POVray, Yafaray and Luxrender are example of free 3D rendering engines. However, there are free rendering programs as well. Most rendering software program are commercial in nature. One popular program known as Keyshot is build like a photo studio. Many 3D programs can create photo real images. In this current age and technology, 3D modeling and rendering technology have replaced product photography in some cases. The diagram below shows a typical Product Photography setup. To prevent shake that may result in blurry images, a tripod is often used. If a digital camera is being used, the simplest way to address this issue is to set White Balance setting to auto. Because the product is often shot under these artificial lighting conditions, the White Balance factor must be considered and be compensated accordingly. For instance, Florescent lamps will produce a green cast over the image. This is often in the form of a background table or lightbox.Īrtificial lighting conditions produces color casting effect over the photos. However, if a shadow-less white background is desired, back-lighting has to be used. The main light may be in the form of overhead or frontal light. One will usually be the main light, while the other serve as a fill light to prevent dark shadows. To bring out the details of the product, often the setup will involve at least 2 light sources. This backdrop lies flat but arches upwards towards the background. To achieve this effect, a dark-coloured or white drape is often used as a backdrop. This is done so as not to distract from the main focus which is the product itself. Often, the background is purposefully rendered as a monotone color. Most products are shot within an indoor studio setup. It is also known as Commercial Photography. It is often used in Product Advertisements. Product Photography is the depiction of product design in an appealing manner.
