Even with four flashes, I've run across situations where five, or six, or even eight flashes would have been desirable. I usually end up having to make due with what I have and the results sometimes fall a bit short. That got me to thinking about how I might be able to more effectively use the four units. After some thought and watching a few videos, it finally dawned on me that under certain situations, I could easily turn those four units into eight. It's all a matter of combining several images into one to obtain the desired results. Let's take a look at how this works.
Under normal shooting situations you would probably not have the time nor the need to follow this process and this is not HDR (Hi Def Res). To use this process you must be trying to accomplish a single task, or put another way, to come up with a single photograph and not try to capture a lot of different images. The idea then is to think out ahead of time what kind of image you are wanting capture, and then plan your shoot in such a way as to have a good idea of what you want the finished photo to look like. It takes a bit of planning and pre-knowledge of how speedlights work and some PhotoShop skills come into play as well, but they are relatively straight forward.
Let's look at how this photo was accomplished. It is a photo taken of a pilot and his airplanes at sundown. The nature of the natural light dictated that several speedlights would be required to get the desired results. What I wanted to do was to have his two airplanes sitting in the hanger with a Kentucky sunset in the background. I also wanted the pilot to be up front and center...it's really a portrait of the pilot, with the airplanes in a supporting role. The background and general setting was used to simply establish a point of reference and add interest.
There were several planes of light used in this shot, each with a different required exposure value. The first plane of light was the background sunset with the pilot in the foreground. The second plane was just the background and a third plane was the hanger with the airplanes inside. I did add a 4th plane, but it was a simple lighting of the fuel container standing next to the hanger.
So the basic process was this; I took several photo's of the sunset and pilot using two strip lights so as to provide light along the full length of the model. The exposure was set for the background, and the striplights were added to fill in the light on the pilot. This image then became the base line image, the one upon which the others would be built. Once I had the sunset composition established, the camera was then locked down and was not to be move again during the shoot. Focus and exposure values were set to manual and would not be changed during the rest of the shooting.
With the hanger composed against the background, the inside of the hanger became very dark. As a result the hanger and airplanes inside were not visible. What was required was to provide some illumination to the inside of the hanger, and to the airplanes themselves. To setup the second plane of light, I set three speedlights low inside the back of the hanger. On two of the lights were orange and yellow gels which were added to provide a bit of color to the back of the hanger and to also tie it in with the sunset. One light was left bare, mostly to provide some simple fill light. I took several shots with this configuration. Of course by this time the sky had become darker, but that was okay...you'll see why later.
As an added note I ran into trouble while performing this setup and exposure. The lights were a good distance away from the transmitter sitting on my camera which resulted in a weak signal on the receiver end causing the lights to not fire like they should have. Sometimes one woudl fire, but the other two would not. What I ended up doing was setting two of the lights to Slave Mode, and allowed the one light that was firing to trigger the other two with its flash. I also had to move them closer to the front of the hanger...those few yards seemed to help. This effectively solved my firing problem, however we lost a lot of time and experimenting opportunities because of the delay.
Once I had a satisfactory image of inside the hanger and airplanes, I captured a simple shot using one flash pointing at the fuel tank alongside the hanger.
Once I had all of these photo's taken, the next step was to blend them all into a single photo. This was done using PhotoShop Elements. First of all I had to create a base image by combining the two sunset images into one. This allowed me to erase the strip lights out of the image and to expose the background image behind them thus giving me a single image of the sky and the pilot without the lights showing.
I then opened the hanger picture and tweaked it slightly to bring out the details I wanted. This sky background photo was them copied and pasted onto this hanger photo. Using the eraser tool, I began to remove the the darkened out hanger exposing the lighted airplanes that resided on the layer underneath. Once I had accomplished this, I flattened the image to merge it into a new single image.
Then I opened the last plane of light and tweaked it much the same way as the previous one bringing the fuel tank into view. Finally after some overall tweaking I flattened the entire image and saved it.
Overall I was pleased with the results...I feel I can do a better job as this particular image still needs some work, and maybe someday if our pilot wants to give it a try, we'll do another session. The delay caused by the malfunctioning trigger cost me too much in being able to really do all the more subtle photographic techniques I wanted to try...in reality I became frustrated and failed to focus on the things I should have. Regardless, we had a good time, I learned something new, and ended up with a pretty good photo.
