The KODAK PROFESSIONAL Extended Range Imaging Technology File Format Module applies Kodak's

Extended Range Imaging technology to images from these KODAK PROFESSIONAL DCS Digital

Cameras and Backs:

DCS 720x

Can I use imaging applications other than ADOBE PHOTOSHOP to open an ERI FFM?

The ERI FFM was developed with the PHOTOSHOP Software Development Kit. Therefore, testing was

only performed with PHOTOSHOP. Other applications may work with the ERI FFM User Interface. If the

ERI FFM fails to open an ERI JPEG file, try using Open As and selecting "Kodak ERI" as the file type. If

that fails to open the ERI JPEG file then use Open As and select "JPEG" as the file type.

What image processing options are available in ERI FFM?

Exposure Compensation Lighten or darken the image.

Balance Select and apply a Color Balance method: Preset, Click, Custom, or Auto.

Lighting Apply the illuminant that most closely matches that in which the image was captured.

Look Apply an appropriate tone scale for the content of the image. Apply Portrait to enhance flesh tones

in images having people as the content. Apply Product to images that do not have people as the content.

Reduced Saturation Product and Portrait are only valid for images captured with the KODAK

PROFESSIONAL DCS 720x Digital Camera.

Destination Color Space Select the Output Color Space that matches your output device.

I just selected an image processing option and I don't like the result. How can I get the image

rendered the way it was before selecting the option?

Press the Revert button.

Are there any cumulative (image-degrading) effects on an image as a result of selecting a

sequence of image processing options?

No. Each time an image processing option is selected, the image is fully rendered using the original

image data.

Should my monitor be calibrated to view images with ERI FFM?

ERI FFM is optimized to work with monitors calibrated to a gamma setting of 1.8. For best results, use a

monitor calibration utility to calibrate your monitor. PHOTOSHOP includes a monitor calibration utility.

Note that most MACINTOSH monitors are pre-calibrated to a gamma setting of 1.8. Images typically

appear brighter when viewed on a MACINTOSH system than on an uncalibrated WINDOWS system.

Specifying the Color Balance Method

           

The ERI FFM provides four Color Balance methods for ERI FFM images:

Auto The image is automatically color balanced by a Kodak propriety Scene Balance algorithm. No

Exposure adjustment is applied.

Custom The image is Color Balanced using balance information that the camera stores with the image . You

can save a Custom Balance file using KODAK PROFESSIONAL DCS Photo Desk, then save it to a

PCMCIA card. Load the Custom Balance in the camera by inserting the card into the camera and

loading the file.

Click The image is Color Balanced by setting the RGB value of the selected neutral point to equal code

values (gray), then making the corresponding adjustment to the RGB values in the remainder of the

image. To use this method, press the Click button and move the cursor over the image.

The cursor changes to an eye dropper.

Find a neutral spot on the image and click the left mouse button.

If the error message “Image is saturated. Try click balancing at a different point" appears:

Move the eyedropper to a more neutral point in the image.

Click again or choose another Color Balance option.

When you select the Click option, all Lighting choices are disabled until you click on a valid point in the

image (regardless of the enabled, selected state of the Link option).

Note: After selecting a Color Balance method, you may view the image with the previous Color

Balance method by re-selecting the previous Color Balance option

Preset The image is Color Balanced using preset White Balance values for Daylight, Tungsten, Fluorescent,

and Flash. These values were determined when the camera was calibrated under these different

illuminant settings.

Note: After selecting a Color Balance method, you may view the image with the previous Color Balance

method by re-selecting the previous Color Balance option.

Applying Lighting

           

You can choose the type of lighting closest to conditions present at time of capture by applying a lighting

color correction to the image. Daylight is the only lighting choice available for images captured with DCS

Pro Back and DCS Pro Back Plus models.

Daylight Tungsten Fluorescent Flash

After lighting correction has been applied to the image, the Linking option is disabled (cleared).

Link Color Balance and Lighting

           

Selecting any Lighting option automatically unlinks (clears) the Link checkbox, which breaks the linkage

between Color Balance and Lighting.

Setting the Image Look

           

You can change the look of an ERI FFM image by selecting a Look ICC Profile from the Look Profile

drop-down menu. Four choices of Kodak Proprietary ICC Profiles are available:

KodakDCSPortrait and KodakDCSPortraitReduced: Recommended for images with people as the

main content. These profiles apply a lower contrast tone scale with more detail in the highlights and

shadows. The “Reduced” profile was developed for DCS 720x images that have a natural higher

contrast than the other camera models supported by the ERI FFM.

KodakDCSProduct and KodakDCSProductReduced: Recommended for images without people as

the main content. These profiles apply a higher contrast, more vibrant tone scale. The “Reduced”

profile was developed for DCS 720x images that have a natural higher contrast than other camera

models supported by the ERI FFM.

Notes:

Other ICC profiles may appear in this drop-down menu, but there is no guarantee that they will have

the proper effect.

If you installed the KODAK PROFESSIONAL Product DCS Custom Looks, those ICC profiles are

available in this drop-down menu. Please refer to the associated documentation for more information.

Destination Color Space
