Photography Basics
What is metering?
They balance exposure: widening aperture or slowing shutter speed lets in more light, as does raising ISO, but each affects depth of field, motion, and noise.
Formats include JPEG (compressed, web-ready), RAW (editable), PNG (lossless, transparent), and TIFF (high-quality print).
A DSLR (Digital Single-Lens Reflex) uses a mirror and optical viewfinder to show the exact scene seen by the lens before capture.
Metering measures scene light for correct exposure; modes include evaluative, center-weighted, and spot.

What is the purpose of the camera lens?
Post-processing adjusts exposure, color, contrast, and cropping in software like Lightroom to enhance images without altering reality.
The lens focuses light rays onto the sensor or film to form a sharp image, with different focal lengths affecting field of view.
A tripod stabilizes the camera to prevent shake, essential for long exposures, low light, or sharp macro shots.
ISO measures sensor sensitivity to light; low ISO (e.g., 100) for bright conditions, high ISO (e.g., 3200) for low light but with more noise.

What is the difference between analog and digital photography?
Symmetry centers subjects evenly for balanced, formal images, often using reflections or architecture.
Analog photography uses film to chemically record light, while digital photography uses electronic sensors to capture and store images as data files.
The sensor converts light into electrical signals, creating a digital image; larger sensors like full-frame capture more light and detail.
Modes include Auto (camera decides), Program (P, auto exposure balance), Aperture Priority (Av), Shutter Priority (Tv), and Manual (M, full control).

What is basic post-processing?
Natural light comes from the sun or sky; golden hour (sunrise/sunset) provides soft, warm illumination.
The exposure triangle consists of aperture , shutter speed , and ISO , which together control the brightness and quality of an image.
Post-processing adjusts exposure, color, contrast, and cropping in software like Lightroom to enhance images without altering reality.
Modes include Auto (camera decides), Program (P, auto exposure balance), Aperture Priority (Av), Shutter Priority (Tv), and Manual (M, full control).
Photography Basics
What is shutter speed?
Photography is the art and science of creating images by recording light, either electronically using digital sensors or chemically using film.
Modes include Auto (camera decides), Program (P, auto exposure balance), Aperture Priority (Av), Shutter Priority (Tv), and Manual (M, full control).
Shutter speed is the time the shutter remains open, measured in seconds or fractions; fast speeds freeze motion, slow ones blur it.
Autofocus automatically adjusts lens focus; single (AF-S) for static, continuous (AF-C) for moving subjects.
Photography Basics
What are the main shooting modes?
Noise is grainy artifacts from high ISO or long exposures; reduced by lower ISO, noise reduction, or better sensors.
Modes include Auto (camera decides), Program (P, auto exposure balance), Aperture Priority (Av), Shutter Priority (Tv), and Manual (M, full control).
Exposure is the total light reaching the sensor, determined by aperture, shutter speed, and ISO for proper image brightness.
Manual focus lets the photographer turn the lens ring for precise control, useful in low light or macro.

What are common file formats for photos?
Bokeh is the aesthetic quality of blurred out-of-focus areas, achieved with wide apertures and long lenses.
Symmetry centers subjects evenly for balanced, formal images, often using reflections or architecture.
Formats include JPEG (compressed, web-ready), RAW (editable), PNG (lossless, transparent), and TIFF (high-quality print).
The rule of thirds divides the frame into a 3x3 grid, placing key elements along lines or intersections for balanced, dynamic compositions.
