Lightroom export setup
I am creating a book and am looking for the best settings for files that are being sent to a printer. (blurb for example). I am importing raw files, usually 21 mgs in size, into Lightroom. After the files are processed I am using the export module in Lighroom to create a folder on my desktop. Those files are then added to the book creation program. I am looking for the recommending settings used for the image sizing section in the export module in Lightroom. Any suggestions.
