what is a preset?

A Lightroom preset is a set of adjustments, designed to achieve a look or style for your photos. You install the presets in your lightroom app (see instructions) and then when you click on a particular preset while in the develop module, the default (preset) settings will be used to that photo. With just one click on a preset, your photo can be altered in hundreds of different preset modifications of colors, tints, shadows, contrast, grain, and more. The beauty of using presets is the consistency of style, time management, and simplicity they bring to your editing sessions. Finding presets that work with your style can speed up your workflow dramatically, and you can achieve the colors and look you want without having to edit each photo individually. Once you click on the preset and it is applied to your photo, you can make manual adjustments because the preset may not be perfect on every photo. Lightroom presets are a good base, but you can often still need to make multiple adjustments to each photo to make sure they're perfect.
