Today, on the JBS Mercantile Inspiration blog, I wrote about using the things kids says to help guide both your product choices and the creation of your title. You can literally jot down something your child says to you and use that as a title. You can also use symbols to make a more interesting title.
Look for items that can be substituted for words within the title. These symbols make the title more interesting. Playing around with the symbols will likely cause you to come up with a more interesting title than just using the photos alone. This title is much more exciting than something like Neon Vampire Teeth.
Explore both symbolism and voice when considering what you want to use for a title. Look at the actions of the people in the photograph to determine what symbols might work for your title. If you didn't jot down something your subject said, chances are that you know them well enough to think of a phrase they may well have used.
