Camera & Exposure
ISO
The amplification applied to your sensor’s signal. Low ISO (100–400) = clean image. High ISO = brighter but noisier, like turning up a quiet recording until you hear hiss.
On drones and phones with small sensors, noise arrives fast — keep ISO as low as the light allows and add real light (or a slower shutter) before you add gain.
Why it matters for your listings
Grainy twilight footage reads as cheap. Locking ISO low and exposing with shutter/aperture is why pro dusk shots look expensive.
