Free Lightroom Presets

Underexposed: Gently increases the brightness and exposure
Fancy Snapshot: Adjusts exposure, colors, contrast, and slight sharpening. Great for quick proofing.
Sing: Really amps up the colors, especially outdoor shots. One of my favorites!
Golden Girl: Great for backlit shots
Blue Eyes: May need some exposure adjustments but will enhance blue eyes.
Tres Cool: Edgy colors and a strong vignette
Edgy Vintage: Similar to Tres Cool but with more muted colors.
Modern Vintage: LOVE this one. Muted, but not simply desaturated.
Soft BW: Another one of my favorites.
Mocha: Slightly toned BW conversion.
Moody: High contrast and deep blacks
Silvery-toned: High contrast and very deep blacks. This may require some exposure adjustments.
Copper: Toned BW.
