My first images to present (below) are contrasts of each other and work very well as a set of two. I have two ideas to start with, one where each image is on white foam board and the other idea is they they are in black window mounts. You can see the two designs below and I have decided to go with the black window mount. When using the diagrams below, I liked both ideas however the black mount make the colors more prolific and allowed for a nice contrast between the white in the water and the black mount.
My next set of images to present are different, I plan to have a set of 3 images in a line sitting next to a larger image. I have two very similar ideas for this one, as you can see below. You see the set of 3 on the left on top of an extra foam board to make them stand out (3D) and the image on the right is not, however on the second idea the image on the right is also on foam board. In the end, I decided to follow the second idea and have the image on the right on foam board as well and the set on the left.
