I have written about Matt Kloskowski's blog "Lightroom Killer Tips" in the past, but Matt has added a new wrinkle to his blog that I wanted to make sure you all knew about, it's called the "Monday Preset".
On (most) Mondays Matt shares with readers his personal presets, the ones he actually uses in his own workflow and there can be as many as five presets in the bundle. In the past they have included White Balance, Sharpening, and Split Tone just to name a few.
Here is a list of all the Monday Presets so far, but moving forward be sure to read Lightroom Killer Tips, especially on Mondays.
