# Direct On-Screen Grading

Direct On-Screen Grading consist in the ability to control most of the color correction tools in CineDream by clicking and dragging directly over the image in the main viewer and the scopes.

You can select a tool using the button in the top tools layout or with a hotkey.  For tools that affect global parameters like exposure or temperature, you can click anywhere on the image and drag up or down.  But those that affect exclusively a luminance range or a color, click over the area of the image you want to change and CineDream will automatically know at want luma range or color you are pointing at and modify its parameters.

For example, select the shadows/midtones/highlights tool with the Shift-E hotkey, click over the image, and CineDream will know if you are pointing a shadows, midtones or highlights area and modify that specific range as you drag up or down.

This same principle applies to the shadows/midtones/highlights saturation tool, Color Wheels, Curves and HSL.

Further more some of the tools have modifiers that are shown at the bottom left corner of the viewer once the tool is selected. For example by clicking H you select the HSL tool. If you click over a color and drag up or down you’ll be modifying its hue, but if you press the Option key while dragging, it will modify the Luma, and by pressing command it will modify Saturation.

Direct On-Screen Grading can be applied to the scopes too.  Click over the waveform, parade or histogram scopes to affect exposure, color balance and saturation.  Use the HSL tool over the vectorscope to affect hue, saturation and luma of specific color ranges.
