Why Matt Black is Essential for Darkrooms

The Critical Role of Matt Black in Film Development

Matt black paint serves essential functions in darkrooms:

• Absorbs stray light: Prevents light contamination during film processing
• Eliminates reflections: No light bounce to fog film or paper
• Creates safe environment: Protects light-sensitive materials
• Professional standard: Traditional darkroom requirement
• Visual comfort: Reduces eye strain in safelight conditions
• Chemical safety: Dark surfaces show chemical spills clearly
• Traditional aesthetic: Classic darkroom appearance
• Complete light control: Essential for film and paper processing

Matt Black vs Other Darkroom Finishes

Matt black advantages:

• Maximum light absorption
• Zero reflections or glare
• Professional darkroom standard
• Protects film and paper from fogging
• Traditional darkroom appearance

Why not other colours:

• White reflects light (causes fogging)
• Grey creates unwanted reflections
• Coloured walls may affect colour perception
• Only matt black provides complete safety

Understanding Darkroom Requirements

What is a Darkroom?

A darkroom is a light-controlled space for:

• Developing black and white film
• Developing colour film
• Making photographic prints (enlargements)
• Processing light-sensitive materials
• Working with chemicals in controlled conditions

Light Control Requirements

Complete darkness needed for:

• Loading film onto developing reels
• Handling undeveloped film
• Loading photographic paper into enlarger
• Initial stages of print development

Safelight conditions:

• Red or amber safelights for black and white paper
• Specific safelights for different materials
• Matt black walls prevent safelight reflection
• Controlled, safe working environment
