Sinisa Drpa has introduced Effect Stack, a non-destructive image editor for Mac OS X. It requires Mac OS X 10.9 Mavericks or later and costs US$9.99.

Effect Stack allows users to chain multiple image filters. It offers a choice of a variety of filters that can be stacked together and saved as pre-sets that can be re-used.

The filters’ effects ripple downward through the stack, changing the current stack of the selected image or images. Effect Stack supports all image formats supported by OS X. Go to for more info.
