What does Lobster do?
Lobster works inside Photoshop to accurately separate the tonality and colour of your image using the Layers palette.
Lobster creates four new layers from your RGB image: Luminosity (a very specific type of tonality) and Red-Green-Blue Chromaticity Set. (Covering Hue and Saturation).
This separation allows a "divide and conquer" approach to the editing of your images, where for example changes can be safely and accurately made to your Luminosity layer without affecting the Hue and Saturation of your file - an action not possible in Photoshop.
Lobster gives you new uses for and insights into the following elements of Photoshop:
Levels, Curves, Selective Color and all other Adjustment Layers.
If you are using any of these elements in your regular digital practice - you should be using Lobster!
Lobster also offers new and more accurate choices for many tools but particularly the Dodge, Burn and Sponge tools.
At long last the Info Palette gives you results that match the prescribed description of many operations. The Color Wheel, Color Picker and principles of Luminosity can be used to predict and make sense of many Photoshop operations.
Lobster is not a plug-in, filter, or separate application, but a companion application that works within Photoshop using its built in capabilities to achieve a highly complex outcome. Your files remain in RGB and only a copy of your file is changed by the Lobster process.
