Some members on another forum suggested that. This has about a half EV boost. The thing is, now highlights are starting to clip. This is the reason I didn't choose more exposure to begin with. I suppose a 3 bracket blended exposure might have worked better.
It is a bit dark, what settings did you use? I try to keep ISO as low as possible, and aperture out of the low range (I'll usually choose 18-22), and let the rest take care of itself (aperture choice for me is to get sharp lights, usually with starbursts... I prefer that to fuzzy light)
