These are certainly darker than usual. I'm musing on the fact that pictures of music seem to somehow missing a critical part of the experience; I wonder if a 30 second video clip would be more enlightening for the curious reader. Or has this been considered but rejected?
And that's after increasing the exposure 3x in Photoshop Mobile. Hemlock has basically no lights at all.
A video clip would have been even darker than these (since there are no exposure controls for iPhone video) and would have sounded like I had just tossed my phone into a clothes dryer (if my experience with watching video clips on Youtube is any indication).
