As BounceNY stated above, it's not easy to identify warped rotor just by looking at it. Even a minor warp (not noticeable to naked eye) can cause vibration during braking.
If I were you, I'd replace the rotors and go from there.
Control arm bushings can cause vibration; however, I'd bet warped rotors.
