[TheForge] RE: Layout tools

[Walter Mullett]

When I was in college, before PC's and digital, I used to do architectural
renderings in a similar way.  I would do a rough study model and take close
up pictures of it in B&W film.  After I developed these, I'd mount the
negatives in a slide holder and using my projector, I could either trace the
image on paper or just expose blueprint paper and develop a large image to
work with.  Using this as a background, I freehanded a perspective complete
with people, trees and cars.

For those without CAD, you can also shoot real B&W photographs of a site,
project that image on blueprint (or blackprint) paper, expose to ammonia to
develop it and draw your 3d design directly on the paper.  If you have
photos in color, just use the color negative.  Exposure time is pretty long
( 20 min +/- ) because the light in a projector doesn't put out enough UV.
I used a fully darkened room and taped my paper on the wall.  You inspect
the image from time to time to see if you burned off the yellow in the areas
to be white.

The results of this were very good at the time but CAD has sure improved my
life.

Hi Chuck, I like the proportioning thing, as I use an opaque projector to
fit a lot of my sketches to full size.  Having something you can overlay a
digital picture on, then add or delete items to the pad, then shoot to full
scale sounds like an extremely handy tool.

Being the size of a standard piece of paper works for the projector as well.
