**Multispectral imaging.** Several layers per pixel — one **channel** for each wavelength band. - Each channel samples a **different wavelength range**, achieved with different filters over the detectors. - Stored as a stack: each pixel is a *vector* of values (one per band). - Enables band math (ratios, indices like NDVI) and classification. - **Example color film split:** 0.4–0.5 µm blue, 0.5–0.6 µm green, 0.6–0.7 µm red.
