Select one or more photos and choose File ▸ Export… (⇧⌘E). The export dialog is organised into sections:
Export Location — the destination folder, and an optional subfolder.
File Naming — rename the exported files with a template.
File Settings — Format (JPEG, TIFF and more), Quality, Colour Space and Bit Depth.
Image Sizing — resize to fit a target dimension, or export at full size.
Output Sharpening — sharpening tuned for the output.
Metadata — how much metadata to include.
Watermarking — apply a watermark (create them in Lumidex Studio ▸ Edit Watermarks…).
Post-Processing — what happens after export (for example, show the files in Finder).
Export again, instantly
File ▸ Export with Previous (⌥⇧⌘E) re-runs your last export with identical settings and no dialog — handy for batches you export the same way every time.
Note: video export isn't supported in this version.
