Colour Theory and Correction

For our project I had to do lots of colour correction as we were filming a conference which was lit by mixed flouorecent lighting and the images came of as very yellow and green.


In the art world RED BLUE and YELLOW are the primary colours, meaning you cannot make them by mixing any other colours together.
By mixing them together you get secondary colours as showed in the picture above.
By mixing secondary colours with the primary colours you get tertiary colours (The Interaction Design Foundation, 2018)

Colours can be also divided into:
Complimentary - meaning they are opposite to each other on the colour wheel (like red and green)
Analogus - meaning they are 3 colours beside each other (like sky blue, blue and purple )
Triadic - meaning they are 3 colours, equally spaced out over the colour wheel (like green, yellow and purple)

However, this method is used only by artist to mix paint, the primary colours on digital screens are RED, GREEN and BLUE, also known as RGB.

This colour wheel makes yellow, magenta and cyan their complimentary colours which are used to colour correct an image. (99designs, 2018)
As I mentioned before the footage we got was on the yellow/green side so to correct them I needed to add more of magenta and blue to the images. 
While colour correcting it is easier to focus on correcting the neutrals like whites and greys to look more natural to the eye. (Apogee Photo Magazine, 2018)

I've also found that the lumetri scopes on premiere pro can be really helpfull in acheving the best coloured images. As it shows what are the main picture colours and the graph on top left corner lets you see how much complimentary colour you should add, to get the most natural looking image the waves should look as white as it can and the white splaters on the bottom colour wheels should be mainly in the middle. (Odisho, 2017)

Influences DOPs and the genre

BEN DAVIS DOP in numerous superhero films, such as Kick-ass, Guardians of the Galaxy, Avengers: Age of Ultron, Doctor Strange, and Captain Marvel. The films I want to focus more on is Kick-ass and Captain Marvel because the audience gets to see how the main characters become superheroes and that is more relevant to our project "The 7 Billionth Hero". In "Kick-ass" all of the superheroes are just people who don't have any special powers. The Protagonist decides to become a superhero and fight crime and starts a new superhero trend.  There's a lot of interesting POV shots  Mirror POV, when he's practicing what he's gonna say to the bad guys. Phone camera    I particularly like this film for lighting. Most of the fight scenes are filmed in low light and there's a contrast between his everyday life and his superhero life. It's bright, warm and slightly yellowish, but at the same time is very monotone to show the boredom a...

Project evaluation

For something done last minute it isn't the worst, but it could have been better if I haven't put it off.  If I've done this on time, I still could have refilmed some scenes that would have made it better and more believable (the scene in the car).  Script wise I have no idea. Am I proud of it? No, but I give myself points for trying. Is it bad? Probably. Is it a complete dissapointment to me? No, because even if it's really bad, it gave me experience that I didn't have before and even though I never want to write another screenplay again I can learn from my mistakes and hopefully when I have to do something like this again - I'll be better at it. Probably the most important thing I've learned  is that I need to figure out a way to manage my time and don't let things pile up.  As well as while taking out the kit - grab a light, because even if I end up not needing it, I'll have an option to use it and it would make filming way easier. I regret...

Camera workshop (coverage)

In one of our camera workshops we learned about the importance of coverage. It doesn't matter that in the end we won't use all of the footage and maybe even end up using just few shots, it's important to have multiple shots from diferent angles so that we would have options while editing.  During the workshop we had two exercises. One of which was "The Chair": It ended up being pretty short video and I ended up not using half of the footage I got for it. For next exercise we were given scripts and had to interpret it in our own way.  While editing I wished I would have filmed few more close up shots and to have actually filmed the whole scene from fixed camera positions.
