In order to create this image, I first had to find my 3 images that I was going to use. Following the locating of my images, I opened them in 3 different Photoshop documents, and then moved them onto my poster document via layer copy. After that, I did some highlighting, brightening and cropping in order to make my images more visible.
After editing my pictures the way I wanted, I put my main image in the background and dimmed it in order to give the 3 smaller pictures the main lead in the poster. Once that was completed I pasted my 3 main images where I wanted them, and created the yellow borders around them. My last step was then to create my text. I added a little bit of a shadow behind them in order to add a little more 3D and voluminous effects.
