光尺 - 胶片测光测距仪暗光测光

The Light Ruler is a "dark-light buster" and "range-finding magic tool" designed specifically for film photographers. We have combined a professional light meter and a precision laser rangefinder into one, aiming to solve the shooting problems of rangefinder and zone-focus cameras in complex environments. Whether it's low-light night scenes or fast抓拍, the Light Ruler can help you take precise photos.

【Core Functions】

The first dark-light metering engine breaks through the limits of traditional mobile phone metering and is tuned specifically for low-light environments. It can still provide accurate exposure readings in extremely dark environments, ensuring that your night-scene films are not underexposed.

LiDAR laser precise range finding Utilizes Apple LiDAR laser radar technology to achieve real-time range finding with centimeter-level accuracy. Completely bid farewell to the embarrassing situations of "blurred vision due to macular aging" and "focusing solely by feeling", making every shutter sharp and clear.

Intelligent reciprocity law compensation Built-in database of mainstream film reciprocity laws. There is no need to look up tables or do mental calculations. Just select the film type, and the App will automatically calculate the compensation time required for long exposures.

【Solving Pain Points】

Saving wasted films: Solve the problem of dead black caused by inaccurate metering in night-scene shooting.

Liberating the brain: Bid farewell to the cumbersome reciprocity law calculation formulas and the paper forms carried around.

Revitalizing old cameras: Even old cameras with malfunctioning macular focusing can obtain a modern focusing experience through the "Light Ruler".

【Target Users】

Film/analog photography enthusiasts

Users of rangefinder cameras (such as Leica M series) and zone-focus cameras (such as Rollei 35)

Photographers keen on urban night scenes and long-exposure creations
