Using the wrong lens Camera shake from handholding Shooting in JPEG format Having too many megapixels Camera shake transfers vibration from the photographer's hands into the camera during the exposure, causing the entire image to blur in the direction of movement. Even small amounts of movement at slow shutter speeds produce visible softness across the whole frame. What is the classic rule of thumb for minimum shutter speed when handholding? Always use at least 1/500 second Match the shutter speed to the ISO Use at least 1 over your effective focal length Use at least 1/60 second regardless of lens Shutter speed determines how long the sensor collects light. A fast shutter (like 1/1000 second) freezes motion and reduces exposure. A slow shutter (like 1 second) allows movement to blur and accumulates more light over time. It is your primary tool for controlling how motion appears in your image. For a 200mm lens on an APS-C body with 1.5x crop factor, what effective focal length should you calculate for? 200mm 150mm 300mm 400mm A lens bends light and focuses it onto the sensor. Different lenses bend light at different angles, giving different fields of view. Prime lenses (fixed focal length) tend to be sharper and faster; zoom lenses offer flexibility and convenience. What breathing technique helps maximize sharpness when shooting handheld? Hold your breath for as long as possible Breathe rapidly to stay alert Exhale halfway, then shoot during the natural pause between breaths Inhale deeply just before pressing the shutter Sharpness depends on focus, aperture, shutter speed, ISO, lens quality, and camera stability. A sharp image shows fine detail and contrast. Oversharpening in post-processing can add artifacts and look unnatural. How many stops of improvement can a good image stabilization system provide? 1 to 2 stops 3 to 5 stops 6 to 8 stops 10 or more stops Image stabilisation systems sense rotational movement and apply an equal and opposite correction to an optical element or the sensor. Compensating for the equivalent of three to five stops of shutter speed means a photographer can handheld shoot at speeds that would otherwise produce visible camera shake. What is the recommended approach to image stabilization? It replaces the need for fast shutter speeds entirely Think of it as a safety net rather than a replacement for adequate shutter speed Turn it off when using a tripod Both B and C are recommended Image stabilisation compensates for camera shake but cannot freeze subject movement. Treating it as a tool that extends the range of workable shutter speeds, rather than a substitute for correct technique, uses it appropriately. Turning it off on a tripod prevents the system from introducing micro-corrections to a camera that is already stationary. For consistently sharp results, how fast should your shutter speed be relative to the minimum rule? Exactly at the minimum Two to three times faster than the minimum Half the minimum speed Ten times faster than the minimum Shutter speed determines how long the sensor collects light. A fast shutter (like 1/1000 second) freezes motion and reduces exposure. A slow shutter (like 1 second) allows movement to blur and accumulates more light over time. It is your primary tool for controlling how motion appears in your image. How should your left hand be positioned when holding the camera for maximum stability? Gripping the top of the lens Resting on the camera body Cradling the bottom of the lens, supporting its weight Held out to the side for balance The lens is the heaviest part of the camera-lens system, and its weight should be supported directly rather than hanging from a grip on the camera body. A hand cradling the bottom of the lens creates a stable platform and reduces the lever-arm effect that makes a heavy lens difficult to hold steadily. Restart quiz
