As a photographer and tutor I am starting a series of occasional ” Photo Pointers” articles on this blog to give some guidance to those finding their way with photography. I will avoid using too much technical language or lots of formulae and numbers.
For those who would like to go into more depth I will be running workshops during the year and can also arrange 1 to 1 or small group sessions to suit. Please email me email@example.com and I’ll be happy to discuss your requirements.
A couple of days ago I posted a trio of colourful images on my Instagram account which provide a simple example of the ways a photographer can change the focal point of the same scene.
For this set of pictures four highlighter pens were stood up on my desk, each an inch or two apart.
This first photograph shows just the pen that is nearest to the camera being sharp with all of the others looking blurred because they are out of focus.
To create this effect you set focus on the nib of the blue pen either by using the manual focus on your camera, or using automatic focus and placing the camera’s selected focus point exactly on the nib.
Setting a wide lens aperture will make sure that only the one pen is sharply focused and the wider the aperture you set on the camera the less of the image will be sharp, this effect is strongest when you are close to the subject.
The second photograph is similar to the previous one but the camera has been focused on the nib of the yellow pen and the same technique used to make sure only that pen is sharp.
The final image in this set has both the yellow and red pens sharply focused whilst the closer blue and furthest green pens are out of focus (not sharp).
To create this effect the lens is focused at a point between the yellow and red – this is fairly easy to achieve by focusing manually but it using automatic it is possible to focus on an object temporarily placed at the point where you want to focus and by keeping gentle pressure on the shutter button keep the focus set to that point, remove the object and take the picture. The real benefit of digital cameras is that you can take lots of shots making little adjustments until you are happy with the result. This kind of experimentation is really helpful when learning new techniques.
