What are Lightroom presets?
A Lightroom preset is a filter with predetermined settings and it can get you close to the desired effect quickly. It helps in post-processing or photo editing, saves time & energy, and most importantly it allows us to achieve certain looks that are hard to achieve.
Remember, a Lightroom preset isn’t a magic wand. Sometimes, it might nail it right out of the gate, and sometimes it might not. What it does though is very quickly get you close to the desired effect, and then you can tweak it to your vision.
