Most of us know that a picture can tell thousands of words. But which words the picture will tell is dependent upon many things. The most two important elements of a photograph are composition, and lighting. To tell the story for our purpose, rightly, ideal arrangement of people and objects are extremely crucial. Suppose, you will need an image of Niagara falls to your next advertising campaign for a particular product.
You ship your best photographer to take the right photos, but the model of the product couldn't turn up there for her program issue. The simplest solution for this specific problem is to take the picture of this model later in the studio and set her figure on the Niagara Falls photograph. We can even add the picture of the item or any other essential objects, texts, effects/special effects, blah, blah, blah... afterwards, using image manipulation and graphic design applications.
