Pro tips voor helderheid & contrast
Adjust Brightness First
Get the overall exposure right, then fine-tune contrast for the finishing touch.
Don't Over-Adjust
Subtle changes (±20-30) often look more natural than extreme adjustments.
Watch the Histogram
Avoid clipping (pure white/black areas). Keep detail in highlights and shadows.
Consider the Subject
Portraits need less contrast than landscapes. Match adjustment to content.
