sometimes i wish i could snap my finger then tadaaaa things are in front of me shortly. But nothing just happen. Just like Amerie says, "Sometimes you gotta work hard for it".
"everything is knot a torus"
(tho, not all of these qualify as knots, unknots included as well. so, clearly: not everything is knot a torus)
The Ben Day process involved screens with raised dots or patterns that could be painted with ink or other media and then burnished onto prepared areas of an exposed zinc plate before etching, a photographic negative before exposing onto a prepared metal plate, or even onto artwork or ad material before it was photographed for the printing process. A complex and unique process, it appears in use from the late 1800s through the 1980s—maybe beyond in specialized industries or printing plants that didn't update.
On this page, a standard form of the device is shown with details about what tints and patterns are available. It appears to be from
The page shows at the bottom the printed results of applying 40 patterns to photographic negatives before etching and then printing. Compare No. 532 on this page with the identical No. 532 in the next image in this sequence. A 20% tint applied as a layer of pigment to a negative means that 20% of the exposed area is opaqued out, leaving 80% clear. When exposed onto a photosensitized plate, the clear areas harden. During etching, only the unexposed portions wash away. As a result, the relief plate used directly for printing (or through duplication in the stereotype mold/plate method) have 80% of the area covered in tint.

1. Image out of camera, 1/4 sec at f/1.8, WB 2700K.
2. White balance adjusted in UFRaw (Linux).
3. Red and Blue channels inverted in CS5 (channel mixer).
Image taken with unmodified Nikon D300s using Nikkor 35mm f/1.8G lens and Hoya R72 IR filter. In camera WB was 2700K, exp. 1/4 sec at f/1.8... ISO 800 Exp. Bias +5.
Image was moved to Linux for White balance and tint adjustment in UFRaw with GIMP. This is roughly the equivalent of Halogen correction.
Then moved to W7 for CS5 channel mixer, where red and blue channels were swapped for a more natural look. In Channel mixer, red channel, change red +100 to -100, green from 0 to +100 and blue from 0 to +100. Blue channel, change red from 0 to +100, green from 0 to +100, and blue from +100 to -100.
I've made these charts because I couldn't find any reliable information on how to expose a film for this "reverse xpro". From these results, I like something between -1 and 0 best - it may however be different with other films.

Week #2 Square and Processing
Examples of different processing results. Depending on your experience, these can be done manually or with reset actions in image processing software (I use Photoshop).
(top left) Cross processing uses layers, contrast and variations in color balance to give a "yellowish green" hue to the image. You can do it manually, but Photoshop has an action (macro) that is simple and quick. I've used it on anything from landscapes to portraits in the past.
(bottom left) High Dynamic Range was processed using Photomatrix, a popular and proven application available online. Some cameras have in-built HDR options. Again, it can be used on a wide range of images and the intensity can be dialed up or down. Some HDR images are quite stunning but processing can also be over cooked (an HDR term!). Flickr is full with different results and it's up to personal taste what you prefer.
(top right) Black and white/Mono can be achieved by using fast and easy single click "GreyScale" or you can manipulate the histogram to isolate color bands and keep tighter control over the result. Curves can be also applied to control contrast.
(bottom right) Orton processing is a controlled blurring or softening of the image achieved by combining 3 layers in Photoshop. Again, it comes to personal taste to apply Orton to images. It can be applied over the whole image or used to soften different areas.
Enjoy...and good luck with your processing.
Strange, heavily processed picture of Nobuo. The first processing was turning the original image into a half-tone image (a rather heavy-handed conversion because, why not?) then I ran that result through one of the dreamscape-like filters on-line and this is the result.
Experimented with some cross processing in Aperture.
If you want to try it, go here for a good how-to article.
Vignette added.
Image transfer on watercolor paper done using Citrasolv cleaner. It's very addictive making these little transfers.
