# Interactive image comparisons
Below you can view interactive comparisons of the rendered results in the paper, using `PNG` conversions of the original
`OpenEXR` images.
## HDR version of comparisons
You can also view high-dynamic range versions of these pages which allow you to compare the original `OpenEXR` images,
with exposure control, and automatic error-maps, directly in the browser:
!!! WARNING
Because of security settings in modern browsers, the high-dynamic range comparisons only work when hosted using a web server, and not using the `file://` protocol.
To start a local web server, run one of the following commands from the root directory of this supplemental archive:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ bash
python -m SimpleHTTPServer 8000; # Python 2
python3 -m http.server 8000; # Python 3
npm install -g serve && serve -s . -p 8000 # JavaScript
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
And then launch this webpage by pointing your browser to: `http://localhost:8000/`.
The `renders/` sub-directory also contains the original high-dynamic range `.exr` files alongside the `.png`
conversions, which you can load in your viewer of choice.
