Final answer:
Tight lens photography is utilized to focus attention on the main subject and eliminate distractions from the surrounding environment, which works by zooming in on the subject. This technique is effective when the camera can properly auto-focus; otherwise, the image may turn out blurry. It also relates to the basic principles of camera focusing, where lens distance needs to be adjusted for clear imaging of various object distances.
Step-by-step explanation:
When to Use Tight Lens Photography
Tight lens photography is often used to clear up distracting backgrounds and focus on a specific subject. For instance, in a scene cluttered with objects like bleachers, poles, and trees, using tight lens technique by zooming in or using a longer focal length lens will aid in minimizing distractions and emphasizing the subject. It is crucial to ensure that your digital camera can focus when using such techniques. Pressing the shutter button halfway allows the camera to auto-focus and indicate whether you are too close to the subject for the lens to capture a sharp image.
Other Aspects of Photography to Consider
Concerning other related camera settings, it's important to know when to adjust shutter speed and aperture. A slower shutter speed is typically used in low light conditions or to capture motion blur, while a faster shutter speed freezes motion. Moreover, the depth of field is influenced by the aperture size: a wide-open aperture results in a shallow depth of field, isolating the subject from the background, whereas a small aperture provides a greater depth of field, bringing more of the scene into focus.
The ability to focus on both near and distant objects is not possible with a fixed lens-to-sensor (or film) distance due to the nature of thin lenses, which requires adjusting the lens's distance to focus light correctly onto the sensor or film for clear images. This represents the fundamental principle behind focusing in cameras, whether it is a smartphone camera or a standard optical microscope.
