Something that I took from the sample campaign ads were the different types of variations they had. For my different variations, I changed the backgrounds to make it look more like the picture isn't just placed on by making the opacity less.
For my campaign ads, I used the masking tool to add another layer so that I could make a picture darker or brighter. But for my campaign ads, I made the flag in the background with less opacity so that the picture can be more eye catching. I only wanted the flag in the back so that it wouldn't look so plain and it would match the rest of the concept of the ads that I was trying to make. Another tool that I used was the magic wand tool so that I could get, for example, Homer because I had a picture of Homer with a white background and i didn't want the background so I "magic wanded" Homer, clicked on "select" and then clicked on "inverse" to only have selected Homer. After that, I only had the picture of Homer without the white background so if I were to put a background in back of Homer, I wouldn't have to see the white background.
For the 3 different campaign ads, I mostly changed the background and the pictures that I included in the ads. The first one that I made, I felt like I took a lot of time on over the others because I was making the "'08" out of donuts. After I finished making the first ad, I noticed that it had too much content on it. For the second ad, I liked it a lot because it shows the point quickly and it's very simple. For the third ad, I didn't really like it because the pictures didn't make sense with the idea but it was something that I wanted to try to see if anyone would like it or not.
The final version that I would probably pick is the second one because it shows a lot with little effort.
