These three elements are the foundation of photography, often called the “exposure triangle.” If you understand how they interact to control light, depth of field, and motion blur, you’ll move beyond automatic settings and gain the power to create exactly the image you envision, rather than just capturing what’s there. Dust, smudges, and fingerprints on my lens or sensor can significantly degrade the quality of your photos, leading to blurry spots or hazy images. A little regular care with appropriate cleaning tools will ensure I always deliver crisp, clear results.
