I usually shoot JPEG+RAW (on the cameras that support it), bias the exposure 2/3 down and bracket 2/3 of a stop on either side. That adds up to a lot of bits!

Someone else who knows what they're talking about (not me) will have to chime in here, but about the only thing I haven't been able to fix with JPEG editors like Corel's Paint Shop Pro (~$50) has been blown out highlights, and I don't think RAW helps there. Maybe I need a Photoshop lesson!

I'd have to see pix from those smartphones to comment on them. I'm kinda picky.
