photo.sensor-noise-iso Calculator
Estimates the signal-to-noise ratio penalty from raising ISO above a camera's base ISO, and shows the effective dynamic range remaining at each ISO setting. Each stop of ISO increase roughly doubles noise — this quantifies the trade-off before making exposure decisions.
Inputs
Base Iso
Reference formula or conversion factor shown for context.
Current Iso
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Bit Depth
Vertical extent downward, or thickness of a layer. For tanks: affects pressure at the base (P = ρgh).
Dynamic Range Stops
Reference formula or conversion factor shown for context.
Results
effective dynamic range at ISO
The difference between the maximum and minimum values.
noise increase vs base
Random or irrelevant variation in the measurement.
full-well capacity approx
Reference formula or conversion factor shown for context.
ISO multiplier
Gratuity amount — the suggested amount to add to the bill as a service tip.
rule of thumb
A widely used practical approximation or heuristic for this field — useful for quick estimates but not a substitute for rigorous calculation.
