We had a bad bug in our dng files we managed to introduce at the last minute that made everything cyan when viewed in photoshop. It's fixed and the update will be live soon. I think the green flash was fixed in our last update (this morning?). If not it will definitely be fixed in the next one - it's fixed in the version I have on my phone.

EXIF data in the jpegs is definitely on the todo list.
