How do I maintain the same exposure when changing one setting?

You can use the `calculate_exposure_shift` tool. By providing your current settings and specifying the desired change for one parameter, the tool calculates the necessary adjustments for the others to keep the total exposure constant.

Can this tool handle fractional stops?

Yes, the calculator supports fractional stop adjustments, including 1/3, 1/2, and 2/3 stops, for precise exposure control.

What happens if I request an impossible exposure setting?

If a requested setting violates physical constraints, such as a shutter speed faster than the flash sync speed or an aperture smaller than the lens allows, the tool will flag the combination as impossible.

This MCP server provides precise tools for managing the photographic exposure triangle. Use calculate_exposure_shift to find new settings when changing stops, evaluate_scene_brightness to determine the current Exposure Value (EV) and Light Value (LV), or calculate_metering_compensation to adjust for different metering modes. It handles fractional stops and flags impossible hardware constraints like flash sync limits.
