Best way to export images from LR for use in a photobook
« on: October 25, 2018, 10:26:09 am »

 My final selection consists of a combo. of TIFF, JPG, DNG & RAW images.(max file size 20 mp). For final conversion for use in photobook I'm making, JPG is being exported as JPG all others as 8-bit TIFF (16 bit tiffs are too large). Does this seem like a good process? Page size is 11.5 x 8".  Hoping to get max resolution and sharpness for the printed images.  Thanks

Not aware of any advantage to keep your jpg a jpg at export time. You are inherently imposing a second level of jpg compression on that export. My vote would be to export as 8 bit TIFF, appropriate ICC profile and resolution. Others may know about best jpg strategies.

Check with whoever is publishing your book.
If it's one of the plethora of photobook publishers they generally want JPG in sRGB. If that's the case I use the Lightroom export or print module to generate the JPGs.

If its a "real" publisher, then they have specifications for the files as well. My experience in that area has been that they will have a link to an ICC profile that should be assigned to TIFF files on export.
That's easily accomplished in Lightroom export module. Do it all the time.  For publishing with pre-press, I provide full sized 16bit TIFF files with ACES ICC profile. I've been told be several clients that that's a "standard default" ICC profile that the printers they use can change to the specific ICC profile for the print job at hand.

File size is never something I consider. It is what it is based on the final requirements.
