LUT stands for LookUp Table. It’s a digital file that shifts colors and tones in hue, saturation, luminance – usually all three. LUTs are used widely in video editing and cinematography, but are becoming increasingly popular in regular stills photography. They are like ‘pre-processing’ for images. They give you a whole new look without involving any of the editing tools – unlike presets.
Verdict: 5 stars Lutify.me is a subscription-based LUTs package for both video and stills, which includes excellent downloadable LUTs and an online LUT previewer.
