Visible crew/equipment: At Tia Dalma's, two large white rectangles - either a light fixture or the reflector screen - are reflected in the glass bottle, which hangs beside Jack's head. (00:49:50)
Visible crew/equipment: When Jack opens the compass on the deck, two round lights are reflected on the lid. They are obviously stage lights, since from another point of view neither the sun nor any type of light is seen.
Visible crew/equipment: While Norrington and Will begin their duel, Jack walks away and promptly falls into the open grave. In the shot of Jack from within the grave, the imprint of a modern, flat bottom trainer/sneaker sole can be seen on the dirt wall (yes, wall) to Jack's left. It is not the imprint of a shoe of the time period. (01:48:00)
Visible crew/equipment: After Will is captured, when Jack first opens his make-up laden eyes, the white square reflections of the reflector shield is visible in his eyes; as it is in other characters' close-ups as well. (00:25:05)
Answer: Yes, the idea is that this poor soul got too close to one of the Kraken's tentacles and one of the suckers pulled his face off. Presumably he can still breathe in some fashion, something has been left that allows air access to the lungs, allowing him to still be alive, although it doesn't sound like he's long for this world, so presumably the damage is extensive.
