To take better photos, decide what the picture is about, frame that subject deliberately, and choose exposure settings that suit the motion and depth of field you want. The rule of thirds is a useful framing experiment—not a rule every good photo must follow—and phones, point-and-shoots, and interchangeable-lens cameras can all be used to practice.
How do you take better photos?
Start by identifying the subject: what should a viewer notice first? Composition is the choice of how to frame the picture and show that subject. Nikon describes it as “how you choose to frame the picture you’re about to make” in its guide to 5 Easy Composition Guidelines.
- Make a first frame around your subject.
- Check the edges and background for distractions, such as bright objects or clutter that pull attention away.
- Make another frame while changing just one choice: move your position, shift the subject within the frame, or leave more space around it.
- Compare the two pictures. Notice which better directs attention to the subject and why.
This small comparison is more useful than trying to memorize a formula. Composition guidelines can help you make a choice, but they do not guarantee a successful picture.

Imagine the frame divided into nine equal rectangles by two evenly spaced vertical lines and two evenly spaced horizontal lines. To try the rule of thirds, place a subject on one of those lines or near an intersection. For a landscape, you might place the horizon along a horizontal line rather than directly across the center, if that gives the scene a more intentional balance.

Many cameras and phone-camera apps offer a grid overlay, though the setting and menu path vary by device. If your camera has one, use it as a framing aid; otherwise, picture the divisions mentally. The National Park Service’s composition guide and Fujifilm’s composition guide describe placing a subject along a line or at a cross section.
Then take a second version with the subject centered or with a different amount of open space. Compare which placement fits the subject and scene. The thirds grid is a starting point, not a law: a centered subject, a deliberately unbalanced frame, or another arrangement may better express what you want to show.
How do aperture, shutter speed, and ISO work together?
Shutter speed, aperture, and ISO affect image brightness, but each also changes how the photograph looks. Fujifilm describes them as a trio of exposure controls in its exposure guide. Rather than searching for one universally correct setting, choose based on the result you want, then balance the other controls.

|---|---|---|---|
| Shutter speed | Changes how movement is rendered. | Use a faster shutter to reduce blur from moving subjects; use a slower one to blur moving water. | A slower shutter makes camera steadiness more important. |
| Aperture | Changes the opening that admits light and affects depth of field—the range that appears in focus. | A lower f-number means a wider opening and can make the in-focus area shallower; a higher f-number can keep more of a scene in focus. | The best choice depends on whether you want a shallow or deeper in-focus area, as well as the exposure you need. |
| ISO | Changes the camera’s sensitivity setting and can help brighten a low-light exposure. | Raise ISO when needed to get the shutter speed or aperture the scene calls for. | Higher ISO can make image noise more visible. |
These are practical tendencies, not isolated effects: changing one control can lead you to adjust another to maintain brightness. Aperture also does not determine background blur by itself; the overall scene and camera setup matter. The National Park Service guide explains the relationship between aperture and depth of field, shutter speed and motion, and ISO and noise.
What camera setting should you learn first?
Learn to connect a setting to a visible effect rather than memorizing a fixed order or default number. If a subject is moving and you want it sharp, begin by thinking about shutter speed. If you want more of a scene in focus, think about aperture. In dim light, ISO may help you get the exposure you need, but inspect the image for noise.
- Photograph a stationary subject and note the framing and exposure.
- Photograph a moving subject. Try a faster shutter and check whether movement looks less blurred.
- If your camera allows manual aperture changes, take a similar frame with a lower and a higher f-number. Compare how much of the scene appears in focus.
- In lower light, raise ISO only as needed and inspect the result at normal viewing size for visible noise.
- Change one control at a time when possible, so you can see what changed. If your camera is in an automatic mode, use an available priority or manual mode to explore the controls; exact mode names depend on the camera.
Phone cameras often automate some or all of these settings, but you can still practice observing motion, focus, brightness, and noise. The National Park Service notes that its basic guidance applies to DSLR, point-and-shoot, and phone cameras; it does not require a particular camera purchase.

Try photographing the same subject in different light when practical. The National Park Service describes golden-hour light as softer and more even than harsh direct sunlight, which can create strong shadows or overexposure. Treat that as one useful condition to test, not a universal best time: weather, location, season, and the subject all affect the result.
Compare where shadows fall, whether bright areas lose detail, and how the light helps or distracts from your subject. A change in position or framing may improve a photo even when the light itself cannot be changed.
