Creating
the Erotic University Galleries
Viewing a painting on
your computer is nothing at all like viewing an actual painting. Pictures
you have seen a thousand times printed in a book or online can take your
breath away when you see the real thing in a gallery. We knew that we could
not recreate the experience you'd get in a real world gallery, so we decided
to take advantage of what computers do best.
Every
image in our galleries has been optimized for viewing on the computer,
but we took it a step further. Old paintings suffer from the dimming of
their colors and their alteration due to changes in the canvas itself.
Color prints in books can suffer additional color quality loss as the pages
of the book yellow. Since old books are an important resource for providing
source material to scan from, this can make for images that are very different
from what the original painting or illustration looked like. Many of the
original photographs also suffer from color shifts (a lot of green in an
image might cause yellows to become greenish looking). Take a quick look
on the Internet for classic paintings and you'll see a lot of them that
look grayish, faded, yellowish, or have other color problems. They are
clearly not what the artists intended.
Some
of the images in our galleries may be ones that you have seen before, but
you may be surprised at how much brighter and cleaner the colors are. Every
one has gone through digital image processing (dynamic range extension,
color balance, color channel correction, sharpening, brightness and contrast),
to attempt to restore them to what we believe is a close approximation
of the original look. Of course, it is a guess, and it is impossible to
get the colors exactly right without seeing the original and researching
the methods used to create the original painting. Even then, the differences
from monitor to monitor would defeat any attempt at true color fidelity.
The
images in our gallery are clearly superior to the original image we started
with, though, as the examples below demonstrate. Just
click on them to see the color correction take place. These are small images-
the effects are much more noticeable in the full sized images in the gallery-
but we think this will give you a good idea of what we mean.
We
also used line removal and scratch removal features to get rid of cracks,
repainted in some damaged areas, and did whatever we could to make the
image appear as close to what we thought the original would have looked
like. The two bottom images show details from the full image. Look closely
at the horizontal defects in the image bottom left near the bottom of the
image (especially along the foreground character's hip) and the vertical
defects in the image bottom right.
Clicking on these original
images will slowly transform them before your
eyes into the digitally
restored version. (Requires the current Flash
plug-in)
Refresh the page to return
them to their original state.
The final piece of the puzzle
is compression. JPEG is the standard way to compress a picture, but too
much compression can leave areas of an image looking blocky. Too little
compression and the file size of the picture is too big. Paint programs
save to standard JPEG, but we ran all of the images through special software
that uses dynamically increased compression on areas of low detail and
less compression on areas of high detail, resulting in significantly smaller
file sizes at much higher quality than a standard JPEG.
Finally,
we use Flash to display the pictures, which makes it easy to browse through
the galleries using the arrow keys on your keyboard. The pictures
load very fast into an easy to use interface.
