I notice that pericynthion's picture includes a few extra bright spots on the visor apart from the main reflection of his lamp. These are plausibly reflections from small scratches in the visor, the same phenomena that now seems the most likely explanation for straydog's "footlights" in the other photo.
Good catch, flyingswan. Those are indeed scratches on the model visor. I had noticed the large curved scratch when I was shooting the pictures. I was annoyed because it ran right through the "sun" reflection. The bright highlight that appears just to the left of my head is caused by a tiny pit in the surface of the visor. I just checked the figure and verified that it's there. It's visible in that photo, but not in some of the others I shot from slightly different positions. None of these scratches are very visible unless the light hits them just right. FYI, the blueish highlights on the right side of the reflection are cause by my computer monitor and by light leaking around a window shade. Other than those (and the lamp, of course), there are no other light sources in the room.
And now, I'm off to work. Talk to you later ...
