Pro tips voor grijswaardenconversie
Choose the Right Algorithm
Luminosity works best for photos. Average is faster for batch processing. Experiment to see differences.
Increase Contrast Slightly
Grayscale images often benefit from 10-20% contrast boost to maintain visual punch.
Consider the Subject
High contrast B&W suits dramatic subjects. Soft grayscale better for gentle, romantic images.
Keep Original Files
