Handheld night frames without a tripod, using shutter, ISO, and stance instead of luck.
Low light is where most beginners give up, blaming their gear when the fix is usually technique. The first rule is shutter speed: to freeze a still subject handheld, keep your shutter at least one over the focal length, so 1/60s on a 50mm lens. If that lets in too little light, raise ISO before you slow the shutter further, because a slightly noisy sharp frame always beats a clean blurry one.
Stance matters more than people expect. Tuck your elbows against your ribs, exhale as you press the shutter, and lean on a wall or rest the camera on a railing whenever one is nearby. Enable your lens or in-body stabilization if you have it, switch to single-point autofocus so the camera locks exactly where you want, and shoot short bursts — the middle frame of three is often the sharpest. In truly dim scenes, focus on the brightest edge you can find, since autofocus needs contrast to lock.
