With this picture I added an orange border because I believe this is the color that pops out the most in this picture. I used color range to bring out the metal and the colors in the warning label. I used color balance to play with the mid tones, highlights, and shadows. I also used vibrance to bring out the lighter colors in the image. I was trying to brighten up the image more  and bring out the shadows.

I just added a border and corrected some of the background.

I used color range to bring out the rust on the pole and some of the shadows on the grass and the bowling pins. I used color balance to play with the color. I finally added the border.

I used levels and vibrance for this image. Then I used curves after using vibrance. After that I just added a border and that was it.

I used vibrance on the image first. After the vibrance, I used curves to make the shadows darker and the highlights lighter and brighter. Then I went to filter and used craquelure to make it look sort of like cracked paint. After that I just added a border.
