When taking interior photography, you will have to adjust your camera or use an accessory or two for good shots. Most types of photographic film and camera lenses are made for outside handheld use. When you take a camera indoors they usually aren't as effective because it's generally darker inside. This makes it harder to get a crisp, sharp image when you hold your camera inside. You can try to adjust the lens aperture to compensate for this and to get adequate depth of field, but you'll have to leave the shutter open longer to enable enough light to expose the film for a good image. It's hard to hold a camera steady during a long exposure, so you will have to use a tripod or light the scene with an electronic flash. Some subjects that make for interesting interior photos are interior gardens and courtyards, staircases, stained glass windows and patterned or painted ceilings. Most professional interior architectural photographers use medium format and large format cameras. You can experiment with various filters, lenses, lighting techniques and camera angles.
