Patrick, from within your model, you can access the file that was
uploaded. It is probably a temporary file on Heroku, but that's OK,
since you just need to parse something from it. Here is an example:
model Photo < ActiveRecord::Base
has_attached_file :avatar
before_save :process_exif
def process_exif
avatar.file # this is where you'd have access to the file
directly for processing
end
end

Thanks, John. I've read about folks using ImageMagick output in the
same way.
But I haven't found any straightforward documentation on how to
accomplish this.
(Paperclip + S3 + locked file system on Heroku is complicating this
a bit).
