UNIT II: Raster
PROJECT: Split through the center we press forwards
OBJECTIVES:
· To gain experience in the use of additive light techniques.
· To use computers as a tool for creating art.
· To become familiar with process color printing, and understand the differences between CMYK and RGB color via studio lighting, digital photography, and Adobe Photoshop.
· To gain experience in working as part of a two person collaborative team.
PROJECT:
Working collaboratively, photographs of an alter ego arrangement are shot and manipulated to create a four color/ process acetate print, using digitally produced color separations.
READING:
· Launching the Imagination Chapter 4 Illusion of Space (cmap)
· Digital Design Media Chapter 6 Images (read)
· Adobe Photoshop help screens for halftones and color separations
VOCABULARY:
additive system, RGB, computer color, HSB or HSV, optical mixtures, pixel, bitmap, vector, subtractive system, process colors , process materials, transparent media, actual color transparency
MATERIALS:
· Alter ego costume and props.
· Access to a computer, two 8 ½ x 11” matte boards (one black and one white), rubber cement or staples, tape, CMYK acetate prints.
· Digital cameras
PROCESS:
Preliminary:
Before coming to class, review the thematic concept of Collaboration as found on the website. Also read the discussion on Additive Light for Unit III and Media for Unit X on the Artcore website. Review the Project References above.
Step One:
· Write a paragraph description of your alter ego. What are their personality traits? What do they usually wear? What is their favorite food / restaurant? What is their most prized possession?
· You will be put into pairs based on your alter egos
· Set up a still life of you and your partner’s alter egos paying close attention to good design within the composition. Be sure to include at least a piece of your body in the composition (if you would like your entire body in the shot go for it!).
· Find another pair to take a few picture of you and your composition.
Step Two:
Change a copy of your image to CMYK color –You may continue to work with your partner at this point, but you must each have a copy of your recorded observations and a unique version of a print. You must also each use a different photograph of your setup.
· The image has been scanned in RGB color for general use on a computer, but we want to change a copy of it to CMYK color for printing the transparencies.
o Open Photoshop. Open your file from your disk or the shared space.
o Go to Select > All
o Go to Edit > Copy
o Go to File > New
o In the new window go to Edit > Paste
o If you want to alter your image in Photoshop, do it at this point.
o Go to Image > Mode > CMYK color – when it asks if you want to flatten the image, do it.
Note the slight change in color go back and forth between modes to see the change again. Not all colors possible with RGB are reproducible with CMYK, and vice versa.

o Record your observations on the differences the change in color mode makes.
Step Three: Look at the color separations
· In Photoshop, it is possible to look at the separations before we print them.
· Follow these steps and record your answers for the CMYK copy of your photograph only.
o Select Window > Channels
· 
A new window titled Channels should now appear to the right of your screen.
A new window titled Channels should now appear to the right of your screen.o Clicking the name of the channel will make a channel visible or invisible. Click on the names of the different channels (Cyan, Magenta, etc) to see what they look like in black and white. What happens when only one color channel and black are selected? (Select multiple channels by holding down the SHIFT key while you click) What happens when different combinations of color channels are selected? Play around and try different combinations.
· Record your observations.
Step Four: Create HalftonesIn order to print the image with a silkscreen or other printing process the image must have a halftone or other graphic code on separated channels.
· For great halftone effects you must first make sure your image is at a high resolution.
· Go to Image > Image Size…
· Set the Resolution to 180 pixels/inch or higher.
· Copy each channel (Cyan, Magenta, Yellow paired with (K) Black) into a new window.
· In the Channels window select a channel (C, M, or Y) by clicking on the channel name (the channel must be visible – have the eye icon next to it).
· After selecting the channel hold the Shift key and select the channel for black. You should now have 2 channels selected.
· Go to Select > All
· Go to Edit > Copy
· Go to File > New
· In the new window Go to Edit > Paste
· You should now have a copy of your image with only one colored layer and a black layer.
· Delete the content of the black channel by clicking the name of the channel. Go to Select > All and then press the Delete Key on your keyboard.
· You should now have a copy of your image with only one channel visible.
· Go to Filter > Pixelate > Color Halftone
· The appropriate channel must be selected in the Channels Window.
· Be sure to play around with the settings to get different effects.
· Repeat the above steps for each channel (C,M,Y, and K).
· Print each half toned channel (C, M, Y, and K) separately onto transparency film. I recommend getting your transparencies printed at a local copy store. They will already have the transparencies on hand so there is no need for you to purchase any.
· Play with the size, making sure all your images are the same size, but make sure that you leave enough room for your matte frame. You probably don’t want the edges of your image to be cut off by your frame.
Step Five: Combine the Prints
· Use rubber cement sparingly (clear tape, or staples) around the top edges between transparencies to join them into a single image. Play around with the order of your transparencies for the best result.
· Adhere to the center of a clean, white matte board.
· Cut the center out of your black matte board to make a frame.
· Tape the edges together on the inside of your matte board.
· Photograph your finished piece and post it to the blog.
Critique Ideas: Points to discuss might involve the following:
· What are the conceptual reasons behind creating multiples?
· What differences are there between smaller and larger images?
· Did everyone use the same shape of halftone (and how does that affect the final image)?
· What type of images work well for this technique (drawings, photographs, level of detail, original color/s)?
· Is the color/ reproduction accurate; were images registered correctly; were the color/ separations in the right order, etc?
GRADING: (24pts)
| TECHNICAL: (6pts) Did you use the resolution, bit depth, and color mode the assignment called for? Are there mismatched shadows or other examples of poor digital craftsmanship? Do you have all the halftone layers? |
| AESTHETIC: (6pts)Are your final pieces compositionally balanced? Did you make good use of color? Does your piece lead the viewer’s eyes? |
| CONCEPTUAL: (6pts) Does your final piece address the theme in a clear way? Is the “whole more than the sum of its parts”? Does your final image address the themes proposed for this assignment? |
| RESPONSABILITY: (6pts) Were you prepared for each class? Did you bring the rough sketches/ideas on the due date? Did you upload your image to the class blog on time? Did you work during work hours? |
