography, and it’s something that every photographer needs to understand.
Now that you know what exposure is and how to use it, you’ll be able to take better photos in any situation. Just remember to practice and experiment with different exposure levels to find what works best for you.
