For this assignment I used my own picture.
In Photoshop I used the Art Board.
For contrast I used dark blue and red color to highlight a due date for registration. For writing I used two fonts and two sizes.
For repetition I used the same typeface for the the announcement and the words students need to pay attention first.
For alignment I tried to achieve the balance between the information and the image trying to keep the writing on the same distance from the edged of the poster.
For proximity I tried to keep the distance between individual elements.
