Week#6: 10/12/11 Printing

"Sitting over a hot computer ain't my idea of fun. My creativity goes almost completely into picture taking. (But) I suppose if I ever retired, I would enjoy learning the Photoshop craft far more than playing golf." - Herbert Keppler - On going digital. (Popular Photography & Imaging, January 2005)

" Focus on content.. be color blind." - Lakshman Iyer

Motion

A photograph is a small moment in time.  Depending on your shutter speed (and other factors!), you can capture a small moment of time or a longer one.  Within that slice of time objects may be moving.  And depending on the below factors, you can capture moving objects either frozen in mid-movement, or completely blurred.
 
Motion is controlled by these factors:

1.       Shutter Speed:
Faster SS = Less Motion (Frozen)
Slower SS = More  Motion (Blur)
2.       Focal length of lens:
Short FL (zoomed out) = Less Motion (Frozen)
Long FL (zoomed in) = More  Motion (Blur)
3.       Subject Distance
Far Subject = Less Motion (Frozen)
Close Subject = More  Motion (Blur)
4.       Speed of Object:
Slow Speed = Less Motion (Frozen)
Fast Speed = More  Motion (Blur)
5.       Direction of Object:
Moving Towards Lens (into camera) = Less Motion (Frozen)
Moving Parallel with Lens (across picture) = More  Motion (Blur)

*The important factor is how much of the images actually moves across the image sensor during exposure.  The more of the sensor that your image crosses while the shutter is open, the more the image will be blurred!


Today we'll be talking about proper color management workflows and how to take an image from monitor to print with as much color accuracy as possible.

Colors on a monitor are displayed using a combination of RGB light, while printed colors are typically created using a combination of 4 inks CMYK.  Because the RGB and CMYK color models use different methods to display colors, each produces a different gamut, or range of colors. 

The color space for a device is defined by the gamut it can produce. And an ICC profile is a description of a device’s color space.  The profiles are used to help ICC systems communicate properly and translate your color gamut from device to device accurately.

Color Management Workflow:
STEP 1:  Calibrate your monitor
STEP 2:  Set up the Photoshop Color Management Environment
STEP 3:  Assign a Profile to the image
STEP 4:  Soft Proof your image on screen
STEP 5:  Print your Color-Managed image using ICC Printer Profiles

Below is a handout detailing the proper color management workflow steps for printing to an Epson inkjet printer.
