The Star Filter Plugin for Photoshop was developed to simulate star lens filters (also known as cross screen filters) - it adds star streaks to lights and highlights in an image. It can create a 2, 4, 6, or 8 point star filter effect. (or any number from 2 to 8) It also allows you to adjust parameters such as angle and falloff while seeing the results updated in real time.

Because highlights in digital photos are often clamped, we added a highlight boost feature to extend the dynamic range of 8 and 16 bit/channel images. The filter also handles HDR (high dynamic range) images correctly.
