Exposure Lab
The ultimate exposure workstation. Calculate the perfect balance between Shutter Speed, Aperture, and ISO while accounting for external filters and film physics.
Exposure Triangle Solver
Define your target. Insert two parameters (e.g., Aperture and ISO) and let the Lab calculate the third one. Perfect for shifting settings while maintaining the same Exposure Value (EV).
ND Filter Integration
Calculate long exposures with ease. Input your base reading and select your ND filter (from 0.3 to 20 stops). The Lab instantly computes the final required shutter speed or adjusted aperture.
Manual EV Compensation
Fine-tune your exposure for specific creative needs. Apply positive or negative EV compensation to your calculations to account for high-contrast scenes or specific sensor behaviors.
Reciprocity Failure Engine
Analog film doesn’t react linearly to light in long exposures. Select your specific film stock (Kodak, Ilford, Fuji, etc.) and the Lab automatically compensates for reciprocity failure using precise mathematical curves.
“Reciprocity Only” Mode
The fastest way to adjust your shot. Input your metered shutter speed and instantly get the real, corrected time you need to set on your camera, bypassing secondary adjustments.
Cumulative Calculations
The professional analog path: Combine your base reading + ND Filters + EV Compensation + Reciprocity Failure. The Lab stacks all factors to give you the one definitive exposure time.
