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?
Update
I count 4 blaster shots in another version (link lost), based on visual and sound effects. The last one is countered with Vader's left hand, instead of his right like the others.
One is deflected around and scorches the wall next to the left side of the doorway, from Vader's viewpoint.
Another scorch mark is very briefly visible on the wall to Vader's right, just next to the rectangular wall ornamentation. However, this scorch mark disappears when we next see the wall (from the outside of the room). At the same time, Boba Fett is inexplicably standing behind Lord Vader.
I never noticed the other mark until now, rewatching the clip over and over to count the blaster bolts.
However, this editing snafu makes me wonder if additional footage exists (that may show Boba walking into the scene) that gives us a different viewing angle.
