Q. Two questions: First, I took a roll of film at an important event. The film was either 100 or 400 speed 35mm film. It was returned to me, with a note from the developer that the film was exposed and no pictures could be developed.

The negatives have very faint outlines of subjects on them. Is there a special process that would allow for the pictures from these negatives to be developed?

Second, I have just invested in a 35-200mm zoom lens for my Pentax K1000. As a novice, how should I introduce myself to the use of this camera lens? (I don't want to just take pictures of flower blooms.)

A. In answer to your processing problem: I'm afraid you probably won't be able to get any successful prints. It sounds as if the film was exposed to light and mostly fogged. Without having seen those negatives, I can't be absolutely sure.

There are some things to try, but they can be time-consuming and expensive. Try taking the negatives to a custom printing lab. (There are several listed in the phone book, or ask at one of the camera stores in the area). Call Eastman Kodak at its consumer product information line, 800/242-2424, and see if you can get any information.

Try calling someone in your local camera club; almost all of them have people who do custom printing and may be able to help.

If all this fails, bite your lip and go on to take more pictures, the way the rest of us do when we screw up a roll of film.

As far as your new lens goes, don't be impatient. Learning how to use a new lens, especially one as sophisticated as yours, is a slow, careful process.

I have found the best way to start is to zoom your lens all the way back to the 35mm position and leave it there for a while. Begin by playing "Let's Pretend." Leave the film out of your camera and practice. Make "pictures" of people, houses, pets and even your office and the people there. Learn how to squeese the exposure button and hold the camera still as a rock. Practice making slow exposure pictures as well as super- speed outdoor shots. Remember, don't zoom the lens

When you feel comfortable and automatic, load the camera and do the same things for real. As you shoot, be sure that you write down what you shoot on each frame and what exposure you use. If you are on automatic, write that down. When you get your pictures back, you can judge what has worked and what hasn't.

Then try doing the same thing with the lens zoomed all the way out to 200. Try to make the same pictures you did with the lens zoomed back to 35mm. Compare the results and then start trying the lens at mid- zoom. By the time you've shot four or five rolls, you should have few problems. METER MALFUNCTION

Q. I have a Pentax K1000. Under low light situations the light meter needle first indicates that there isn't enough light, then slowly rises to the center, falsely indicating enough light. I can then change the aperture from 2 to 22 and/or the shutter from 1 to 1,000 and the needle stays right there. Am I doing something wrong or is there something wrong with the camera?

A. I spoke with a technical representative at Pentax and we agreed that you aren't doing anything wrong and that needle should be moving.

We also agreed that first you should change the batteries in that camera. A year or so ago I had a similar problem with one of my Canons and new batteries fixed it up. The Pentax representative told me that you want two Eveready A-76s. When you change the batteries, be sure to clean the contacts and the battery holder with a cotton swab mositened with alcohol. This may help.

Check your owner's manual before you make the change and be sure you're doing it correctly.

If new batteries don't do the trick, and you bought the camera from a reputable camera store, take it back and discuss it with your salesperson, especially if the camera is still under warranty.

If that still doesn't work, the Pentax representative suggested that you send the camera to the Pentax Service Center, 1101 Stewart Ave., Garden City, N.Y. 11530. However, before you ship anything, I suggest you call them at 516/222-0830. WILDLIFE PHOTOGRAPHY
