Edit: isn't whole stage black thanks to residues from engine burn?

Couple of questions, can anyone tell if the legs deploy? Is the stage not plumb to the water or is that a misperception?Matthew
So is that what the grid fins are for, to help keep the stage straight as it falls?

The grid fins will be able to control the stage in the long flight phase when the engines are not running. They can do precision steering by forcing the stage body to a desired angle against the airflow, creating a steering force.
Regardless, they must be getting damn close if CRS-4 is going to go for a barge landing.

And as for this gimbaling, are you saying the engine bell is able to literally move? I thought it was completely rigid?like this pic shows?
Looks like the camera ship is one of these:http://www.diamond-sensing.com/index.php?id=da42mppguardian
