Photoshop : Iris Blur Filters


Original Image

One of the nifty things about the BLUR FILTERS in the new Photoshop 6 is that you can apply more than one IRIS filter at a time. This in essence allows you to concentrate the blur areas where you want or need them, leaving the un-blurred areas alone.

When you get ready to begin the process you can place as many BLUR FILTERS down as you like and then you can view the MASK you are creating by pressing the “M” key to see the mask.

You can press the “P” key to toggle between the preview mode and the original of the image. Once you have the blur areas identified you then need to consider whether to add “bokeh”.

When you do this you will need to juggle the amount of blur being applied across the image with the threshold values of the bokeh and also the colors of the bokeh you are willing to allow to form.

When you visual inspection gives you what you want you confirm by pressing the return key. The blur calculations being and when done you will have a new image.

You can click on either of the images to the right to enlarge it for visual inspection. Note that one additional step was taken here. I created a duplicate layer under the blurred layer. It was from the original image. I gave the blurred layer an opacity of 75% and that made all the difference in having the blur effect be more gradual than I was able to achieve with the four iris blur filters that were applied.
