Photography: Light, Contrast, and Frame
Like Duolingo, but for Photography: Light, Contrast, and Frame. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Controlling the Frame and Intent and Reading and Shaping Available Light. It assumes you already know the basics.

Key ideas in Photography: Light, Contrast, and Frame
- In-camera meters calculate exposure by averaging light down to 18% gray.
- A predominantly white frame tricks the meter into underexposing the shot.
- Scenes with deep black backgrounds fool meters into overexposing shadows.
- Spot metering measures light from a tiny, targeted circle in the frame.
- Metering a highlight forces darker ambient surroundings to drop to pure black.
- This exposure method preserves highlight textures while clipping cluttered shadows.
- Dialing negative exposure compensation protects dramatic, moody darks.
- Dialing positive exposure compensation prevents bright whites from turning dull gray.
- High-key imagery relies on intentional overexposure relative to the meter's neutral mark.
- The rear LCD brightness shifts automatically based on outdoor ambient light.
- A histogram wall on the right indicates absolute highlight clipping.
- LCD previews display processed JPEGs rather than the true RAW data limits.
- ETTR pushes histogram data as far right as possible without clipping highlights.
- Collecting maximum light gives shadow areas a superior signal-to-noise ratio.
- ETTR images require pulling exposure back down during RAW post-processing.
- Telephoto compression magnifies distant background elements relative to the subject.
