What changes
Light quality depends on the physical size of the acting source: larger or more diffused sources produce softer light.
HARD-VS-SOFT-LIGHT · foundation
Hard vs soft light
Hard light produces a sharp, defined shadow edge; soft light produces a broader, less defined edge.
On-set method
- Observe the edge of a cast shadow.
- Compare a small direct source with a larger diffused or bounced source.
- Keep exposure comparable so edge quality can be judged separately from brightness.
Useful for
- Hard light for defined shadows and visible texture
- Soft light for broad transitions and a more flattering treatment of facial lines
Common mistakes
- Equating soft light with low intensity
- Expecting a small, undiffused source to create a broad soft shadow edge
05
Practice
Photograph one object under a small direct source and then under a larger diffused source at comparable exposure.
06
Compare
Hard and soft describe shadow-edge quality; high and low key describe the broader distribution of illumination and shadow.
FAQ
Does brightness determine whether light is hard or soft?
No. The ARRI handbook states that light quality is determined by physical source size rather than intensity.
