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.

Enjoy!

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.

Learn the VIEW CAMERA at CCSF!

This fall semester, I'll be teaching View Camera again at CCSF.  It's on Saturday afternoons.

This is a great class for students who have taken a darkroom class before, and want to expand their knowledge of photography.  The view camera is a very versatile tool, and a must for those who want to continue with a career in photography.

Some of the benefits of the view camera:
  • Film based - no digital capture 
  • Large format film records more detail.  
  • You can process one picture at a time for more control
  • Ability to control the placement plane of focus
  • Ability to control perspective and distortion
  • Easily create multi-exposure pictures
  • Optical tricks - disappear in the mirror
  • Get an instant print with an Fuji instant film back.
  • Cool factor - you'll look great sporting one of these cameras!

Photography class = employable skills?

As the semester comes to an end, do you ever wonder if all that film processing was worth it?  I mean, if everyone does digital now, what's the point?

Well, there are lots of good answers.  First, film offers you control over every aspect of your image.  You decide exactly how you want it to look, then use your skills to make it happen.  You are not relying on automatic functions and filters.  Your photographs will not look like the many other people that bought the same DSLR.  Your photographs will reflect the physical action of your hand in exposure, processing and printing.

There are also lots of arguments about quality and longevity.  Digital files are not as stable as film, and there is a big risk in that.   Film that becomes damaged may still give an image, but a digital file is often  completely lost.  Quality is another factor.  Film is superior in quality to any digital sensor of equal size. Cost, while seeming more at first, is actually less expensive.  You can use the same film camera for decades, while a digital camera expires in only a few years.  And, digital backs for large format cameras are way too expensive!

Now, you're wondering if film photography will give you any employable skills.  The answer is, YES! I recently came across this very tempting opportunity for a large format photographer.  It's pretty much a dream job, and only those with view camera skills can do it!

So, View Camera class, do you think you've learned enough to try a job like this?  I've shown you all the skills you need, and the rest is up to you.

CCSF: printers down

Hi View Camera Class,

I just found out that PK1 is down and that only leaves one 4800 printer.  If you are planning to digitally print your final portfolio, I strongly suggest coming in today because tomorrow may be quite busy with just one printer.


Also:  The morning class has priority for both printing and darkroom from 10-12:30am.  Please plan accordingly.
