 Eraser |
| The eraser is a very powerful tool it can erase brush strokes as well as any changes done to an image. The eraser can even erase away effects or adjustments. For example you could apply the black and white effect to a color image then erase away portions you would like to have in color which will expose the original colored areas, leaving a very cool effect. |
 Fill |
| The fill tool uses the currently selected color to fill the whole image with color. Selecting a semi transparent color then using this tool can be used as a simple tint effect. |
 Eye Dropper |
| The eye dropper tool lets you select a color that is current on screen. When using this tool it changes the currently selected color to be the color you touch. |

Filters are accessible by clicking the filters button. The filters menu will appear showing filter adjustments and filter effects.
| Curves |
| Curves is an excellent tool to control the contrast and brightness within various tonal spectrums. The slope of the curve dictates the contrast of the image while the absolute value of the curve represent brightness. The curves tool is usually used for rearrange contrast between different tonal spectrums. Curves can be edited in RGB, CYMK or CIE LAB color spaces. |
| Levels |
| The Levels control gives users the ability to custom configure black and white point in an image or within a color channel (the left and right nob below the histogram). In addition, it also offers the ability to set the gamma value of the image/channel (the middle nob below the histogram). This tool effective controls when highlights and shadows start to clip, thus allowing the user to maximize the contrast of an image. Levels can be edited in RGB, CYMK or CIE LAB color spaces. |
