I'll be busy for a whole day event tomorrow, so I might as well share this now while I still have the chance to do so. ;)
Oh, about the background? Well, that's just a set of lights hung on a Christmas Tree (this shot was taken last Christmas Season). As for the way they look, I only slapped a cut-out of a heart shaped hole on a round cardboard in front of my lens, and the out-of-focus lights became just like that. A few tips to remember though: this method is best done using a prime lens, as the cardboard will block some of the front element, causing less light to enter the camera sensor. A Speedlight is also recommended to make your subject "pop" a bit. Also, you can try other shapes for your cardboard cutout, or you can even cut out an outline of your name. The possibilities are quite endless.
Happy shooting, and Happy Valentine's to all! :)
One of my little "habits" in covering events is that I would sometimes sneak up behind a photographer and take a photo of him/her taking a photo of a group of people, without him/her hardly noticing me at all. Another similar case is that I would take photos of people taking photos of themselves using their own DSLR or Point-and-Shoot cameras. Most of the time, they wouldn't really know that a "double exposure" was made until the photos are eventually shared to them by the clients via email, facebook, or the like.
I usually pull shots like this out of two simple reasons: 1.) a little story is made by capturing two interacting parties with their genuine expressions radiating in the photo, something that can be usually achieved if the photographer (in the photo) is someone dear and close to them, and 2.) if I need to take shots of interacting people, opportunities like this is one of the best ways for me to do so, without disturbing anyone in the process.
...which brings me to a little anecdote that I derived from a wedding that I attended, of which I came not as a photographer, but simply as a guest.
