This article covers what it means for your photo to be exposed and the different solutions to fix underexposed photos. We'll also be reviewing how to avoid underexposure when shooting pictures. Now that you're aware of what this article covers, let's begin.

Part 1. What Is An Underexposed Photo And Why?

Some people don't understand what it means for their pictures to be underexposed. Let's check out what an underexposed photo is and what could be causing you to have underexposed photos.

What's an underexposed photo?

The photographer usually determines an underexposed photo. It depends on the artistic interpretation as the photographer gets to decide if the picture is underexposed or not. An underexposed image is usually when a photo turns out darker than the photographer wanted. Dark and moody photography would disagree with the airy photographer on what an underexposed photo is. However, there are moments when the images are as underexposed that there's no way it's intentional. Simply put, any photo that needs to brightening is simply underexposed.

Why photos underexposed?

Knowing why your photos are underexposed can be the key to fixing the issue. The goal of photographers is to get perfect shots every time they shoot on their camera. Having an idea of why photos are underexposed will help you prevent the scenario another time. Below are some reasons why photos turn out underexposed.

Wrong Exposure

One of the reasons you might be experiencing underexposed photos is the wrong exposure when shooting. Sometimes, the lighting changes in your environment, and you have to compensate for it through your camera setting. Also, when you tweak your settings, it is unfavorable to your scene, which leads to underexposed photos. It could be an error you're not aware of. However, when your pictures are underexposed, you should first check your exposure settings.

Flash Settings

Flash settings generally tend to make pictures dack. There are moments when the shutter speed is too fast for the flash to keep up, or your flash simply didn't go off. It could be a pop-up flash or even an on-camera flash. If the former is the case, then it has a high chance of affecting your image. Your flash setting could also be relatively low, which is a top reason for underexposed images.

Sometimes, the subject has ample light while the background is too dark. When combined with the flash exposure to the subject and not the environment, the result would be underexposed photos. Also, we have article related with overexposed photos.


Even if the flash and the exposure setting are correct, you could still get dark photos because of your metering mode. If the image background is too dark or too bright, it could be hard for the camera sensor to read. This situation could lead to incorrect reading and, therefore, an underexposed photo. If you check your exposure setting and your flash setting and everything seems okay, then the problem might just be with your metering mode.

Part 3. Tips to Avoid Underexposure Again

Just like underexposure is caused by a couple of factors, there are some actions you can take to avoid underexposure in your photos, and they are:

Add light to the subject

The best way to add light to the subject is with your flash. It could be an external flash or the inbuilt one to your camera. You can also utilize a large white reflector, but that could be stressful. Alternatively, try shooting in a well-lit area to avoid underexposed photos.

Alter the camera's ISO setting

You get to decide how much light your camera needs to get exposure. One way to do this is by setting the ISO number higher, so the camera sensor is more sensitive to light. Ensure you don't alter any other setting, and this will prevent underexposure in your photos. The downside to this is the possibility of a decline in sharpness. You might also notice an increase in digital noise.

Open the 'Lens Aperture'

The lens aperture is like a window to your camera. The wider it opens, the more light gets into your camera and brightens up the scene. You can change the aperture opening of your camera, but you can't do this on auto mode. You have to switch to aperture priority mode to get it done, and it will prevent underexposure in your photos.

Reduce the shutter speed

It works with the lens aperture, so this solution works as an alternative to opening the lens aperture wider. Instead of opening the lens aperture, you can change the shutter speed. This action increases the length the aperture stays open and will increase your exposure. You can alter the shutter speed in your setting, and you don't have to leave the auto mode on your camera.

Override the camera's exposure setting

There's a feature in your camera setting that allows you to override the exposure setting. It is either located on the LCD screen on the camera's back or somewhere else. You can check the manual that comes with your camera for a guide on how to get it done.
