Q - Recently you give instructions about taking sunset pictures. Can the same techniques be used for a sunrise?

A - Yes. Basically, you're dealing with a similar photo interpretation, which is to accentuate the sky colors. To do this, take your meter reading from a bright area of the sky but not directly from the sun. Added drama can be given both sunset and sunrise scenes by underexposing by a stop and by including an interesting silhouette of the landscape such as trees, a house or a barn or, in seascapes, a boat or rocky shoreline. Use a skylight filter to warm up the colors.

Q - My cousin is getting married and I want to take some photos of my own, even thought they will have a wedding photographer. Can you give me any tips?

A - My first tip is not to get in front of the official photographer. He's trying to make a living - and the bride won't like it, either if he misses some shots because you're in the way. But you don't need to get in the way, especially if you're prepared.

Start by loading with the new ASA 400 color negative firm. Your prints will be better than from transparency film and it will cost less. Besides, the added speed will let you take candids in dim light.

Your first photo opportunity will come inside the church as the bride and groom walk up the center aisle. Get an aisle seat about midway to the altar. Set your camera by prefocusing on a guest in another aisle seat right where you will want to catch the procession. Then shoot with flash when they walk up the focused spot. You can do the same thing when they return from the altar. Flash is best for these because of the movement.

During the ceremony you can take some candid natural-light shots of the interior, if you've made special arrangements, of the ceremony from the side, up front.

Your next chance comes when the bride and groom leave the church amide the flying rice. For this, move back far enough to include the line-up of rice throwers and again be ready for the action by prefocusing on the waiting guests. If the light is good, you'll be able to shoot this without flash with the fast film - if not, use your flash.

Your next target, is the getaway car. You'll have to run for this one. You'll have two chances here, as the bride and groom get in the car and as it pulls away.

Q - Is it true that the lower ASA on 35-mm slide film, the better the sharpness and quality of the enlarged print?

A - Absolutely. That's why National Geographic staffers shoot Kodachrome. The slower films are harder to shoot, but the difference in results is worthwhile. I've had 35mm Kodachrome transparencies made into prints more than six feet wide, which at the proper viewing distance look dead sharp. The slow-film preference also gives for black-and-white.
