Instead of using Lightroom to make my Photo books, I prefer to use Albelli, as there are more options and more possibilities.
I chose to use a wrap around Photo cover and Layflat Premium, as I have used this for all of my previous Photo Books and I want to keep this continuity throughout all of the books I produce, so they all have similar appearances. The Layflat is also a really good feature, as it allows you to make more out of the pages, as you can see properly the whole page, rather than the centre being less visible due to pages curving. I t also makes the pages much stronger, and makes the book feel a lot nice, in my experience, so even though it costs a lot more, it is well worth it.
