Why this one
What makes it different
Strength you control
Sepia at full strength is a costume. At twenty percent it is just a warm cast, and that is the setting people actually want more often.
Tonal detail is preserved
The brightness relationships stay intact underneath the tone, so the image does not go flat the way a colour overlay makes it.
One pass, no stacking
A single tone applied cleanly rather than desaturate-then-tint, which is where the muddy version of this effect comes from.

The short version
About sepia
Sepia is a real photographic process before it was a filter: toning a silver print to make it last longer, which is why surviving nineteenth century photographs are brown. That history is why it signals age so reliably, and also why it looks like a costume at full strength. Most of its modern usefulness lives in the first quarter of the slider.
Questions
Sepia FAQ
What is sepia, actually?
A warm brown monochrome. It comes from a real photographic process that converted silver in a print to a more stable compound, which is also why genuinely old photographs are brown rather than grey.
How strong should sepia be?
For a nostalgic hint, fifteen to thirty percent. Full strength reads as a deliberate period effect, which is fine when that is the intent and heavy-handed when it is not.
Is sepia the same as a warm filter?
No. A warm filter keeps the colours and shifts them warmer. Sepia removes the colour entirely and replaces it with a single brown tone.
Can I undo sepia later?
Not from the saved file. Like any tone, it replaces the original colour information, so keep the original if you might want it.
