Kodak E-24 manual Exposure, Processing, Equipment, Printing Color Negatives and Internegatives

EXPOSURE

Equipment

Expose this film with optical- or contact-printing equipment. For large-scale production, you can use printers and copying equipment modified for production applications.

Use exposing equipment that has a tungsten-halogen (3200 K) light source, a heat-absorbing glass, an ultraviolet absorber (such as a KODAK WRATTEN Gelatin Filter No. 2B or a KODAK Color Printing Filter CP2B), and built-in dichroic filters.

Printing Color Negatives and Internegatives

KODAK VERICOLOR Slide Film is intended for exposure times of 1⁄4 second to 8 seconds. Set the illumination level at the exposure plane to 16 footcandles (172 lux) without a negative or filters in the light beam. Use an initial exposure time between 1 and 4 seconds.

To print negatives made on Kodak color films onto VERICOLOR Slide Film, use a starting filter pack of

20M + 30Y. Negatives made on daylight-balanced films exposed with tungsten light will require more yellow filtration.

The filter pack is based on average emulsions of KODAK VERICOLOR Slide Film. See the film carton for supplementary information on each emulsion. This information includes starting filter-pack and aperture adjustments. The aperture adjustment includes the exposure adjustment required for the filters.

Because of the variables involved in producing internegatives from different types of transparency films, make tests to determine the best filter pack for printing internegatives onto KODAK VERICOLOR Slide Film. Start with a filter pack that produces successful results in printing original camera negatives and adjust filtration and exposure as required.

Making Reverse-Text Slides

You can use KODAK VERICOLOR Slide Film to produce reverse-text slides with white or near-white letters on a dark or colored background. To make a reverse-text slide, photograph dark letters on white background with color compensating filters over the lens. For backgrounds of various colors, use the filters and exposures given in the tables below.

Use a 3200 K light source. To determine the shutter speed and lens aperture for exposure, use an incident-light meter set at the exposure index indicated below. When you add the filters in front of the camera lens, increase the exposure as shown in the tables. Make an exposure series of at least

±1 stop in 1⁄2-stop increments. Keep the exposure time between 1 and 8 seconds.

Note: Reverse-text slides exposed with KODAK WRATTEN Gelatin Filters usually have more saturated colors than slides made with KODAK Color Compensating Filters.

Using KODAK WRATTEN Gelatin Filters

Use an Exposure Index (EI) of 8 with no filters over the light source. Place the WRATTEN Gelatin Filter over the lens.

Background	KODAK WRATTEN	Exposure
Color in Slide	Gelatin Filter No.	Adjustment*
Red-brown	None	0
Purple	12	2 stops
	(deep yellow)
Dark blue	12 + 85B	2 stops
	(deep yellow + amber)
Cyan	29	4 stops
	(deep red tricolor)
Dark green	34A	4 stops
	(violet)
Red	38A	4 stops
	(blue)
Orange	44	4 stops
	(light blue-green)
Dark Yellow	47	4 stops
	(blue tricolor)
Magenta	61	4 stops
	(deep green tricolor)

*You can increase exposure by extending the exposure time, as long as it does not exceed 8 seconds.

Using Color Compensating Filters

Use an Exposure Index (EI) of 2 with a filter pack of CP60R + CP50 over the light source. Place the color-compensating filters over the lens.

Background	KODAK Color	Exposure
	Compensating
Color in Slide		Adjustment*
	Filter
Magenta	75G	1 stop
Blue	50R + 50Y	11⁄2 stops
Cyan	70R + 05Y	0
Dark green	50M	1 stop
Yellow-orange	90B + 40C	2 stops
	Remove the CP
Dark red	filter pack from
	the light source.	0
	Add 90C + 20G in
	front of the lens.

*You can increase exposure by extending the exposure time, as long as it does not exceed 8 seconds.

PROCESSING

Process KODAK VERICOLOR Slide Film in KODAK FLEXICOLOR Chemicals for Process C-41. Do not process this film in washless minilab process cycles, i.e., Process C-41B and C-41RA. This film is of an older design that requires a stabilizing agent for image stability. Process this film only in a processor that uses KODAK FLEXICOLOR Stabilizer III and Replenisher.

For information on processing, see KODAK Publication No. Z-131, Using KODAK FLEXICOLOR Chemicals.
