Questions may be mailed to Rich- ard Lee, c/o The Michigan Daily, 420 Maynard St. Q. If I want color prints as the end products, what kind of film should I use?-Karnen M. A. Kodak and most of the other film manufacturers make two basic types of color film material. Most color film with 'chrome' in the name is color transparency film. That is, after( your film is processed it will normally be returned with the frames individually mounted as slides. The other kind of color film with '-color' in its name is color negative material. After pro- cessing, the film has a very deep orange mask, and the colors are seen as their complements; for example, red in the scene will appear as green on the negative. Hence, the only way to get a proper record of the scene is to have the negative proofed or printed. Both color films will pro- duce prints, just as both will produce slides. In addition, black and white prints can be made directly from color nega- tives treating the color nega- tives exactly as if they were black and white negatives. Slides, too, can be -made into black and white prints but an extra step is required. Because of the chemistry re-- quired to print from color nega- tive film, most color imperfec- tions can be corrected easily, but it is harder to manipulate color prints from color slides. Also, color negative materials are more forgiving about over- or underexposure, whereas color transparency films almost al- ways demand extremely accur- ate exposure. All color exposures should be accurate within half a stop to insure optimum results. If there is any doubt as to whether the exposure meter is functioning properly or your use of it is cor- rect, it is wise to shoot the same scene at different exposures to insure hitting the right one. In this case a good rule of thumb to remember is to oxerexpose color negatives and underexpose color transparencies. - Q. Although my foreground exposure seems correct in my color slides, the sky usually turns out a colorless white. Is there anything that can be done to retain the sky's blue and have the clouds show up more distinctly? A. Yes, the problem can be solved easily with a polarizing filter, which costs about $8-15 depending on make and filter size. Polarizing filters work sim- plest with a single lens reflex camera because you can se the effect of the filter directly through the lens. Not only will the filter cause the sky to retain it's blue hue, but it can also be used to screen out reflections from surfaces like store windows. polished wood cabinets, or water. Be- cause unwanted reflections are being screened out, the color emitted from the object will seem richer, more vivid. Polarizing filters are smokey gray in color and hence suitable for use with color as well as black and white film. They usu- ally necessitate an increase in exposure of about 1/ to 2 stops, depending on the make. If a red filter is used in ad- dition to the polarizing filter 1 ' when shooting black and white film, day can be transformed into night. If filter factors are used in getting the correct fore- ground exposure, everything will be normally recorded except for the blue sky which becomes almost black in the print. To get the most out of a po- larizer, the sky has to be ab- solutely clear, not overcast. The filter functions best when it is aimed 90 degrees to the light source. And because the filter can be rotated, it can act as a variable density filter for the sky, without altering the in- tensity of the foreground colors. * * * Q. What do you know about infrared film?-John D. A. It is available in most photo stores but until lately it has been a pain in the neck to get it processed. Kodak, which markets, Ektachrome Infrared Aero film in 20 exposure lengths in 35 mm cassettes will now accept the film for processing. They also have beefed up their black and white infrared film and it is now known as High Speed Infrared, with a speed increase of two stops compared to the old film. Kodak Ektachrome Infrared Aero film was originally pro- duced for camouflage detection by aerial photography. It has three image layers sensitized to green, red and infrared as op- posed to blue, green and red in ordinary color film. It records the visible spectrum in "false color." The only thing that is predictable is that healthy fo- liage appears bright red in color infrared film and snowy white in black and white infrared. It is a fascinating film to ex- periment with for those inclined towards odd-ball effects or a need to boast about using a film that most other protozraphers have not found a practical use for. Commercially it is used in areas ranging from camouflage detection to ecology and ar- chaeology. For further details consult Kodak's AppliedInfra- red Photography, two ,dollars at the photo stores. Q. What is the fastest color slide film available?-Ann B. A. How about Anscochrome 500? As the name implies, the ASA rating is a whopping 500. But don't expect fine grain! However, Kodak's Ekta- chrome-X and High Speed Ek- tachrome, respectively rated as ASA 64 and ASA 160 can be push processed, via paying an extra dollar for a Kodak ESP envelope, and given a higher speed rating of ASA 160 and ASA 400. What is "push processing?" It is the control exercised in developing to compensate for underexposures when shooting. When you underexpose at the camera, you're in effect assign- ing your film a higher speed rating than the manufacturer suggested necessary to obtain optimum quality results. A higher effective film speed can be obtained by using spe- cial speed compensating de- velopers for black and white film or extending the develop- ment time for both color and black and white films. But leaving the film in the soup for one hour instead of the recommended few minutes does not mean you will be able to rate your film at an astrono- mical ASA 1,000.000! Films can only be pushed so far before fog levels become too much of a factor,, or before grain becomes the size of golf balls ! Quadrupling the ASA rating (in effect pushing up by two f stops) should be about the limit to get negatives of printable quality. Push processing is available only for black and white films and commercially developed Ektachrome-X and High Speed Ektachrome in 35 mm or 120 size. It is not avail- able for Instamatic 126 cas- settes. It is also not available for color negative films. The high- DIAL 8-6416 MEET GINGER Her weapon is her body...

Kodak's Kodacolor-X, the film most commonly used by amateurs, is rated at ASA 80. But don't use Ektacolor CPS Professional film just to get the extra increase of ASA 20 if you intend to get Kodak processing. As it's name implies, it is meant to be processed and printed by color labs catering to profes- sionals. This doesn't imply that Ekta- color is of professional quality and Kodacolor can't deliver like results. The distinction that has caused this separation is the two shades of orange masking color.
