PEEPER on Instagram: "Shutter speed is one of the core principles of photography, controlling how long the camera’s shutter stays open to let light hit the sensor. Measured in fractions of a second—like 1/1000, 1/500, or 1/30—it determines not just exposure, but how motion is captured in an image. With a single adjustment, a scene can shift from perfectly frozen to beautifully blurred. A fast shutter speed, such as 1/1000, opens and closes so quickly that even fast-moving subjects appear sharp.

PEEPER on Instagram: "Avalanche control is a critical safety practice in mountain regions, where heavy snowfall can make slopes unstable without warning. By triggering small, controlled slides before conditions worsen, operators reduce the risk of large, destructive avalanches that might otherwise release naturally during storms or sudden temperature changes. One of the most effective methods uses artillery to deliver explosive force precisely onto known avalanche paths. This allows teams to rel
