logo for Chichago photography

Chicago photography is a photo studio based on Chicago. it's not a traditional photo studio that people always see, it's a creative photo studio that offers sports, news, wedding, fashion photos to their clients. They are searching for a modern, simple, dedicated logo that like the company does. The logo should communicate the image of the company and not just a logotype. So, the criteria I concluded are:

1. communicate the image of the company
2. not only logotype
3. the logo should simple, modern, creative

From the sketches of the ideas, I picked 3 ideas that fit to the criteria. Actually, the second one is the simplified version for the first one. The former two ideas are a combination of  camera and the capital letters "c" and "p". The third one adopts the frame aiming at objective when we take photos.
And finally, I picked the second one as the logo, because it's simple, modern, and can represent the feature of the company.
