WIP Francisco Palacios

This is a logo I'm currently working on. It seems finished to me but the client want me to add something to the mark that represents palaces (like his surname) or photography. But I'm not pretty sure what to do to represent film or photo adding something to the actual shape.

Here's a variation that I made but doesn't achieve what I'm looking for

Please help me to enhance this concept :D
