I think a general tutorial would be much more helpful than “just” templates, since the page sizes are so different for the different services. However, probably scribus allows a more generalized way of templating that adapts to the actual sizes, I am unfortunately not that deep into scribus.
What I can offer is a lot of questions concerning such a project, where I stumbled over particular issues that hindered me during my tries of starting a photo book. Some of them are:
- Sorting the photos: Using darktable, what I really miss is doing sorted collection as preparations for photo books. Of course I can add all images that may be used in the project into one collection by adding a tag, but there is no possibility to bring them into an arrangement that reflects their order in the book.
- Building reasonable page templates and working efficiently with them, especially with images and text.
- Aligning images into the template layout, especially if the box is fix and you want to shift your image around to see the best crop (as told before, this already improved a lot).
- Vertical text alignment. While this was implemented in scribus, I have no idea which version I have to install to get the feature, all that seem to be available precompiled for ubuntu seem to lack this feature.
- Export: How to maintain the book for print including bleed and have an PDF export without bleed?
- Double-side spreads: In principle, these are simple in scribus, but for “lay-flat” photo books with, e.g., saal (a German supplier) an odd number of horizontal pixels is required if you want to upload image files instead of the PDF. That was driving me crazy (not a particular problem, but probably there’s a solution out there).
Furthermore, there’s another problem. Not being a designer, I have to learn a lot to do a reasonable font choice, typography, layout (I prefer classical layouts which are focused on the pictures and text and avoid colourful clipart), … Probably such a tutorial has to kickstart these points as well to result in beautiful photo books. (For a good kickstart into general typography I can recommend http://bit.ly/typokurz-cb from https://zvisionwelt.wordpress.com/downloads/, at least for the German speaking folks)
