LiveGrade Air gives DOPs and DITs the freedom to create and visualize their color ideas in preparation for their next shooting day by just using an iPad or iPhone. In order to change the look of the image, select a grading control by tapping on it and simply swipe on the display to adjust the look.
The Basic Controls in LiveGrade Air offer multiple adjustment controls over the image:
- Brightness: adjusts the overall luminance of the image.
- Pivot: The Pivot control allows you to change the center of the contrast adjustment. Around the center the contrast will remain the same.
- Contrast: used to increase or decrease the contrast range of the image.
- Tint: balance between green and magenta tones on the image.
- Temp: setting used to give a warmer or cooler look to the image.
- Saturation: adjusts the color intensity of the image.
Alternatively to the Basic Controls mode, LiveGrade Air also offers Color Wheels. The Color Wheels are the classic ASC-CDL controls available in many color grading applications. This mode offers the following settings:
- Offset: Offset raises or lowers overall brightness of a component. It shifts the transfer function up or down while holding the slope constant.
- Power: Power is the only non-linear function. It changes the intermediate shape of the transfer function.
- Slope: Slope changes the slope of the transfer function without shifting the black level.
The different controls have two settings: color and level. The color setting is modified by swiping the display, and the level is set by rotating with two fingers.
The Reference button lets you toggle instantly between your graded image and the ungraded image (by default). You can also choose another image from the library to compare the grades. Alternatively, it’s possible to compare the current image with the False Color representation of it (in-app purchase). These settings can all be set in the Image Grading Options panel (figure 3), by tapping on the «Compare To» item.
The grades can be reset completely with the «Reset Values» button available in the Image Grading Options menu (figure 4). If only one of the settings has to be reset, you can tap on a grading control for 2 seconds and the reset menu will pop up (figure 5).
