(Before viewing: My visual goal was to have a lot going on, so keep that in mind when you look at it.)
The social issue I decided to address in my project was civil rights-- both past and present. I've taken images from the opposition to women's suffrage, pro-segregation groups, as well as religious fanatics that are now opposing the marriage and gender equality movement. The theme I wanted to convey was that these groups were headed and driven by the "majority" of America. Equal treatment under the law was not granted to these people by the government; instead, their rights were largely subjected to popular vote, which allowed to narrow-minded majority to oppress the minority for some time. I hope to argue through this piece that the civil rights of any person should always be protected under the law and not be abused by those that outnumber them.
I went for a more grunge-type look to tackle the weighty subject matter. I chose the particular flag image because it was reminiscent of blood/injury (maybe think Faith Ringgold's
The Flag is Bleeding?). The old typewriter font went along with the grunge look, but I decided to stray into Helvetica for "FREE" merely for contrast's sake. I haven't decided if I will be keeping it this way yet.
Here's a version using only Helvetica font:

I included the woman at the center as a victim of such oppression. I withdrew her more from the bleeding flag, but she still has the suggestion that she has been hurt by the actions of those around her. The other figures are in grayscale mostly to suggest their narrow mindedness. I wasn't sure how to create that feeling visually, but them lacking color seemed an appropriate way to go about it.
Technique:
I started by finding the images I wanted to use for the background. I found it
here, and ended up adding more stripes to the flag by selecting the bottom 3-4 red stripes, creating a new layer via copy and dragging down in place below the original. I merged the layers and cleaned up where they met using the clone stamp tool on about 60% opacity.
After that, I did a Google image search for the woman at the central position. When I found it, her back was cut off right below the shoulders, and her left shoulder was virtually nonexistent. I solved this problem by using the clone stamp tool at 100% opacity to sample sections of the skin on her back. Once I had expanded the area covered by her back, I went back over some of the rougher areas with the healing brush tool to smooth out some of the transitions.
After cutting out the rest of the activist images, changing the saturation to zero, and arranging them in the piece, I duplicated the flag layer and dragged it on top of all the activist layers. I wanted the flag design to be overlayed upon them, so in default blending mode, I selected color overlay (at 80% opacity). This gave the effect seen here. I then duplicated the flag again for use with the central woman. I wanted her effect to be a little subtler so I had to use a separate instance of the flag. I did this by making a clipping mask of the flag over the woman. I then used the color overlay option again, but this time reduced it to 40% opacity.
Feedback is appreciated.
