Bokeh Basics: Take and Make Great Photography with Gavin Hoey

There are now a variety of ways that you can take digital photography classes to help you learn how to use your camera. Whether you are just the occasional photographer and like to take snapshots on vacation, or you plan on using your new camera for some serious photography, you should take the time to enroll in digital photography classes to make sure that you actually know what you are doing. You may be surprised at what your camera can actually do for you!

It is not necessary for colour images to be strongly coloured in order to have impact. You can, for example, use desaturated hues – those that contain more grey than actual colour – to make more subtle colour statements.

Many people have been taking pictures with a digital camera for years, but whether you are new to the world of digital photography or an expert, you can benefit from the valuable tips and insight available to you in a digital photography guide. With all of the insight and pointers inside your guide, you can learn how to take amazing photos.

Interactions between layers are tricky to learn, as their precise effect depends on the value of a pixel on the source, or upper, layer compared with the corresponding pixel on the destination, or lower, layer. The most often-used method is simply to try them out one by one (hold the shift key down and press “+” or “?” to step through the menu) until the effect looks attractive.

The “layers” metaphor is fundamental to many software applications, such as desktop publishing, video animation, and digital photography. The idea is that images are “laid” on top of each other, though the order is interchangeable. Think of layers as a stack of acetate sheets with images; where the layer is transparent, you see through to the one below.

A gum dichromate is a flat colourization of a grayscale image; in the process, however, the tonal range tends to become compressed. Gum dichromates have had a popular following for most of the history of photography – they are relatively inexpensive and tolerant of processing variations, they are an accessible way to add colour to black and white images, and the technique is a rapid route to effects that look painterly.

There are two ways of limiting the action of an image-manipulation effect: using a tool that applies the effect locally (a Dodge tool or Brush, for example); or selecting an image area and applying the effect just to those pixels. Making a selection One method is to select every pixel contained within an area defined using, say, the Lasso or Marquee tool: these pixels can be of any value or colour. In this case, the pixels are said to be contiguous.

By the end of the eighteenth century it was known that if objects were placed on specially treated paper and left out in sunshine, a “surprint” of the object could be recorded. Later, prints were made in the same way, by placing negatives in contact with special printing-out paper.

A common problem with views taking in both sky and land is accommodating the exposure requirements of both – a correctly exposed sky leads to a dark foreground, or a correctly exposed foreground gives a featureless, burned-out sky. Problem Skies in pictures are too bright, with little or no detail and lacking colour.

There are many places that you can take a digital photography class, the first of which might be your local college or community center. Because so many people are using digital cameras now, and so few people know how to do more than point and shoot, these classes are in great demand. You can certainly learn a lot of very good basic information by taking one of these courses.

Learn about the different ways of making a selection – some are obvious, such as the Lasso or Marquee tool, but your software may have other less-obvious methods, such as Color Range in Photoshop, which selects a band of colours according to the sample you choose. Use feathered selections unless you are confident you don’t need to blur the boundaries. A moderate width of around 10 pixels is a good start for most images.

There are several ways that you can go about learning digital photography, the easiest of which is online. There are a number of very good resources that you can use to learn how to use your camera, how to distinguish which features are for you and when to use them, and also what to do with your images once you have downloaded them. Some of these resources are websites, while others are electronic books that you can download which are written by experts in the field.
