Creative Photo Techniques (and Creative Photography Tips)
It's time to work more on your creative photo techniques, once you've gotten a basic understanding of lighting, composition and exposure. I've written a series of articles on creative photography tips so that you might be inspired to get creative with your photography. One of the first creative photo techniques I had a lot of fun with when I was just beginning to experiment was multi-exposure. Of course, it was tricky back then because I was working with film and darkroom techniques.
No, these three dogs are not identical triplets. This photograph was created from the three separate photos of the same dog shown below. It is actually often a simple digital photo editing trick than can be done easily once you learn it and have planned ahead.
To accomplish this effect, you must use a tripod to hold the camera in the exact same spot for every exposure. This will insure that you can combine the photos with no loss in quality or sharpness when you do your photo editing. In the case of the multiple exposure of the German Shorthaired Pointer, I also needed a couple of dog biscuits to bribe her to stay in each of the locations for the three photos. You must also use a shutter release or the camera's self-timer to keep your images sharp unless you are using a high shutter speed or flash lighting to avoid camera shake. I use Adobe Photoshop, but you can also use Gimp, which is similar in capabilities and it's free software. There is also a multi-exposure feature within the "Make a Collage" function of Picasa, but you will get the "ghost" effect when you combine the images. Essentially you combine your different photos into one by stacking them as layers. You can they reveal or hide any part of any of the layers independently by making them into masks. When you are completely satisfied with you editing, you can "flatten" your layers into one single photograph. 
I planned the 3-dog photograph so that there was plenty of room in between the three spots the dog would occupy in each of the separate photos. Another one of those creative photo techniques is really just some creative photo editing that I frequently use with nature photography. Again it is done with Adobe Photoshop. Look at the dramatic difference in the two photos below taken in Zion National Park. The photo on the right was adjusted using curves. This is an advanced technique used to control contrast. The photo on the right was also sharpened a bit using Unsharp Mask applied to the "lightness" channel only in LAB mode. It's a very advanced technique that I use frequently and absolutely love the results I get.
It takes a bit of experimenting to get to your desired result, but my adjustments to the curves often resemble a lazy "S" shape. This shape increases contrast in the shadow areas and the highlight areas, but has little effect on the mid-tones.
