Photo Bracketing Sequence Namer
Batch-generate consistent filenames for exposure-bracketed photo sequences (e.g. -2EV/0EV/+2EV per shot) from a base name and bracket count, ready to apply during a HDR/panorama workflow.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.

Example shown — replace it with your own shoot's naming.
How it works
- Enter a base name for the shoot and how many bracketed sequences you captured.
- Choose how many exposures per bracket (3, 5, or 7) — the tool computes the EV offset labels for each.
- A full filename list is generated as
base_seq_EVlabel.ext, ready to copy or download for your rename workflow.
FAQ
What is exposure bracketing?
Exposure bracketing captures the same scene at several exposure values (EV) — usually one normal, one underexposed, one overexposed — so the frames can be merged into a single high dynamic range (HDR) image afterward.
Why not just use my camera's default sequential numbering?
Default camera numbering (like IMG_1042.CR3) doesn't tell you which sequence a frame belongs to or its EV offset, so sorting hundreds of bracketed shots by hand is error-prone. Naming each file with its sequence number and EV label makes batch HDR merging in post far less fiddly.
Can I use this list to actually rename files?
This tool generates the target filename list to use as a reference or to feed into your own batch-rename script or file manager's rename tool — it doesn't rename files on your device directly, since that would require file system access this browser-only tool doesn't have.
Naming helper vs. a dedicated batch renamer app

Use this to plan the naming scheme, then apply it with your file manager's or photo tool's own rename feature.
