Sometimes doing slit lamp photography is like taking
pictures of ghosts. We are called upon to make images of vitreous prolapsing
into the anterior chamber or cells and flare. These are things that are
marginally observable and prove to be as challenging as photographing a snow
leopard in Winter.
If you know the response of the camera and know how to
control both the slit lamp instrument lighting and a proper response for the
camera, you can make the invisible visible. In some cases a camera adjustment
can fix some exposure problems and in some cases you can massage the data with
post processing tools to get a better looking image. I will attempt to
demystify both approaches with examples of when it works and when it fails.
