Presets versus filters: what is the difference
Many beginning photographers use the terms preset and filter interchangeably. They are, however, fundamentally different things, and the distinction matters if you want to improve your editing skills.
A filter, as you know from Instagram or VSCO, is a destructive edit applied directly to the pixels of a JPEG photo. You cannot undo it without the original photo. Quality decreases with every editing step.
A Lightroom preset is non-destructive. The original RAW or JPEG photo remains unchanged. Lightroom stores the editing instructions as a separate layer and applies them during rendering. You can reset everything to zero or adjust further at any time.
The second major difference: presets work across all Lightroom editing parameters simultaneously. Exposure, contrast, colour tints, HSL channels, sharpening, grain, lens corrections. A filter typically does only one or two of those things.
In short: if you are serious about photography and work with RAW files, presets are the tool. Filters are for quick sharing on social media.
