It seemed easy enough. The client, a vitamin manufacturer, wanted a picture of one of their organic compounds, a bright blue powder. I thought making a small pile was going to be easy, but it turned out to be more challenging because it was extremely fine and also clumped and splattered easily when it rolled down the sides. So I had to invent some miniature spoon like tools and brushes to very carefully create and shape the mound. And if it splattered, I had to start anew because there was no way to clean the fine powder.
After a few attempts, holding my breath at times and an hour or two later, I had my miniature mountain but it was less than an inch high. This created other challenges like lighting to show the texture and to have the whole image in sharp focus.
A narrow grid spot light was moved around on top and to the back until I had good texture and shadow, and a second light was used as a general fill. The focus was another issue since even with the lens stepped down, only a small area was in focus. The solution was to shoot several images, each one focused on a different progressive spot covering the whole area from front to back. This final product is actually a composite of nine separate images assembled in Photoshop with a technique called photo stacking.
View or bellows cameras always had the ability to tilt the lens to an extent enabling better depth of field on a single shot. Since Photoshop has made it possible to achieve similar capabilities with standard digital cameras and lenses, I often use it as needed with better control and best of all – infinite focus depth.
