A shutter measurement is only as good as the light behind it. ShuttR Lamp turns any spare iPhone or iPad into a steady, uniform white light source — the clean, controlled backdrop that ShuttR Check needs to read your analog camera's shutter speeds accurately. Ambient room light, dimmed bulbs and ordinary lamps flicker or shift in ways that quietly distort a measurement. A screen held at full brightness doesn't just shine brighter — it runs remarkably steady, which is exactly what a shutter test needs. ShuttR Lamp gives you that in one tap. HOW IT WORKS Open ShuttR Lamp on a second device, place it behind the camera you're testing, and point the lens at the screen. Then measure with ShuttR Check on your main phone. The lamp is the light; your other phone is the meter. An old iPad is ideal — a large, even, rock-steady panel — but any spare iPhone or iPad works. WHAT YOU GET A full-screen, pure white light at maximum brightness with one tap Brightness and warmth sliders when you want to fine-tune The screen stays awake — it won't dim or lock mid-measurement Tap anywhere to hide the controls, leaving a clean, uniform field of light A direct link to ShuttR Check when you're ready to measure FREE COMPANION TO SHUTTR CHECK ShuttR Lamp is made to pair with ShuttR Check, the app that measures your analog camera's real shutter speeds using just your iPhone.
