What is A Digital Back Drop?
The purpose of digital back drops is rather simple - to replace original background of a digital image (it can be photo or snapshot) with another alternative background. A digital back drop is such alternative. In other words, a digital back drop is an images that can be used as background image in digital photography instead of original background of photos, images or snapshots.
Why someone would need to replace original background with different background? Well, there can be a lot of reasons. For instance, one wants to turn an ordinary snapshot into a classical studio photo portrait. Another reason of using digital back drops can be pure technical - to replace distracting background with un-wanted "aliens" by a more graceful background. In any case, the usage of digital backdrops inspires limitless inspiration and supports technical needs for a very low cost.
