Photography Lesson #8 Telephoto Lens

A telephoto lens allows you to shoot objects from a distance. The longer the zoom the less light enters the camera. When using a telephoto lens, it’s ideal to have good lighting conditions.

If you shoot in a poorly lit environment you will need to compensate with a low shutter speed. A low shutter speed will make your images blurry if there is slight movement of the camera or if there’s movement of objects in the image. If you’re shooting a product shot then you can shoot using a tripod and a low shutter speed at a high zoom.

When using a telephoto lens there is no warp distortion of the image like when using a wide angle lens. The more you zoom the distortion is in the form of blurriness. Objects not in focus in front of and behind the main object will appear blurry. The more you zoom the more the blur effect will be apparent.

Depending on the zoom there will be a depth of field. As long as you remain in that field your images will be in focus. Knowing your depth of field range will allow you to have certain images blurred and others in focus.

Camera Lens F-Stop Values Explained

Lens aperture settings are commonly knows as f-stops. The letter "f" is an abbreviation of the term "focal-ratio", which describes the ratio of the lens's focal length to the diameter of the light entrance pupil (more commonly called the aperture). The standard sequence of f-stops is: f/1.4 f/2 f/2.8 f/4 f/5.6 f/8 f/11 f/16 f/22 On this scale, an f/1.4 setting is the largest aperture, while f/22 is the smallest, and each f-stop in the sequence is half the size of its neighbour to the left, and twice the size of its neighbour to the right. In other words, f/5.6 permits the passage of twice as much light as f/8, but only half the light of f/4. Low f-stop numbers represent larger apertures, and higher f-stop numbers indicate smaller apertures because the f-stop is a ratio is between the size of the aperture and the focal length of the lens; i.e. a bigger number represents a larger difference. Here's the maths for a 50mm lens. f-stop / Diameter (...

Automatically Update Your Facebook Page From Your Photo Blog

This video shows you step by step how to automatically create a post on your Facebook wall whenever you add a new post to your blog, without needing to do any extra work. This is a great way to keep people coming back to your website every time you add something new, espcially when you get to the stage where your Facebook page has hundreds, and even thousands of fans. One thing I forgot to mention in the video is that there are many app’s that will post your blog to a tab on your Facebook page, but this is virtually worthless. You see the only way people will come and check out your stuff is if it gets posted on their wall via your wall. And the best way to do this is to create a direct link between your blog and your Facebook wall using the method showed in this video, rather than using one of the Facebook app’s that simply creates a tab called ‘Blog’. For some people this may seem fairly advanced, but the reason I’ve included it is because it can be very powerful for yo...
