What is the difference between DSLR, mirrorless, and compact cameras?

DSLRs use an optical viewfinder and interchangeable lenses; mirrorless cameras also accept interchangeable lenses but are usually smaller; compact cameras are portable all-in-one models.

How do aperture, shutter speed, and ISO affect a photo?

Aperture controls depth of field and light, shutter speed controls motion blur, and ISO adjusts sensor sensitivity in darker conditions.

Which focus mode should I use for moving subjects?

Use continuous autofocus, often called AF-C or AI Servo, so the camera keeps tracking a moving subject.

Shutter priority: controlling motion; fast shutter speeds to freeze action
Metering modes and typical default (often evaluative/matrix metering)
ISO purpose: adjusting sensor sensitivity for exposure vs noise trade-offs
Focusing modes, including continuous AF (AF-C/AI Servo) for action

About the free online course

Want to take photos you’re proud to share, but feel lost in camera settings and confusing buttons? This beginner-friendly photography course helps you move from guesswork to confident shooting by explaining how cameras actually work and how to make smart choices in real situations. Whether you use a DSLR, a compact camera, or a mirrorless model, you’ll learn what makes each type different and how to pick gear that fits your goals, budget, and style of shooting.

You’ll start by building a clear foundation: how to set up your camera, what the mode dial is for, and how common shooting modes affect your results. Then you’ll connect the key exposure controls so they finally make sense together. You’ll see how aperture influences brightness and depth of field for soft backgrounds, how shutter speed can freeze action or reveal motion, and how ISO helps you adapt to low light while managing image noise.

As you practice, you’ll also learn to read the information in your viewfinder and use tools that photographers rely on every day. Discover how metering modes shape exposure decisions, how exposure compensation helps when the camera’s reading is fooled by bright or dark scenes, and how focusing modes change the way your camera tracks movement. Simple tips on tripod technique will help you produce sharper images, especially in low light or when using slower shutter speeds.

Finally, you’ll make sense of lenses by comparing zooms and primes, so you can choose focal lengths that match the subjects you love—travel moments, portraits, or fast-moving scenes. By the end, you’ll be able to set up quickly, adjust settings with purpose, and create more consistent, intentional photographs in everyday conditions.
