杜絕不良習慣可從源頭著手，亦是比較可靠。減少接觸導致壞習慣的提示是消除壞習慣最實際的方法之一。

例如，如果您似乎無法完成任何工作，您可以將手機放在另一個房間幾個小時。

A more reliable approach is to cut bad habits off at the source. One of the most practical ways to eliminate a bad habit is to reduce exposure to the cue that causes it.

For instance, you can leave your phone in another room for a few hours if you cannot seem to get any work done.

Macro Photography

Extension tubes, a tripod, a flash or a remote shutter release can be used in macro photography rather than dedicated macro lenses and other expensive equipments.

Extension tube

With any lens, the longer the extension tube, the greater the close-up effect. The 12mm EF 12 II is often used with wide-angle lenses, while the longer EF 25 II is a better choice for normal or telephoto lenses. Auto exposure continues to work reliably, but manual focus is recommended in most instances.

A wide-angle lens has a focal length of 35mm or shorter, which gives you a wide field of view.

There will be some light loss when we use extension tube and it will make the shutter speed get slower and the ISO gets higher. Do not hesitate to increase the ISO to get wider opening of the aperture and narrow depth of field. But it will be a different case altogether if the subject is still. You will need a tripod that will be very useful to drag the shutter speed and lowers the ISO. The best way of using extension tube is to set manual focus.

Extension tubes do not affect the image quality or the light transmission of your lens, and they are relatively inexpensive to buy. However, they also reduce the depth of field and the focusing range of your lens, so you may need to use a smaller aperture and a tripod to get sharp images

Lens specification

EF-S 18-55mm f/3.5-5.6 IS II

Electro-Focus Short back focus means the lens has a shorter distance between the rear element and the sensor than regular EF lenses.

Largest aperture is f/3.5 at the 18mm focal length.

Largest aperture is f/5.6 at the 55mm focal length.

The image stabilization system can reduce camera shake by up to four stops, allowing for sharper handheld shots in low light conditions.

The II version has a slightly better image quality, especially at the wide end, with less distortion, chromatic aberration (色差), and vignetting.

Vignetting: 周邊暗角: 底片上曝光的光度，由中央到角落有減弱的情形，造成四周較暗的現象，可能是鏡頭造成之自然表現，或不當使用遮光罩或濾鏡造成。

Will AI Machine develop love?

Some researchers argue that AI systems are unlikely to exhibit human emotions like love or hate, and that there is no reason to expect AI to become intentionally benevolent (仁慈的) or malevolent (有惡意的). Others suggest that AI systems may develop some form of emotional attachment or bond with humans, as shown in some fictional scenarios such as the film Her.

Ultimately, the question of whether AI machines will develop their own emotions like love in the future depends on many factors, such as the definition and measurement of emotions, the design and purpose of AI systems, the ethical and social implications of emotional AI, and the evolution and innovation of AI technology.

Love in Interstellar

The film reveals a powerful insight to human relationships and how our love for one another transcends physical reality. The story reveals that love is not just an emotion, but rather a powerful, dynamic, and driving force within and even beyond the cosmos. Love is the one thing we’re capable of perceiving that transcends dimensions of time and space, as Dr. Amelia Brand says in the film. Love is also what connects Cooper and Murph across the vast distances and allows them to communicate through the fifth dimension, which is a physical manifestation of Cooper’s love. Love is what enables Cooper to sacrifice himself for the sake of humanity and his daughter, and what motivates Murph to solve the equation that saves mankind. Love is what conquers all emotions and challenges in the film.
