Image 1 Uses an additional white line to bring more attention to the strong curves of the photo. The large white circular shape in the bottom creates more negative space to put more attention to the top of the image. The typeface used has similar curves and has unity with the rest of the image.
Image 2 I created rectangles on the sidewalk to create different color tones on the bottom of the image and make it a little darker. The word is grid backwards and upside down and is the concept of the image. The white line is used to strengthen the grid in the image.
Image 3 Is playing upon the different textures in the photo as well as the interesting perspective. The gradient is used to appear as if it has a light source on it.
Image 4 Using additional lines to put more emphasis on the grid as well as lead your eye to the model. Contemplate is using a really clean typeface to go along with the geometric tone of the image
Image 5 Uses additional negative space to draw more attention to the strong lines created by the cables. The text is used to play upon the city scape.
Image 6 Uses a filter to give a completely different feeling to the photo making it more nature like and organic with the range of brown colors. The texture of sky loses its feeling of the clouds and more so looks like an organic pattern created in the ground. The white lines of the power line and birds give the photo context and give it connection to an actual photograph.
