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...

Studio Idea

Personally, I found it really difficult to come up with an interesting studio production idea. But because "one idea is not enough" (Brown and Duthie, 2010)  I came up with 3 initial ideas: 1) Guess the song type of game show, but instead of guessing pop songs, the contestants would have to guess classical music. I got this idea from a game my friends and I loved to play and the way my music teacher used to test my class.  2) Travel guide about how to make the most of your trip, places worth visiting and places that are overrated and not worth your time. I got this idea from my sister who travels a lot and from the way she does loads of research about each and every place she visits. 3) Debate/Game show where 2 groups of people debate about nerdy topics ( whats better Marvel or DC, which Doctor was the best etc.). The idea comes from noticing how much rivalry there is between comic book lovers and overall 'nerds'. I feel like this idea is the stronge...

JVC camera

During our studio production rehearsals, I was behind the JVC camera. Everyone in our camera crew agreed that it was the best to stick by one camera and master working with it instead of bouncing from one to another. I've never worked with a JVC camera so it was tricky to figure out. The first day I picked it up felt like my first day in uni when I knew very little about cameras, it took me ages to find the on/off switch. To help me better to understand where I can find all of the settings and buttons I took the camera out. I wanted to go through the settings so I would be confident in knowing where I can find certain settings if needed. Before that, I couldn't find peaking on it which helps with keeping everything in focus especially when people move more. Found out that if you turn the peaking on you can only see things in black and white and the peaking colour, of which I wasn't a fan, but at the same time I found out that you can increase peaking on the...
