I Googled a picture of a candle flame and put in on the given layer in Photoshop. As the background was black, I simply changed it to Linear Dodge with 100% visibility, then I duplicated this layer and changed it to Screen before smudging it with the help of Gaussian Blur (using setting 7). This gave the flame a bit of a glow. Now I just had to adjust the appropriate visibility, which was 60% for me.
After this I created the stripes over the flame using the Knoll Light Factory plugin (http://www.redgiantsoftware.com/products/all/knoll-light-factory-pro/). I opened a new page and filled it black and with the help of the Knoll Light Factory plugin I generated a sort of Chroma Fan (this needs to be added to the existing tools!) (Fig.11).
