For day 4 of the Online Card Classes Copic Markers for Card Makers, the lesson was about lighting and how to shade an image depending on the direction of the light source. Lighting and shading is not something I have given much thought to when it comes to coloring but it can add some dimension to an image. The lovely floral image for this lesson was fun to color. As you can see on my practice sheet below, I used various colors on the flowers. For the top two images, I envisioned my light source was coming from the top left, trying to keep the lighter color on the left side. On the bottom two flowers, I decided that the light was beaming straight onto the flowers. Also, to color the petals, I used a flicking technique as shown in the lesson, to add the appearance of texture. The lighting and shading concept is something that will definitely take some practice but as long as the image looks good to you, there's no need to stress over it. Have fun coloring!
