J.L. Morton's talks about the basic color theory starting with a brief overview of what color theory is then moving onto the concept of 'the color wheel'. He explains primary, secondary and tertiary colors with both imagery and text description. He also talks about the importance of color harmony in which he explains that color can clash and need to work in harmony with eachother, this information helps me in deciding on colors that I can and can't use with my promotional video. I do not have a strong artistic or persuasive creativity in me so reading the basics has opened new ideas to me. As to whether he backs his points up he does reference Sir Issac Newton, 1666.
As someone that doesn't know too much about color schemes nor really cares about fashion I would recommend this website to gain a basic understanding of how color theory works and all the aspects revolved around it.

Source 2: Psychology of color.
Ciotti, G 2014, 'Color Psychology: How Colors Influence the Mind', blog post, 20 August, viewed 13 of July 2018

<https://www.psychologytoday.com/au/blog/habits-not-hacks/201408/color-psychology-how-colors-influence-the-mind>
Gregory Ciotti's article starts with addressing misconceptions about the psychology of color and how it spikes conversation but has no scientific evidence in the background to support any theory. He mentions how each person corresponds particular colors with memories or emotions, color branding. There is also reference towards gender color preferences. He explains preferred colors of men and women colors and disliked colors for man and women.
This information is relevant to me due to how I am promoting an artist. They have created a large variate of art work over their years and if I am to appeal to one's attention through color and by catching the audience's eye.
Although this blog post is old, I would recommend it to someone that is interested in the human mind and how color influences actions. However, the references are blanked out and I can not link the research towards anything, this effects the liability of the text.
source 3: How to make a promo Video
Ruffell, C. 2012, '5 Steps: How to make a promotional video, step-by-step guide', Reel Marketer, Viewed 24th of July 2018, <https://www.reelmarketer.com/how-to-make-a-promotional-video/>
Christopher Ruffell shows how to make a promotional video with only 5 steps. He clearly shows a summary and later expands on the information provided in great detail. The 5 steps are: Strategic planning, Pre-production, Production, Post-production, and Distribution and Marketing.
Personally, I like the way the information is set out. I found the material easier to read and follow due to the brief example and expanded example. It gave me the mentality that I know what is going to be covered without having to dig deeply for the information that I desired. With this source, I now have a better understanding of how I should approach my promotional video and how I should go about planning it.
I would honestly recommend this source due to its easier ability to communicate with it's reads and has it's viewers in mind. However, it is a long read if you want to get in-depth with the information, if not, then a simple read to help one get on their way.
Source 4: How to make quality content
Jefferson, S. and Tanton, S. 2015, Valuable content marketing: How to make quality content your key to success, 2nd addition 2015, Kogan Page Limited, United Kingdom,  <https://books.google.com.au/books?hl=en&lr=&id=bzISCgAAQBAJ&oi=fnd&pg=PR7&dq=How+to+make+a+Promotional+video%3F&ots=ambjAuwFb2&sig=MEzyoUw1sBMxI_1cY7BBLw_Nt64#v=onepage&q=How%20to%20make%20a%20Promotional%20video%3F&f=false>
Honestly don't think I can summaries this source... It is REALLY long. The index shows a lot of what is going to be covered but hard to compress. Sonja Jefferson and Sharon Tanton tells us why we should look into valuable content, What is valuable content, and How to supercharge your business with valuable content. Honestly has really good content but a heck ton of it. In truth I haven't finished reading this source but with what I know about it it helps me focus on something valuable for the promotional video rather then showing everything I've got.
Would I recommend it? Depends. This source is massive! If someone was keen on learning about business and marketing then yes I would recommend it. This source has a lot of credible and reliable information if one is willing to read all through it. If they are not so keen and are looking for something more simple then no. I would not recommend this source towards someone that doesn't have a massive interest in business or marketing.
Source 5: How to shoot a professional video
Hiner, J. 2017, How to shoot professional video on an iPhone: 3 tips, Tech Republic, Viewed 23rd of July 2018. <https://www.techrepublic.com/article/how-to-shoot-professional-video-on-an-iphone-3-tips/>
Jason Hiner expresses 3 simple points about recording any form of recording, audio and visual. With simple tools like your iPhone one can make professional videos with no problems and he shows it in 2 ways. 1. the written form, and 2. a video expressing the same 3 points. Easy to read, follow, and provides me with more recording options, which really helps me due to not having a recording studio or booth.
I would recommend this source to anyone interested in photography or recording with a low budget because Hiner states that you don't need $300 equipment to get good quality results.
