Technical product photography is not something I do very often, but I really enjoy the challenge. Quite different from photographing events, or even property, the photographer controls everything when it comes to product photography.
Firstly the background. For most product photography a white background is preferable, as the products need to be shown clearly on websites, and advertising material. Secondly, the lighting. Multiple lights are often used, to create an evenly lit, clear image, that shows all the necessary detail that a potential client needs. Next comes the camera equipment. I use a high resolution Nikon mirrorless camera, with a macro lens fitted. And finally the photographer – me. And I make it all happen.
A very important technique I often use on product photography is called focus stacking. Focus stacking is a technique designed to achieve a deep depth of field by blending (or stacking) several images together. Each stacked shot is focused in a different spot, so the combined depth of field is deeper than the depth of field produced by any of the individual images. In simple terms, if I focus on the nearest point of the product I am photographing, it doesn’t matter how small an aperture I use, the furthest point of the product will not be pin sharp (and quite often is out of focus completely). I can set the camera to take a set number of images, at variables of my choosing, to capture the product at various focus points. I might end up with anything from six to twenty images, which I then combine in post processing to create one final image, where everything is sharp.
These are examples of a recent photoshoot for Partech Instruments, where I used these techniques.
