Ben:
Here's what E.E. O'Donnell says in "The Last Days of the Titanic," (page 65) which is a collection of all the Father Browne photos:
"Stepping forward a few feet, and turning to the left (from the double doors leading into the starboard Verandah and Palm Court), Frank Browne has encountered an unidentified couple taking an early stroll. The port cargo crane is much more visible here than than the starboard one was in the previous photograph (page 77 bottom of the Marriott book and page 64 of the O'Donnell book). Overhead, deck-chairs are stacked against the railing of the second class promenade. The absence of clearly defined shadows shows that it was overcast this morning. An unusual facet of this photograph is that it is a double exposure. Barely visible is the wicker furniture of the starboard private promenade, part of a suite occupied by Mrs. Charlotte Drake Martinez Cardeza, a Philadelphia millionairess and big game hunter who had boarded at Cherbourg the previous evening. Flowers, possibly wishing her bon voyage, grace one of the tables. The door leading from this promenade into the first-class enterance-way must have been open for Frank Browne to have this image as he surely did not know Mrs. Cardeza."
An earlier part of the O'Donnell book shows the same pictures as they appeared in Father Browne's album. The only caption below the picture you mentioned says 'First Class'. The other picture I mentioned says 'Second Class'.
This probably doesn't help you much, but the double exposure note is interesting.
