wunder beta📷 Photography Basics
Master light, focus, and composition to make photographs you love.
What you’ll learn
- Control exposure using aperture, shutter speed, and ISO.The exposure triangle balances aperture, shutter speed, and ISO. Aperture controls depth of field, shutter speed controls motion, and ISO controls sensitivity and noise, each also affecting brightness.
- Compose stronger images using framing techniques and light.Composition tools like the rule of thirds, leading lines, and framing guide the viewer's eye, while understanding the quality and direction of light turns ordinary snapshots into memorable photographs.
Questions this course answers
What three settings make up the exposure triangle?
The exposure triangle consists of aperture, shutter speed, and ISO, which together control exposure.
A wide aperture like f/1.8 produces what effect?
A wide aperture (small f-number) lets in more light and creates a shallow depth of field, blurring the background.
What is the main downside of using a very high ISO?
Raising ISO increases sensitivity but also introduces digital noise, degrading image quality.
The rule of thirds suggests placing your subject where?
The rule of thirds places key elements along a nine-part grid's lines or intersections for a more balanced image.
What are 'leading lines' used for in composition?
Leading lines like roads or rivers guide the viewer's eye through the frame toward the subject.
Why do many photographers favor the golden hour?
Golden hour, just after sunrise and before sunset, offers warm, soft, low-angle light that is flattering for most subjects.
