I have made many hand bound books using original photographs dry mounted on 240 gsm paper but there limitations.

Only light-weight (remember that?) photographic paper works well. Single weight is getting too thick and bulks the book up unevenly unless you have very few pages. To allow for the thickness of the photographs extra slips of paper have to bound into the spine of the book. Double weight photographic paper is too thick and I have never succeeded in making a passably elegant book using it.

A serious problem is that photographic paper is "stronger" than book paper. The pages buckle and bend at the mercy of the photographic paper and it's responses to changing humidity and temperature. A work-around is to dry mount exactly aligned same size photographs on opposite sides of the book paper. The photographs pull in opposite directions and things stay flat, sort of.

An ideal photographic paper for book-making would be an emulsion coated on tissue. A possible alternative is emulsion stripped RC paper. With RC it is possible to pull the image off the substrate by splitting a corner and peeling carefully.

With the disappearance of light-weight and single-weight photographic paper it is still possible to make nice books of original photographs but dry mounting does not come into it. The whole page has to be a sheet of photographic paper with the image floating in the middle. And the binding needs to be well crafted to deliver a book that does not break when opened and lies flat to best display the pictures.
