title: Edit Meta Data of Image Python
body: <p>I am taking a picture with opencv, and all of the image properties of the pictures it takes are not set. I need to set the camera make, model, and focal length. I am using python 2.7. I have looked at piexif, but that doesnt have the properties I need. Additionally I have looked at pyexiv2, however the pip install failed when I tried to install it for python 2.7. So how do I edit the meta data of an image in python?</p>
