Spectral sensitivity: Panchromatic — what this means

Sensitive to the whole visible spectrum, so colours turn into greys roughly the way the eye weighs them. This is what almost every general-purpose black and white film is. It has to be loaded and developed in complete darkness — no safelight is safe for it.

Notes on how this behaves in practice — what it does in the field is worth as much as what the datasheet says.
