Color Profile: You can choose a color profile for your exported album spreads. (sRGB, Adobe RGB, Match Images).
Export File Names: You can toggle this on to export your spreads with the filenames showing for each image in your spreads. This can be useful for proof books and client previews of your album.
Once you've selected your options, click the Export button to being the export process.
Once you click the Export button, your export will begin. A progress bar will display showing you the export progress.
