Editing many photos at once

Copy values from one photo to others, set a field on a whole selection, fix a camera clock, add keywords in bulk.

All of these work on the photos you’ve selected (see Selecting photos) and appear in the bar at the bottom of the window while a selection exists. Every one can be undone right after with the toast’s Undo or ⌘ Z, and like any edit, nothing reaches your files until you save.

Drag a value onto other photos

The quickest way to copy one thing. In an open photo’s panel, drag any value by its ⠿ grip onto another photo. To copy it to many, select them first and drop on any selected photo: the drop target reads “Apply to 12 selected”. Drag a section’s ⠿ drag group to copy the whole section, for example every field of GPS & location.

Copy from a reference photo

For copying several sections at once from one photo onto a selection.

1. Select the photos to change, then click Copy from reference….
2. Click the photo to copy from. (Click Cancel in the banner to stop.)
3. Tick the sections to copy: date & time, camera & lens, exposure, GPS & location, copyright, title & caption, rating & label, keywords. Each shows the reference photo’s values.
4. Click Apply to … photos.

Set one field on many photos

Batch edit fields sets the same value for one field on every selected photo: lens, focal length, aperture, shutter, ISO, copyright, artist, latitude, longitude, title, caption, rating or color label. Pick the field, type the New value…, and apply. For copyright and artist, Use default: fills in the one from your Settings.

Fix a camera clock

When the camera’s clock was wrong (an hour off after a time-zone change, or never set for daylight saving), Shift timestamps… moves every selected photo’s capture time by the same amount.

1. Choose ← Shift back or Shift forward →.
2. Enter the days, hours and minutes.
3. Check the preview, which lists each photo’s old and new time, then click Shift … photos.

Keywords for a whole selection

Apply keyword set… adds every keyword in one of your keyword sets to the selected photos. Their existing keywords are kept. To create or change sets, see Keywords.

Your copyright on everything missing it

Checkup lists photos without copyright or a creator and, once you’ve set yours in Settings ▸ Metadata, offers to apply it to all of them in one click.
