Kodak DCS Pro SLR/c Review
Software: File Format Module v18.104.22.168
The Kodak DCS File Format Module provides extended range imaging support for ERI-JPEG images loaded into Adobe Photoshop. The module itself is installed as a Adobe Photoshop file format plugin and operates by checking each JPEG opened by Photoshop for ERI data. If it recognizes an image as ERI-JPEG it displays a special dialog box which gives you the opportunity to make modifications to the image before it is loaded. The red bar indicator in the bottom left of the dialog indicates how much extra latitude is available in the ERI portion of the JPEG (above the current 'white point'). You can choose to simply continue opening the JPEG or click on 'Enable' to make adjustments.
After clicking on 'Enable' the FFM re-renders the image and enables the adjustment panes, these allow you to change exposure compensation, balance & lighting, look and color space as well as applying rotation. In the example below we have gone one step further and applied a -1.0 EV digital exposure compensation to the image, you can see the difference compared to the image above, which if it had been a normal JPEG file would have been pretty much lost.
Below are three ERI-JPEG sample images, the first exposed normally, the next two over exposed by 1.0 and 1.3 EV respectively, the camera histogram is shown below them indicating the amount of ERI data captured. Directly below are 'fixed' versions of the +1.0 and +1.3 EV images with digital exposure compensation applied to them by the ERI file format module then re-saved from Photoshop. The -1.0 EV image shows almost no degradation, the -1.3 EV image does lose some detail in areas of strong color. Overall it's an impressive performance, being able to recover just over one stop of highlight detail from a JPEG image could be a life saver for a professional photographer.
