Creative use of Depth of Field (DoF)

Control of depth-of-field is one of the most creative tools photographers and DSLRs have.  
But what exactly is depth-of-field?
In the most basic terms, it's the distance in front of and beyond the subject that appears to be in focus.


Choose your subject—that rose flower in your garden, for example—and focus on it. Depending on what you decide now, you can make the grass in front of that bush sharp or soft; likewise, the fence behind the bush.
Choose to let the foreground and background go soft and you've effectively isolated your subject and called specific attention to it. Choose to have the foreground and background sharp, and the rose bush becomes an element in the overall scene.
The key to using depth-of-field to isolate or blend your subject is lens aperture. Wide apertures, such as f/2.8 or f/3.5, provide shallow depth-of-field: your subject is sharp, but little else is.

Narrow apertures, like f/16 or f/22, provide a much greater depth-of-field, so that the territory in front of and behind the subject will be in focus. I haven't shot anything like that yet but, I have shot enough landscapes where you want to get everything in focus.

Simply, the smaller the number, the shallower the depth-of-field; the greater the number, the greater the depth-of-field.

Long Exposure Photography

One of the areas of photography that people get wrong is night photography, most people assume that you just use the flash and everything is fine. OK, this is fine for the odd snap shot of your friends or on a night out. But, if you want to get creative and make stunning images at night you’re going to have to do a lot more than just turn the flash on, when you have finished reading this you’ll be able to create images like this:

In this article I am going to show you how to use a technique called Long Exposure. Say good bye to harsh lighting and dark backgrounds. Sort of. This article will show you how to take pictures of night scenes with no moving objects. Night photos of people I will show you later on in another article as that is another kettle of fish.

Firstly, let’s pick a subject. For this article our subject will be a lake. That is easy, it doesn’t get too much more difficult. I promise. Now you have your subject, you’ll need to get your equipment setup. For this article, I’ll use my equipment to show you what is needed.
