Research - Colour correction/grading

Recently aside from my college work I am working with a professional director making a short roman film. My job on the team is to help be a runner on filming days and also be the films graphic designer. Whilst chatting to the director we began talking about the colour in films and he recently had just finished the colour correction/grading in the film. I had never come across this term in my research so I was interested to know more about it. I found out it links into making video look like film and overall giving a better look to the film. He showed me the before and after video of the colour correction/grading and I found it fascinating. I decided to research it for our short to see how it's done and how it helps. 

Take a look at the definition of colour correction. Colour correction is manually tweaking each clip to get the best possible light and colour. it is a very 'tedious' way of improving your film however looks very good once finished. It takes a lot of work and is considered an art form due to the fact it is personal preference. Often colour correction is used to make the clip look like the temperature of the film for example if they're in a mountain area then you use blue and white for coldness. Also it could include things such as relighting the set or correcting your film. An example is if you're filming throughout the day and the sun is going down but it's still the same time in the film as before, you can correct it and make it look better. The point is to make it look like the eye sees.

Now colour grading is a similar but more detailed process. Colour grading is the next step and changing it further by altering an image and making it more to fit the scene. An example is fitting the mood of the characters so if the character is angry making it a subtle red. (This is a shocking example and wouldn't look good at all but you get my point). They both make it look better and both should be used. In our film I think this is very important as it turns the film from an actual film to a professional film but first I think we need to test it first.
