Looking at a Camera Lucida

Most of you have heard of a camera obscura before.  It's that pre-photographic tool that was used to make accurate drawings in the days before photography.  But what is a camera lucida and how is it different from a camera obscura?

Well, a camera obscura is a device that is basically a darkened room.  That's where it gets the name.  Camera comes from the latin word for room or chamber, and obscura comes from the latin word for darkened.  So a camera obscura is a darkened room.

Lucida is a word that comes from the latin word for bright or light.  And so, a camera lucida is a room that is bright and lucid.  That's because it can be used without being in the dark.  So a camera obscura and a camera lucida are completely different.  They really don't have any relationship except that they are both pre-photographic tools that are used to make accurate drawings in the days before photography.

The camera lucida was invented in the early 1800s.  It was was used by scientists, artists and travelers to get a very accurate drawing of the world.  Back then, if someone wanted a picture of something they saw, they had to draw it because photography wasn't invented yet.

A camera lucida works by creating a kind of superimposed image over the top of the drawing paper.  It isn't a projection, it just kind of looks like it.  A person looks through a prism to see both an image of the drawing paper and an image of their subject at the same time.  Then all they have to do is trace what they see and the picture looks pretty good.

I just posted a new video of a camera lucida in action.

Film or Digital? Why not both!

Ever since the arrival of digital media, there has been a debate about whether to use film or digital.  But is doesn't have to be just one or the other.  In fact, many professional photographers are enjoying a combination of both methods!

Film capture and digital output allows a photographer to enjoy all the unique color traits of film photography, without sacrificing the advanced editing that digital methods allow.  The film can be scanned at a high resolution to create a quality digital file.  The file can then be edited and shared in the virtual world or it can be sent for digital printing.  

Film photographs keep their natural color beauty when scanned.

Though there is a larger investment in each piece of film, the overall cost can be lower for the film/digital workflow.  Digital cameras are in constant need of replacing, whereas a film camera will continue to work with little maintenance for a lifetime.  

Film to digital is also an economical option for photographers using medium or large format.  Medium format or large format digital backs for cameras are too costly for most artists, and even most professionals.  By using film capture, a photographer can continue to enjoy all the detail of the larger capture area, without having to spend $20-$50 grand at B&H.

By keeping the film, the photographer has a highly stable, archival back-up storage method.  This is much more reliable than a digital only workflow.  With digital, there is a constant fear of programming failure and aging.  A damaged or outdated digital file is often unrecoverable, but a scratched negative can still be saved.

I recently finished a demo on film scanning with the Epson 750 scanner.  Enjoy!
