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.

Reciprocity
| Metered | Expose |
|---|---|
| 1 s | 1 s |
| 2 s | 2.4 s |
| 5 s | 7.6 s |
| 10 s | 18 s |
| 30 s | 1 min 13 s |

Tc = Tm^P for metered times over 1 s; 1 s or less needs no correction (P = 1.26)
