Did Vader deflect, absorb or block Solo's blaster?

This question has come up in the comments of Why don't the Jedi use tutaminis instead of using their lightsabers?

Here's the relevant clip: Han Solo vs Darth Vader encounter on Cloud City

Some think Vader was using tutaminis or absorbing the bolts.

Some think Vader was deflecting the bolts.

Some think Vader was blocking the bolts by either strong armor or a Force shield.

In the video, it's evident that at least one blast is deflected, because you can see it hit the wall (by the door) that leaves a scorch mark. However, the other shots are unaccounted for visually.

Is there a different view (wide-screen VA standard), behind-the-scenes, extra footage, script indication, or official novelization description that provides insight to account for each bolt fired from Han Solo's blaster?
