1. Can I do something with my pdf desktop files to make my book in Blurb?
1. No. The PDF is what it is! and cannot be used in Lightroom. At best you may be able to create 'Snapshots' in a PDF reader and use those images in a 'new' book.
2. Will the resolution be the same as my original in Lightroom?
2. No. That will depend on the resolution of the PDF and the size of the PDF image on your screen.
If you have backup copies of your photos that Lightroom can access then- yes, you will be able to re-construct the book in Lightroom. You do have backup copies on another drive? yes?
I have just tried the exercise using a Book pdf viewed in Foxit Reader (Full screen, enlarged size), Alt+7 copies a page to clipboard, paste image to Photoshop. The image looks quite acceptable on screen. With some further editing it may re-construct OK.
I ended up just going to Blurb and using their upload pdf, put my pages pdf
and cover pdf in their upload boxes and after a bit, all had uploaded.
Since it took a while I am hopeful that the resolution is high. These
pdf's were created within the Lightroom book module where it says save to
pdf. I haven't yet received the book, so I don't know if there is any
problem. Thanks for help offered.
Sounds like you did the right thing, and your book will be great!
The PDF from Lr will have the necessary quality suitable for the book you designed.
Uploading the PDF to Blurb, external to Lightroom, did not occur to me to mention in my previous post. (brain lapse)
OTOH if you have lost all the original images that cannot be recovered, then the PDF is going to be the only source to recover the photos.
Of interest- my PDF for a 10x8in book with single image pages- shows the images very well for a screen-clip exercise on my 27inch monitor.
Thanks so much for your thoughtful and timely responses... I haven't used
these forums before, and I am new to Lightroom, and am a bit elderly... but
I try to push through. Indeed, I had no other back up for my pics than the
external hard drive that failed (me). I am now moved to try Dropbox, ....
clearly I need to do double back ups.... ugh!
