In Parts 1/2/3 in the prior issues, many aspects of making a technically optimal image were covered. This final part four wraps it up with the last major key concept: optimal exposure.
Optimal exposure extends dynamic range, minimizes noise, improves color
Optimal exposure results in the highest possible “signal to noise” (S/N) ratio. By making an optimal exposure:
- Maximum dynamic range (usable range of dark to light) is achieved.
- Noise is minimized, which means greater dynamic range.
- Color quality in dark areas improves substantially (polluting effects of chroma noise are minimized).
