Why are there two connectors on the back of the scanner?

The scanner is designed to be part of the SCSI chain with other pieces of equipment, such as a camera or printer. The scanner does not have an internal terminator. If the scanner is the last device or the only device on the SCSI chain, use the terminator supplied with the scanner to terminate the SCSI chain.

 

What type of light source does the scanner use?

The scanner uses LED technology to provide consistent scan-to-scan image quality. Various combinations of color (R, G, B) diodes eliminate the filter wheel and Wratten filters used in earlier Kodak Professional RFS Film Scanner models. This dramatically improves scan speed and reliability.

 

Is dots per inch (dpi) the same as pixels per inch (ppi)?

Yes, the terms are interchangeable.

 

What is dithering?

Dithering is a procedure that mechanically moves the Charge Coupled Device (CCD, or imaging sensor) so that each imaging element on the CCD captures information from four adjacent areas on the image.

 

What is dynamic range?

The scanner provides a high-quality luminance density range of 3.5. This is determined by using a Q60 film target where it is possible to discern between gray scale steps having densities of 3.3 and 3.5.

 

Can I create custom film terms?

Yes. You can create custom film terms and save them to match specific shooting conditions.

 

What if my scanner needs service?
