Key Takeaways
- Grid lines, exposure lock, and RAW format are built into most phones but rarely used by default.
- Simple setting changes like adjusting white balance or enabling manual focus can visibly improve photo quality.
- You do not need photography experience to benefit from these controls; they are designed for everyday use.
- Shooting in RAW preserves more image data, giving you more flexibility when editing photos later.
- Most of these settings are free, already on your phone, and take under a minute to find.
What auto mode leaves on the table
Your phone's camera does a lot of work automatically: it sets the exposure, picks a focus point, chooses the white balance, and applies noise reduction before you even tap the shutter. For quick snapshots, that pipeline is convenient. For photos you actually want to keep, it often guesses wrong in ways that are easy to fix once you know where to look.
The settings below are available on most Android and iPhone models and do not require a photography background to use. If you are still getting comfortable with your phone more broadly, the beginner's guide to smartphones covers the basics that make everything else easier to navigate.
Grid lines for better composition
Most camera apps include an optional grid overlay, usually a three-by-three or square guide, that appears on screen while you frame a shot. It does not appear in the final photo.
The grid helps you apply the rule of thirds: placing your subject near one of the four intersection points rather than dead-center tends to produce a more balanced image. It also helps you keep horizons level, which is harder than it sounds without a reference line. On iPhone, go to Settings, then Camera, and toggle Grid on. On Android, the option is usually inside the camera app itself under settings.
A grid overlay does not affect the photo but consistently improves framing.
Exposure lock (AE/AF lock)
When you tap the screen to focus, your phone also sets the exposure for that spot. In mixed lighting, this leads to blown-out skies, dark faces, or washed-out details because the camera is optimizing for wherever you tapped, not the full scene.
On both iPhone and most Android devices, a long press on the subject you want to expose for activates AE/AF lock (auto exposure and auto focus lock). The phone freezes both settings so they do not shift as you reframe. This one habit eliminates a large share of over- or underexposed shots in outdoor and window-lit scenes.
Locking exposure stops the camera from re-guessing as you move the frame.
Exposure compensation slider
Even when the automatic exposure is close, it often is not quite right. Most camera apps show a small sun or brightness icon after you tap to focus; dragging it up or down adjusts the exposure without locking it entirely.
Sliding it down by about half a stop in bright outdoor light preserves detail in clouds and highlights. Sliding it up in shaded or indoor scenes brightens the subject before the phone resorts to a high ISO (the sensor's sensitivity setting), which adds visible grain. This slider is one of the fastest ways to improve a photo with a single motion.
A small exposure adjustment before you shoot beats fixing a dark or washed-out photo later.
White balance control
Auto white balance removes unwanted color casts most of the time, but it can be slow to update and occasionally wrong in mixed lighting, for example a room lit by both fluorescent overhead lights and warm lamps. The result is a photo that looks orange, green, or blue in ways that editing struggles to fix evenly.
Many camera apps, especially on Android, let you set white balance manually or pick a preset (daylight, cloudy, incandescent, fluorescent). If your indoor photos consistently look too warm or too cool, switching to a fixed preset for the shooting environment gives you a consistent baseline that is easier to work with.
Fixing white balance before you shoot is faster than correcting color casts in editing.
RAW format for photos you plan to edit
JPEG (the default format) is processed inside the phone before it saves: the camera applies sharpening, noise reduction, and color adjustments, then discards the original sensor data. RAW files skip that processing and save the raw sensor data instead, which is a larger file but one that retains far more detail in shadows and highlights.
If you use any photo editing app, shooting in RAW gives you considerably more room to recover an underexposed shot, fix white balance, or pull detail from bright areas. Most iPhones support Apple ProRAW (found in Settings under Camera and Formats). Many Android devices support a standard RAW or DNG option through the Pro or Manual mode in the camera app. RAW is not worth enabling for quick social media shots, but for anything you care about, it changes what is recoverable later.
RAW files keep data that JPEGs permanently discard, giving you more to work with when editing.
Manual focus for close-up shots
Autofocus works well at normal distances but often hunts or locks onto the wrong subject when you are close to a small object, such as food, a product label, or a flower. Many camera apps include a manual focus slider in their Pro or More settings tab.
Pulling the slider to the near end and then slowly adjusting toward your subject lets you place focus exactly where you want it, with no hunting. Some apps also display a focus peaking overlay, where in-focus edges appear highlighted in a color, making precise manual focus much easier to judge on a small screen.
Manual focus stops the camera from hunting when you are photographing something close up.
Timer and burst mode
The two-second or ten-second self-timer is not just for selfies. Tapping the shutter with your finger introduces micro-movement at the moment of capture; setting a two-second delay lets the phone stabilize after you tap, which noticeably sharpens photos taken in low light or on an improvised surface.
Burst mode, activated by holding the shutter button down, captures a rapid sequence of frames. It is useful for photographing moving subjects (children, pets, sports) where a single frame often catches the wrong moment. Most phones let you select the best frame from the burst afterward and discard the rest, so storage is not a lasting concern.
A two-second timer eliminates shutter-tap shake without any additional equipment.
Making these settings part of your normal routine
None of these controls require you to stay in a manual mode forever. Most people settle on two or three that match the situations they photograph most often, then leave the rest alone. If you shoot a lot indoors, locking exposure and adjusting white balance will do the most. If you want more editing flexibility later, RAW is worth enabling once and forgetting about.
Start with one setting at a time
Changing multiple camera settings at once makes it hard to know which adjustment helped. Pick one from this list, use it for a week across different lighting situations, then decide whether to keep it. This approach builds familiarity without requiring you to learn everything at once.
