Architectural and interior photography require a keen eye for detail, understanding of light, and ability to showcase the feel of a space. Here are some tips:

1. Use a Wide-Angle Lens: A wide-angle lens can capture more of the space and give a sense of depth and dimension.
2. Pay Attention to Lines: Vertical and horizontal lines should be straight. Use the camera's gridlines to help align these lines, and you can also correct distortions in post-processing.
3. Lighting: For interiors, try to use natural light if possible. Turn on all lights to give the room a warm and inviting feel.
4. Composition: Use the rule of thirds, leading lines, and frames within frames to guide your composition. Try to include some context or surroundings in architectural shots.
5. Time of Day: For exteriors, the golden hour or blue hour often provide the most flattering light.
6. Post-processing: Correct distortions, enhance colors and contrast, and brighten shadows in post-processing.

Remember, architectural and interior photography is not just about documenting a space, but telling its story and showcasing its character.
