An aperture ring lets photographers control the lens aperture directly from the lens barrel. Learn how it works and why some photographers still prefer it.

Many camera kit lenses have a variable maximum aperture. Learn why the f-number changes as you zoom and what it means for exposure and video.

Log video profiles are designed to preserve more tonal information for grading. Learn what Log does, its trade-offs and whether a YouTube creator actually needs it.

Hyperfocal distance is a focusing concept used to maximise the apparent depth of field. Learn what it means and when it is useful for landscape and street photography.

Stopping down the aperture can increase depth of field, but very small apertures can introduce diffraction. Learn what it is and how it affects real photographs.

Exposure bracketing lets you capture the same scene at different exposure levels. Learn how it works, when it helps and why it is useful for difficult lighting.

Focus stacking combines photographs taken at different focus distances to create greater apparent depth of field. Learn when it helps and when you do not need it.

Have you ever taken a photograph that looked normal to your eyes but came out noticeably blue, orange or green? White balance is often the reason. It tells the camera how different light sources should appear so that neutral objects look neutral and other colours remain more natural. Why different light sources have different colour Daylight, indoor bulbs, shade and fluorescent lighting do not all have the same colour characteristics. Human vision adapts quickly, so your eyes

When you take a photograph, your camera may let you save it as JPEG, RAW or both. The choice is not about one format being universally better. It depends on how you plan to use the photograph. What Is JPEG? JPEG is a processed image format. The camera applies processing such as colour, contrast, sharpening, noise reduction and white balance before saving the image. The result is convenient for quick sharing and everyday photography. What Is RAW? A RAW file keeps much more of

Minimum shutter speed affects handheld sharpness, motion blur and Auto ISO behaviour. Learn how to choose it for different photography situations.

Sensor readout speed can affect rolling shutter and fast-moving subjects. Understand why it matters when comparing cameras for video.

What Is Exposure Compensation on a Camera and When Should You Use It? Exposure compensation is one of the most useful camera controls for photographers who use automatic or semi-automatic exposure modes. It lets you tell the camera that you want the final photograph to be brighter or darker than the exposure the camera has selected. Why Would You Change Exposure Compensation? Camera metering is designed to make an exposure based on the scene it sees. Very bright or very dark

What Is a Camera Metering Mode? Your camera constantly evaluates the light in a scene to help determine exposure. Metering modes change how the camera gives importance to different areas of the frame. Evaluative or Matrix Metering This mode evaluates multiple areas of the frame and uses the overall scene to calculate an exposure. It is designed as a general-purpose option and is commonly useful for everyday photography. Center-Weighted Metering Center-weighted metering gives

What Is a Camera's EVF Blackout? When shooting rapidly with an electronic viewfinder, some photographers notice that the viewfinder briefly changes or becomes difficult to use between frames. This can be related to viewfinder blackout or display behaviour during continuous shooting. Why Can It Happen? During image capture and processing, the camera may temporarily alter what is displayed through the electronic viewfinder. The exact behaviour depends on the camera design, shoo

What Focal Length Should You Use for Portraits, Travel and Wildlife? One of the easiest ways to become confused when buying a lens is looking only at the focal length number. 18mm, 35mm, 50mm, 85mm and 200mm can all be useful, but they serve different purposes. Wide Focal Lengths Shorter focal lengths are useful when you need more of the scene inside the frame. They can work well for landscapes, architecture, travel, interiors and vlogging, especially when you cannot physical

RAW and JPEG are not simply two different image-quality settings. They are two different ways of storing the information captured by a camera. Understanding the difference helps you choose the right format for travel, everyday photography, editing, social media and important shoots. What a JPEG file does A JPEG is processed inside the camera before it is saved. The camera applies decisions about sharpening, contrast, colour, noise reduction and other image characteristics, th

Aperture is one of the three main exposure controls in photography, but its effect goes beyond making a photograph brighter or darker. The aperture setting also influences depth of field and the appearance of the background. Understanding f-stops makes it easier to choose lenses and camera settings based on the photograph you want to create. What does aperture mean? Aperture is the opening inside a lens through which light passes to the camera sensor. It is expressed using f-

Focal length is one of the most important lens specifications, yet it is often reduced to a simple question of how much the lens can zoom. In practice, focal length changes the field of view, working distance and the way a scene is framed. Choosing the right focal length starts with understanding what you photograph and how close you normally stand to the subject. What focal length actually changes A wide focal length shows more of the scene, while a longer focal length shows

Megapixel count is one of the first specifications people notice when comparing cameras, but it is often misunderstood. A higher resolution can be useful in certain situations, yet it does not automatically mean that every photograph will look better. What Megapixels Actually Represent Megapixels describe the number of pixels captured by the camera sensor. More pixels can provide additional detail and greater flexibility when cropping an image, especially when the photograph

Choosing between a prime lens and a zoom lens is not simply a question of which type is better. Each design solves different photographic problems, and the right choice depends on how you work. What Is a Prime Lens? A prime lens has one fixed focal length. You change framing by moving yourself rather than turning a zoom ring. Many primes offer wide maximum apertures, which can be useful for portraits and low-light photography. What Is a Zoom Lens? A zoom lens covers a range o
