Christen's Art Blog: Colour Correction

In media we got introduced to colour effects and controls that's can be used in changing the effects in a video. We got shown RGB- how the purpose is for sensing, representations and display of images in every electronic screens such as laptops or mobiles etc.. The RGB colour model is an additive colour model in which red, green and blue light are added together in various ways to reproduce a broad array of colours, the name comes from the initials of the three additive primary colours (red, green and blue). We also learnt about Luminance which is how the light is portrayed on the screen (light or dark). To add on we looked at Chrominance this is the strength of the colour. Chrominance is usually represented as two colour-difference components: U=B' - Y' (blue-luma) and V=R' - Y' (red-luma). We also learnt about Broadcast Safe which is the safety of the colours on the screen.

Panel menu on the bottom right hand corner

We used Premiere Pro by going to: Windows > Workspace > Colour Corrections
This then comes up with a tab where you can monitor colour corrections. On this iduidual tab click on its panel menu, it will come up with different options either click: Vectorscope, YC Waveform or RGB Parade - and it will bring up different methods of seeing colour tones.

Vectorscope:

Displays the Chrominance levels, if it goes past the green by 75% this means

it's not Broadcast Safe.

YC Waveform:

This displays Luminance and Chrominance at the same time.

1.0 = pure white. 0.0 = pure black

RGB Parade:

Displays the colour equality. As you can see in the picture there's a graph, which shows the bend of each colour. This tells us how much Chrominance of each colour is on the screen.

Also using the Jarle's Looks pre-set (made by Jarle Leirpoll) for different colour effects, adding themes to a particular part of the video created, here is our three examples:
