First you can use the Fast Colour Corrector and drag and drop this effect onto the timeline. You can then adjust the tonality of the clip. If your image is too dark you can add some whites, and vice versa. Then to adjust the greys and midtones you can lighten or darken the midtone areas of the video.
After this go to the Tonal Range Definiton option in the effects panel. Drop down this option and drag the triangles towards the centre because this will blend the blue and orange effects together and therefoer making it look moer natural.
The last effect to add is tint. Drag and drop this onto your clip. Then change Map Black to a very dark blue and Map White to a very light orange. Then tint 20% or 30%. This adds more blue and yellow to the imae, whilst desaturating other colours. You may need to readjust levels in Fast Colour Corrector.
This is some of the grading advice we are going to use to give our film a cinematic film and also to add blues and more colour to the opening party scene, to give it a better party feel.
