Q.

This winter I will be traveling to Yellowstone National Park to photograph wildlife in the snow. I would like to shoot closeups as well as distant shots.

In the past, my subjects have been underexposed.

What do you recommend for film speed, filters and metering? Do you have any other suggestions?

A.

First, I would take the following equipment:

Two camera bodies, at least one of which has a program mode; a 400mm telephoto; a 70-210 zoom, a 35-70 zoom and a 28mm wide angle. Also, a 2X tele-extender.

A polarizing filter that would fit at least two of the lenses.

A tripod heavy enough to support the telephoto lenses.

Very slow transparency film, such as Kodachrome 25 or Fujichrome 50, would be preferable. I would also take print film -- Agfa Color XRS 100 and 200, Fuji 100 and some Fuji 400.

For metering, I would trust my cameras' meters, but before I left I would have the cameras checked out and be confident that the meters were working well. I would also shoot some test rolls on the film.

With the equipment and film checked and properly bagged, I would concentrate on hiring a good guide. (To me, "wildlife" is a broad category. I would get advice on what to shoot.)

As for the underexposures, the best thing is to overexpose and bracket; one to two stops should be fine. Another way to compensate is to set your ISO rating down by one-half. (If you have 200 ISO film, set you camera for 100; if you're using 100 ISO film, set for 50, etc.) Q. I am a novice photographer and recently purchased some used darkroom equipment. I am unsure of the purpose and use of a Haynes MCM Photometer Model J. There were no instructions with this meter. Can you give me any help?

A.

This is turning into the search of the year. I have checked with people at the National Geographic Society, three other publications and three of the most astute photographic sales people in the area.

No one had heard of it.

Perhaps a reader has an answer.

Q.

I would like to find someone to make a simple photo collage for me. I'm interested in having a collection of snapshots trimmed around the edges, mounted on light press board, and covered with something less heavy than glass. Nothing fancy, I just want the photos on the wall where I can see them.

To have this done in a photo or frame shop would cost a fortune. Can you help?

A.

My immediate reaction would be to tell you to try it yourself. It would be all the more rewarding. But, if you insist you don't want to go this route, I suggest you do try some frame shops and see what they may charge or advise.

All that failing, let's see if any readers have any ideas.

The Charles Beseler Co. has started the neatest treasure hunt of the year. The company is searching for the oldest model 23C medium-format enlarger in existence. According to the manufacturer, the first model 23Cs were introduced in 1956. Thirty years later it has proved to be one of the most popular enlargers ever manufactured. The winner will receive a new Beseler 23 CII-XL enlarger system with a Dual-Dichro S color head and other accessories. It is a package worth over $1,300.

To enter, send proof of your enlarger's age such as a color photo and serial number to: Dept. BPM, Zachary and Front, Inc., 369 Lexington Ave., New York, NY 10017.
