For my first photography assignment I had to take pictures of 24 crayons with each of them next to their own color. Not only was it just taking pictures of crayons next to its color, It also showed me all of the colors around us. One Challenge was finding a color for every type of blue and purple, Finding each shade was very difficult. It was also difficult to position the crayons so that they wont fall. If you use tape on the crayons it could be noticeable by the glare of the tape. Some things that I found easy was finding brighter colors such as green, yellow or white.
