Here are a few of the powerful new features of InstaMask:
? We can create 18, 16 bit luminosity masks. These are done individually so they keep our file size to a minimum.
? Going further, we can also build these 18 masks around any of the Red, Green or Blue channels, so we have a total of 72 masks at our disposal.
? We can intersect any of these mask with each other. So we can add/subtract any mask to/from the RGB channel, for example, with any mask from the Red, Green or Blue channels, should we wish.
? We have two new point-and-click methods for developing advanced selections based on colour or luminosity. We simply click on an area of the image and a mask will be built around it. And we can refine these masks even more with + and ? buttons, which restrict or loosen the selection.
? InstaMask has 3 convenient sliders which compliment a 16bit workflow, allowing us to craft our masks to the perfect selection.
? There are also a whole range of new colour masks.
? We can apply any mask to any layer. Taking this further, before applying the mask, we can test it on any layer and make adjustments as need.
? With split screen, we can use our sliders and adapt the mask, while also see the direct change on the image itself.
? With all of the apply buttons, we have more or less everything type of layer covered, so that we can apply our masks to and adjustment layer.
