Lens types are classified as “Prime” which comes with fixed focal length and “Zoom” which has variable focal length.

  • Prime includes sub group of Standard (35- 80mm), Wide-Angle (15-28mm), Macro (50-100mm), Telephoto (80-300mm) and Super Telephoto lenses (200-400mm).
  • Zoom comes with variations like: Wide-Angle to Telephoto or Standard to Telephoto coverage. Even the point and shoot type of digital camera  comes with a Standard 35-80mm lens. A Standard lens is also known as “normal-lens” the term “normal” is used for this type because it captures a scene just as the human eye sees it. A Standard lens is great for everyday shots, such as flowers, people, or pets.

Wide-angle gives a broader view of a scene than a standard lens does. Because this lens captures a wide area it is used for photographing groups of people and landscapes.

Telephoto is used to enlarge pictures or for bringing distant subjects closer. A common telephoto comes with 75-300 mm coverage. When you begin to move from the 35mm into something larger it is best to either use a tripod or a stabilizer. A stabilizer will help you hold the camera steady for clear shots even if your hand moves a little bit.

Super telephoto comes with 200-400mm lens. It is mostly used for capturing wild life or birds.

A Macro lens is designed to capture a tiny subject as a bigger image. Macro photography is a type of shooting that magnifies
the size of a subject. As it name implies it is great for close up shots, such as flowers, spider webs, insects and other small objects.

Digital zoom simply crops the image to a smaller size, and then enlarges the cropped portion to fill the frame.

Optical zoom works just like a digital zoom. The lens changes focal length and increase magnification as it is zoomed.

Here is a design of all the components mentioned in the blog. This layout is for a website home page that I created while working at Comit Developers.

The elements of graphic design are used, and often combined, to create graphic works.

Presented here is a list of the most commonly used elements in graphic design.

Shapes
From ancient pictographs to modern logos, shapes are at the root of design. They are used to establish layouts, create patterns, and build countless elements on the page. With graphics software such as Adobe Photoshop and Adobe Illustrator, creating and manipulating shapes is easier than ever, giving designers the freedom to create them at will.

Lines
Lines are used to divide space, direct the eye, and create forms. At the most basic level, straight lines are found in layouts to separate content, such as in a magazine, newspaper, and website designs. This can of course go much further, with curved, dotted, and zigzaged lines used as the defining elements on a page and as the basis for illustrations and graphics. Often, lines will be implied, meaning other elements of design will follow the path of line, such as type on a curve.

Color
Color is an interesting element of graphic design because it can be applied to any other element, changing it dramatically. It can be used to make an image stand out, to show linked text on a website, and to evoke emotion.

Type
Type, of course, is all around us. In graphic design, the goal is to not to just place some text on a page, but rather to understand and use it effectively for communication. Choice of fonts (typefaces), size, alignment, color, and spacing all come into play. Type can be taken further by using it to create shapes and images.

Art, Illustration & Photography
A powerful image can make or break a design. Photographs, illustrations and artwork are used to tell stories, support ideas, and grab the audience’s attention, so the selection is important. Graphic designers can create this work on their own, commission an artist or photographer, or purchase it at all price levels on many websites.

Texture
Texture can refer to the actual surface of a design or to the visual appearance of a design. In the first case, the audience can actually feel the texture, making it unique from the other elements of design. Selection of paper and materials in package design can affect actual texture. In the second case, texture is implied through the style of design. Rich, layered graphics can create visual texture that mirrors actual texture.
