I mean every spread. It's your call, but I prefer white pages in my albums. I find them to be more timeless and less distracting. But again, this is your call. Being that your couple is a little non-trad, I'd ask them if they prefer black or white if you're okay with either.
i get the feeling that they are TRULY happy from looking at their photos.
i think the photos overall are very nice, however, i think a different presentation would make it stronger. for example, in 17, i'd like to see the main photo and the lower right photo as individuals. i think displaying them as a set weakens all of them. same for the last one. the portrait is strong, the two on the right are not. just show the main one. same with #9...right image really good, left, eh.
just messin!
