Agfa CTprecisa 200 ISO 200 RMS 12 CTprecisa takes its name from the word precise, which translates as accurate, correct and right. This film emulsion is designed to achieve high-quality slides that capture the total color range of the original scene. Resulting images feature strong colors, soft shades and a tight grain pattern. We find people photos and scenics have uniformity of color from one scene to the next, even when the lighting changes, or flash fill is added.

Kodak Ektachrome E200 ISO 200 • RMS 12 This is Kodak's excellent medium-speed pro slide film. E200 offers the look of a lower-speed film with rich colors, very fine grain, great sharpness and lower contrast. It can be pushed to EI 400, 800 and even to 1000 with excellent results. Ektachrome E200 features excellent color rendition, natural skin tones and good detail in highlights and shadows. This is the perfect film to handle those low-light situations when you need to shoot chrome film.

Fujichrome Provia 400F ISO 400 • RMS 13 This film features the finest grain in all 400-speed slide films. Provia 400F (RHP III) provides vivid and accurate color reproduction, excellent sharpness, pleasing skin tones and a rich tonal scale. This film is a much improved version of its excellent Provia 400 predecessor. It offers good push/pull processing capability to ISO 1600. This is an ideal film for stop-action photogra-phy, photojournalism and just about everything in between. Photo by Mike Stensvold

B/W . . . Kodak Technical Pan ISO 25 • RMS 3 This film was our very first film review in March 1982. Tech Pan is still the sharpest and finest-grain black-and-white film available. It is flexible in its processing and can be rated from EI 16-320. When processed in low-contrast developers like Technidol, it yields virtually grainless images. If processed in Kodak D-19, it magically produces extreme-contrast negatives. Minimal exposure latitude, so testing is necessary for achieving optimum results.

Fuji Neopan 100 Acros ISO 100 • RMS 7 A new medium-speed, high-quality film, Neopan Acros features extremely fine grain, excellent tonal curve and superb image sharpness. The key to this new emulsion is the use of the Super Fine (Sigma) Grain Technology, which maintains small, evenly spaced and similar-sized grain. This results in a quality film that is a fine choice for all types of picture taking, especially landscapes, portraits, photojournalism and fine art photography.

Ilford XP2 Super 400 ISO 400 • RMS varies with exposure & processing This is a sharp, fine-grain black-and-white professional film that provides excellent print quality and the convenience of C-41 processing. Image quality is superb when the negatives are printed on conventional black-and-white paper. XP2 Super yields superb black-and-white negatives that can also be processed and proofed by any convenient one-hour lab. You can also develop it yourself with Ilford's XP kit. This film has amazing exposure latitude (EI 50-800), improved contrast, excellent highlight and shadows, and more neutral base color than the original XP2.

Ilford Delta 400 ISO 400 • RMS varies with exposure & processing The key ingredients in this new emulsion are its finer grain, increased film speed and exceptional sharpness. Ilford Delta 400 has expanded its processing to include a variety of chemicals, variable processing times and it is balanced so you can process both 35mm and 120 simultaneously in the same chemical processing tank. To provide photographers a creative edge, Ilford designed the emulsion so it can be rated from EI 200 to 3200 by simply altering the combination of time and chemistry concentration.

Kodak Tri-X ISO 400 • RMS varies with exposure & processing Tri-X is an all-purpose panchromatic film for subjects requiring good depth of field, high shutter speeds, and extended flash distance range. It has long been a favorite of pictorial, sports, and new photographers for its beautiful tonal range and high speed. Many users rate it at EI 250-320 and reduce development to gain extended tonal range. Tri-X is easily pushed in several popular "speed-increasing"developers. This film has medium contrast, fine grain, wide exposure latitude, high sharpness, but can only handle a moderate degree of enlargement.

Kodak Professional Portra 400BW ISO 400 • RMS 9 Chromogenic films are black-and-white film emulsions structured using color-negative film technology. This allows you to shoot very-fine-grain black-and-white images and process them in C-41 chemistry right along with other color negative films. The most interesting part of this emulsion is its five-stop exposure latitude, EI 50-1600, with no processing adjustments. Portra 400BW film sports T-Grain crystals and takes chromogenic film one step further as it is designed to be printed on color printing paper along with its color-negative counterparts.

Kodak T-Max T400 CN EI 400 • RMS 10 Another chromogenic film, T-Max T400 CN is a mix of black-and-white film T-grain technologies and advanced dye-coupler techniques used in the newest Kodak color-negative films. The result is one of the most advanced high-quality black-and-white films ever produced. The key feature of this film is that at EI 400 this film has better quality than most ISO 100 black-and-white films. Instead of using the different layers to separate the colors normally found in color-negative film, Kodak created multiple layers of varying ISO film speeds. The original image is captured in a silver image and then is coupled to color dyes in the same emulsion.
