On a recent location scout, Anthony and I decided to have a little fun...
The technique used in the above image has been done by a lot of photographers so you're not really seeing anything new or unique. Even though, it is fun to do and it does build up skills both behind the camera (and in front) and in post processing.
Here's the principle; place your camera on a tripod overlooking an area you'd like to use as a backdrop. Meter for the ambient light and get your exposure set. Using your camera's timer mode, or have someone release the shutter, take a series of images of yourself in various places in the scene. Anthony did the honors for me for these images.
Once you have a nice collection of images it's time to load them up into your computer. You will need a good photo editing program for the rest. But before we get into the post stuff, I want to touch on a few basics about the shoot.

Second rule is to plan your shoot. Walk through your scene to determine where you're going to stand. Start off simple and chose locations where you won't 'block' yourself from one pose to another. Use your view finder to determine the field of view so you know how far left and right you can place yourself.

Keep photographic principles in mind. If your subject (you) is in shadow you will need to use flash for filler. This is where radio triggers are useful. Just make sure the flash is to one side and not between you and the camera. Don't worry if the flash is actually in frame as we are only concerned with getting a picture of you.

Be creative with your posing. Play around and have fun. As you gain experience you can do more elaborate compositions including interacting with yourself. You can even introduce elements of humor and storytelling with your compositions. You're only limited by your imagination.

I first open my base image in my photo editing program. If you took an unpopulated scene first you can use that as the base image. I use Corel PhotoPaint for my photo editing. Corel, Photo Shop and other higher end photo editors share a lot of the same tool structures so you'll be able to do this in any program that allows cut and paste and layers.

You will notice some discrepancies around the clipped edges. If your clones are near each other you will also see the overlap. Use your eraser tool with a feathered edge to erase some of the unneeded background around your clones. Pay attention to shadows. You don't want to inadvertently erase your shadow on a wall or floor as it will cheapen the effect. You'll also want to keep an eye on objects that have moved through your scene. You don't want two planes in the sky behind you. Go ahead and simply get rid of both of them.
Once you have fine tuned all the clones go ahead and flatten the image, do final touches on the scene and sit back and enjoy your work.
