Adaptive skill practice — find your level, get sharper.
Photography practice
Expose, focus, and compose a photograph
Learn how a photograph actually works — the exposure, optics, light, and composition a photographer reasons about. The exposure triangle (aperture, shutter, ISO), stops and EV, reciprocity and equivalent exposure, and the sunny-16 rule; aperture and depth of field, bokeh, and diffraction; freezing vs blurring motion and flash sync; ISO and noise; focal length, perspective compression, crop factor and equivalent focal length, and hyperfocal distance; color temperature and white balance; the inverse-square law and flash guide numbers; the rule of thirds, leading lines, framing, and negative space; and RAW vs JPEG, histograms, and dynamic range. Many exposure and optics questions have a computed, always-correct answer, and every explanation names the classic mix-up and leaves you a rule for the next shot. Skill practice in a craft, from your first manual exposure onward — whether you shoot on a phone, mirrorless, or DSLR.
