Photography techniques – focus stacking
by Tony on Aug.31, 2009, under Photography Techniques, Photoshop Techniques
This articles looks at a lengthy and complicated procedure to render every part of a scene with perfect focus. the aim is to achieve a high depth of field (DOF) whilst maintaining the high quality of your lens' sweet-spot. The main challenge is, maybe, deciding what situations exactly would require this sort of treatment. This technique is popular for macro work, where the DOF is usually too shallow to capture all the sharp detail in a subject. Landscape could benefit as there is a requirement for sharpness throughout the scene. Usually an f/16 and careful hyper-focal calculations will achieve this. For my first attempt, I chose a landscape scene with a huge focal challenge. In this scene the immediate foreground is just a few inches from the front of the lens.

This place is a must on any trip to Iceland!
The glacial lagoon is now Iceland's deepest lake at a depth of 200m. The huge lake holds tonnes of ice that has broken off the Vatnjökull Glacier. It is the only place where ice actually makes it from the glacier to the open sea. The ice on this lake is 1000 years old.

Photography techniques – playing with water
by Tony on Aug.22, 2009, under Photography Techniques
We have all seen the photographs of waterfalls or beaches where the water has turned to milk. You either love it or your hate it, but regardless of that, it is a good way to come to understand shutter speed. this article looks at ways to give water that milky effect. First you need a camera and a source of flowing water. Not all of us are lucky enough to be living in Iceland. Next it is best to have a tripod or another way of keeping the camera perfectly still.
Photoshop Basics – noise reduction

No camera is perfect. If we push it to the limits of iso and low-light scenes, we are going to experience the number one weakness of a digital camera - NOISE.
Composition – following and breaking the rules
by Tony on Aug.19, 2009, under Photography Techniques
The rules of composition are guidelines for producing a well designed image. 'Guidelines' are probably a better description than 'rules' as they just help us as a kind of starting point. Do not break the rules until you are an expert at following them. You need to understand how they work and how they help you create great compositions. Learn the rules and then break them only if it will create a better image than if you followed them.

There are many reasons why you might want to crop an image. You might want to make a smaller file size, you might have straightened an image and you need to correct it,or maybe you want to improve the composition.
Photography Basics – photography as communication
by Tony on Aug.18, 2009, under Photography Techniques
Photography is all about communication. Communicating a scene or an object is similar to communicating in writing. It makes more sense if there is an order. Sentence take if we a... Sorry, if we take a sentence and jumble the words up, it has the same contents, but the meaning is lost. At the other extreme a poet can arrange the words to provoke feelings and thoughts outside of the sentence. In a visual way a photographer has to arrange the subjects/ objects in a scene so that they make sense, and artists will arrange object/ subjects in a scene to provoke emotions.

On a DSLR there is a choice of settings that allow you to have different levels of control over the camera. First you need to consider what you want to do, or to be precise, what kind of result do you want to achieve?
