Although this or similar request were already posted by other users, I'd like to provide my own thoughts about wishful improvements of the book module of Lightroom CC.
I like the integrated RAW-workflow for creating a photo-book in Lightroom CC, which allows full flexibility until submission for printing when it comes to editing the images. But there is quite little flexibility, when it comes to the layout of a photo-book. I also appreciate the fact, that one does not need to separately store any JPEGs (I always export my files on purpose with appropriate settings, but do not store them).
In general, I don't need a whole lot of gimmicks that many other, even freeware, programs offer, but options, that are provided in
Ligthroom CC are a bit too restricted.
A more flexible and accurate control over position, size and aspect ratio of
images is terribly missed. It would be great to either have a greater variety of templates or, even better, have the possibility to freely set the page layout (without any restrictions referring to number, size and aspect ration of images on a single or a double page). It's quite annoying, when one has carefully set the frame to an image in post processing and than find out, that this has to be compromised when it comes to implement that photo into the book (either get a smaller version in the original aspect ratio or crop the image differently).
Also the options for the position of texts are quite restricted as no additional
text boxes can be applied (e.g. to apply a photo-text to a full frame image that is
shown on the previous or next page). Therefore, the possibility of being able to apply as many independent text boxes on a page would be highly appreciated.
Simple functions such as providing the opportunity to apply a thin border line around an image would be nice. The border layouts provided are not more than just nice to be used for one or the other Image, but certainly not for every picture in a whole book. In my point of view, such border lines are essential when it comes to overlapping images.
When it comes to the PDF-export of a book, it would be great, if every two pages (left and right) are printed on one page in a PDF-file. I'm aware that this can be fixed within a PDF-reader/editor, but that's not very convenient (additional work, double pages are broken up and a blank page has to be added to keep the left side of the book on the left in a 2 page view in the PDF-reader). By doing so, it would also be possible to automatically add the cover pages to that PDF-file.
Finally, the possibility to apply a background picture over a double page, would be highly appreciated (it works with foreground, why not with background?).
