Image sym is odd

[edenvicary]

So I'm doing a

BW::Camera.any.picture do |result|
  mp result

and the result is

{
  :"\e[4mOriginalImage\e[0m"   => #<UIImage:0x11c749fb0>,
  :"\e[4mMediaType\e[0m"       => "public.image",
  :"\e[4mReferenceURL\e[0m"    => #<NSURL:0x11c74dbd0, URL="assets-library://asset/asset.JPG?id=5291A6BF-EB16-43A6-9C56-CF80F8E49C17&ext=JPG">
}

When I try and access it by result[:original_image] like the API describes, it returns nil. So any ideas why I can't use it the way it's shown in the readme?
