When ever we look at a photo, objects that are in focused will pull our attention. Cameras and lenses were developed to produce high quality image with brilliant focused. Object can be focused by either fully auto- or manual-focus. This can be done by a click of a button. Photo with images that look out of focus are usually due to cheap lens, sensor issue, vibration, aperture versus focus point issue, high ISO or that’s what the photographer want it to be.

Out of focus images can be valuable if it was done with a careful plan. These photos are categorised as abstract image. Abstract images are suitable for large print for the living room or bed room, or as background for posters, slide of presentation, webpage etc. The quality of out of focus images is usually depending on the shape of images. This shape is highly influenced by the number and shape of blades of the aperture in the lens. Some lens will give you images in the shape of pentagon, hexagon and totally round. Which shape will be the best? The answer is all of the shape. It is actually up to you because this is an abstract image.

How to do this abstract photo? It is actually not that difficult. Lenses with focal length of 55 mm or higher are usually preferred. Set the lens to manual focusing mode. Target your camera at the image, set the lens at a high focal length, then turn the focus ring to a maximum either to the left or to the right and snap. Preview the image produced and choose your desired photos. Try them! J
