Get the perfect photo with your smartphone camera’s manual settings

The best camera phones offer a similar photography experience to many dedicated cameras. But they can fail to capture a scene the way you would expect. Many Android devices allow you to dial in the look of your photos with manual camera settings. You can adjust the aperture and shutter speed or play with white balance and focal length to capture the perfect shot. We walk you through a list of common manual camera settings, what they do, and how to use them.

Does my phone have manual camera settings?

Not every phone provides access to its manual camera settings, but many do. Many Samsung phones are compatible with the company’s Expert RAW app, which presents several manual settings. OnePlus’s recent Hasselblad-branded flagships, like the OnePlus 12, have a camera mode that works similarly. Sony flagships like the Xperia 1 V do their best to imitate Sony’s dedicated Alpha cameras with the Photo Pro app.

Google Pixel phones don’t provide full access to the manual camera settings. Instead, they present sliders in the camera viewfinder to adjust brightness, shadows, and warmth independently. Several manual camera apps are available through the Play Store, but many of them are bad, offering spotty feature compatibility across phone models. If your phone’s manufacturer doesn’t provide a dedicated manual camera app, chances are you can’t easily shoot with manual settings.

How do manual camera settings work?

When you tap the shutter button on your phone’s camera app, the camera captures what’s in front of you as it appears to your eyes. While that experience is mostly automatic from your end, the phone does a lot of work in real time to figure out what the resulting photo should look like. You can do that work with manual camera settings and customize how your photo looks.

Terminology and where each setting is located vary from device to device, but the principles of how they work are universal. Here are the most common manual camera settings, what they do, and how to use them.

Shutter speed

In mobile photography, shutter speed is a measure of how long your phone’s image sensor gathers light to create a photo. (Phones don’t have shutters, so you might see this setting referred to as speed.) Shutter speed is represented as a fraction. For example, 1/60 means the image sensor gathers light for one-sixtieth of a second.

Slower shutter speeds gather more light. A photo taken at a shutter speed of 1/100 is brighter than one taken at 1/500. Your phone combines everything it sees while the image sensor collects light into one image, so slow shutter speeds are also prone to motion blur. This balance can make choosing a shutter speed tricky. As a rule of thumb, darker environments require slower shutter speeds, and brighter settings require faster shutter speeds.


The ISO setting adjusts how sensitive the image sensor is to incoming light (ISO stands for International Organization for Standardization, a term that dates back decades to film photography). Higher ISOs result in brighter images and increased noise, the discolored, grainy quality seen in some photos taken in dark settings. A low ISO results in a darker photo with less visible noise.

Balancing ISO and shutter speed is important for getting good photos across lighting conditions. A higher-than-usual ISO can brighten photos taken in the dark, which means you can shoot at a faster shutter speed to reduce motion blur on moving subjects. You’ll need to be mindful of noise, though.


EV stands for exposure value. On dedicated cameras, EV is calculated from shutter speed and aperture settings. Smartphone cameras don’t typically have moving apertures. The EV setting in mobile photography deals with shutter speed and ISO.

The EV slider adjusts the shutter speed and ISO to change the brightness of your photo. Lowering the EV in the phone’s manual camera settings makes the resulting photo darker. Raising the EV makes the photo brighter. Conversely, adjusting either the shutter speed or ISO changes the EV. This can be handy if you want a brighter or darker image but don’t know how to change the other two settings.

White balance

White balance (often abbreviated WB in manual settings) controls the color temperature in your photos. It’s measured in Kelvin (abbreviated as K). Setting the white balance to a lower number makes a picture visibly cooler (more blue). Setting the white balance higher makes the image warmer (more orange).

Different light sources emit light in different colors. Outdoor light on a sunny day doesn’t look the same as indoor light from artificial sources, and different types of light bulbs produce differing colors of light. To get a natural-looking image, adjust the white balance to compensate for the lighting conditions you’re shooting in.

Pro photographers have tools and techniques for getting the perfect white balance. In recreational photography, it’s fine to eyeball it. When dialing in WB, compare colors in the image on your phone’s screen to what you see in real life and match the two. White objects are helpful to gauge white balance, as color temperature differences look most pronounced there.

Smartphones generally rely on autofocus to pick which part of the frame should be in focus. You can tap other areas to change where the camera focuses, but manual settings let you dial in focus with more granularity.

Manual focus on smartphones is controlled with a slider. The low end of the slider sets the plane of focus close to the camera. The high end focuses far away. Manual focus might be an appealing option when trying to get a sharp photo of something too small for autofocus to reliably zero in on.
