Last week, we discussed about Filter Blur. Today we will look into second type of blur available in filter option of CS6 – Iris Blur. In Filter Blur, we applied blur with the help of pins. In Iris blur, we again use similar multiple pins but here we have more control on how we want to apply the blur effect than in field blur. In each pin, we can define area covered, angle, density of blur to be applied and also change the shape of the area selected. As in field blur, in Iris blur also – we can apply as many pins as required in an image and those pins can be moved easily by dragging in required areas.
