Can someone explain in more technical terms why this looks so much better than the video shot by the Galaxy Nexus? Something about the quality is so much more inviting and warm. Is it just the production or is the camera actually better?
1. Shallow depth of field (close objects in focus, far objects out of focus). Doesn't necessarily mean poor quality, but webcams have wide DOF, so you might associate shallow DOF with good quality
2. JPEG compression- I see more compression artifacts in the Nexus video. This isn't related to camera quality at all.
3. Sensor quality looks better to me. Details in the dark rear-view mirrow, more detail in the sand.
I honestly don't think it looks better. I am a fan of "proper" color balance, not cross processed type filtering (instagram, lomo, toy cameras, etc). And I think the OP's is definitely better in that regard.
