Many photographers long to achieve the perfect bokeh, although few achieve it. There are a few simple tips any photographer, pro or amateur, can use to perfect your bokeh. The first step to bokeh is the depth of your field. A low aperture produces a short depth-of-field, this causes a larger area of your image to be out of focus. Consequently, many photographers push for a short depth which could not end well. If your aperture is too low the photo isn't ascetically pleasing to your viewers eye. Another step is choosing the proper lens, with all the lens available you need to know how to make the right choice for the type of photo you intend to receive. A final tip to creating what you would call the perfect bokeh is custom bokeh! How can it not turn out perfect if you create it yourself? For your own perfect bokeh you can make a cut out preferably out of black construction paper. Then you attach it to your lens and shoot! There you go, the perfect bokeh.
