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.
- Grain (RMS)Grain The visible, sand-like texture in a photograph that comes from the clumps of silver or dye that form the image. Read more in the glossary ›
