Color grading and GoPro color grading LUT.

We study color grading on Wednesday. 'SpeedGrade' is a very useful software for color grading and color correction. A good color of film can promote film storytelling.  Color grading need to adjust saturation, contrast and exposure in the first. Basically, color grading has two parts, the first part is primary correction, the second part is secondary correction. The primary correction is a basic correction for entire picture on layer. LUT( look up table) is a good way to change RGB line and modified color. Then the imagine of color adjust contrast and balance. Making a mask need to build a new layer. It is a easy way to set area. Follow that step, mask should be manual track the area. Finally, it is a secondary correction, a new secondary layer should be set up and manual adjust hue and skin tones. After that, deleting LUT and do primary correction and add LUT. It is a good way to change color correction. I try to use color finale to adjust my footage. I will post it lately.

We use 'Color Finale' is Final Cut' a plug-in for color grading. I find a footage that has a very bad color temperature then I use it to color correction. As you can see I think its better than before. But I am not very satisfied, because the white balance really hard to get it. So I use 1 hour to make the footage more natural. The video is a comparison effect. 

In addition, GoPro color grading has many ways to make it better, someone use GoPro studio but it is not very professional software. Some people teach you how to color grading GoPro footage. For example, saturation+30%, exposure highlight+5%，vibrancy 1.05, hue 355°，sharpness 2.5. The method is a kind of formwork but not suitable for all the footage. I found a video that looks like very professional. The video use Premiere pro to color correction and grading. It is use a lot of shape mask in the footage, coz the footage include many objects to be individual adjustment.
