Certified Professional Photographer (CPP) Practice Exam

Which type of film produces a dye image rather than a silver one?

1. Color negative

2. Dye transfer

3. Chromogenic black and white

4. Color reversal

The correct answer is: Chromogenic black and white

The film that produces a dye image rather than a silver one is the dye transfer film. This process is significant because it uses dye to create the image, rather than relying on silver halides that react to light, which is the typical method for producing images in traditional black and white photography. Dye transfer films utilize a process where dyes are transferred to paper to create the final photograph. This method allows for vibrant color reproduction and can also yield high-quality prints that have a continuous tone. The other types of film listed, such as color negative and color reversal, primarily create images through chemical reactions involving silver, which do not yield dye images. Chromogenic black and white film, similarly, also incorporates silver halides, thus excluding it from producing a dye image. Understanding these distinctions enhances the knowledge of photographic processes and their outputs, which is crucial for any professional photographer looking to expand their repertoire and successfully navigate the Certified Professional Photographer exam.
