Alright well this is to be the first of many blog posts showing different aspects of photography, firstly the extreme basics then moving on to some slightly more technical things to add some unusual creativity to your photographs.
I decided to start with selective focussing as all it needs is a standard lens with a relatively wide aperture and subjects at different lengths. Selective focussing relies on the depth of field, which is the section of the photo that appears sharp and in focus.
To practise using selective focussing find two subjects; one to make the main focus of the photograph and one to be blurred. Set the aperture of the camera to f5.6 or lower (the lower the number the more out of focus area will be displayed). Make sure a correct exposure is used by balancing out the shutter speed.
Now using the focus ring, make sure the object you want to stand out is focused as sharp as possible and press the shutter.
Here I focussed on the flowers just above bottom of the image leaving the landscape to be blurred.
If you wish to make the other subject the main focus. Simply use the focus ring to make it sharp and take the photo again. Here I took one with the landscape focussed.
Feel free to post any feedback on how helpful this was, any problems or your own Depth of Field / Selective focussing shots.
