Teacher: Kenji Tachibana Digital Photography I Art Copy: Class work project Target: Target can mean anything from printed text, graphics, photo, painting, or even a computer screen. For the class ‘copyArt’ project, I will provide the targets. The target will be a high resolution full color published (CMYK) photographic image with sharp text.

Teacher: Kenji Tachibana Digital Photography I Art Copy: CMYK 4-color printing process CMYK: Ink based process Only four inks are used to create the illusion of full color by commercial printers. When you use an inkjet printer at home, you’re using the same Cyan- Magenta-Yellow–Black inks. Its their relative mixture that creates all the other colors, values, and tones.

Teacher: Kenji Tachibana Digital Photography I Art Copy: Conversion (translation) Translation: RGB to CMYK You originally captured a small part of the real world into a digital camera color space referred to as RGB, Red- Green-Blue. The computer display is also based on RGB because the digital camera and the computer share the same direct light based image. When printing a digital image, it gets translated from RGB to CMYK ‘color space’ because printing is based on reflected light. RGB light based colors are naturally more vibrant than the CMYK reflected light based colors.

Teacher: Kenji Tachibana Digital Photography I Art Copy: Print output CMYK Printing: There is no way that the final printed output will have the ‘zing’ of the light-based-image viewed on the monitor. This makes choosing the right printer, ink, and paper combination very important. If you’re concerned with archival issues, expect both the ink and paper to cost a lot more. The photographic output industry (labs and lab machines) is at a point where making-your-own-print has become questionable. I personally use the Costco 1-Hour Lab when I need prints. As a bonus, Costco prints are long lasting and water proof.

Teacher: Kenji Tachibana Digital Photography I Art Copy: Commercial Poster: In order to show you the printing ‘dot’ structure, I shot a close up of the movie poster taped to a Blockbuster window. And then, I enlarged a small section from the close up shot to show the printing dot structure (overlapping circular pattern).

Teacher: Kenji Tachibana Digital Photography I Shooting Artwork NY Times Magazine: This high-production photo-illustration cover- shot was done by an advertising studio photographer working with his/her team. My educated guess is that the light-stream is either partly or fully ‘retouched’. This was a found-shot at my MONTLAKE library.

Teacher: Kenji Tachibana Digital Photography I Shooting Artwork Technique: Camera technique must be flawless. That means things like exposure, color, and corner to corner sharpness must be error free to allow the viewer to see the original art work.

Teacher: Kenji Tachibana Digital Photography I Shooting Artwork Class Assignment: You will be provided with a different ‘original art’ mounted flat on a black mount board. Mounted art work is usually a lot easier to shoot than an art work which is not truly flat.

Teacher: Kenji Tachibana Digital Photography I Art Copy: Watch out Take Care: To.. Use a normal to portrait telephoto (11 to 23 mm) focal length (zoom lens) range to minimize image and lens distortion potential. If the exposure is correct, the tonal range will be well within the exposure graph range. Use the custom WB setting to get the color balance perfectly matched to the light source. This assignment must be done using a tripod. And the camera framing must show about 3% of the background surrounding the black mount board.

Teacher: Kenji Tachibana Digital Photography I Art Copy: Watch out Most Important: The shape of the artwork must remain true. Do not introduce perspective distortion. To do so, the camera must be positioned dead-center to the art work. If your camera is not centered, the following will happen. Shoot UpShoot DownShoot Left.Shoot Right Shoot UpShoot DownShoot Left.Shoot Right If you start to combine Up/Down with Left/Right, much more exotic shapes will result.

Teacher: Kenji Tachibana Digital Photography I Art Copy: Turn In Artshare: ‘copyArt’ Folder: Turn in one (1) fully lab worked file. That means that the image must have the following Photoshop image adjustment Layers: 1.‘cropFrame’ Layer 2.Levels Adjustment Layer 3.Brightness/Contrast Adjustment Layer 4.Color Balance Correction Layer

Teacher: Kenji Tachibana Digital Photography I Art Copy: Must have details I will look for: 1.Look like the original art work based on my CRT monitor in my office. In order to do this properly, you must look in the ‘calibrated’ folder at the various image for tonal and color clues… 2.Be sharp as the original. If this is so, I should be able to see the printing press pattern when enlarged to Photoshop 100%.

Teacher: Kenji Tachibana Digital Photography I Art Copy: Must do but… Class Grade: As I have stated in some of the recent classes, I am not looking to lower you grade. If your assignment performance is higher than your current class grade, I will be happy to raise your class grade based on a spreadsheet calculation. If your performance is less than your usual past performance, I will leave your grade unchanged.
