A second light source — usually called a fill light or fill flash — can greatly improve portrait lighting. It reduces the depth of shadows and softens the appearance of facial features, amongst other traits. Best of all, a fill light is easy to create: either a simple on-camera flash or a reflector is often sufficient. However, a second light source can just as easily harm portraits. This tutorial therefore focuses on how to control the location and intensity of the fill light in order to produce a desired portrait appearance.
by Matthew Cole Photographers set their exposure using a combination of shutter speeds and f/stops to get the correct amount of light on the film/sensor. The shutter speed regulates how long the film is exposed to light coming through the lens. The f/stop regulates how much light is allowed through the lens by varying the area of the hole the light comes through. For any given film speed (ISO) and lighting combination there is one correct amount of light to properly expose the film. This amount of light can be achieved with many different combinations of f/stops and shutter speeds.
Bernie’s Better Guide to Depth of Field for Geeks Who Want to be Digital Artists | Bernie Sumption :: PhotographyBeing a guide to portrait photography cleverly masquerading as a technical analysis Like the topics we covered in the beginner's guide last month, depth of field might initially seem complex, but behind it is some relatively simple logic and maths. Don't worry if maths isn't your strong point: long equations are the crutch of the inarticulate, and there's nothing in this article more complicated than division. Speaking of division, I like to divide photography into two broad disciplines. Portraits are photos of a particular object (not necessarily a person), designed to capture something about that object.
What do all the numbers and letters on a digital camera lens refer to and what do they mean? If your new to DSLR photography the first things you'll need to know when buying a new lens will be concerning the numbers and letters printed on the lens. You will need to know what they mean to ensure you buy the lens that suits your specific needs. First I'll start explaining what the mm number means. For example on a Canon EF-S 17-85mm f/4-5.6 lens you will see the number 17-85mm written on the side. The mm number refers to the focal length.
