L'objectif fisheye est un objectif grand angle doté d'une conception optique spéciale, qui peut présenter un grand angle de champ de vision et un effet de distorsion, et peut capturer un champ de vision extrêmement large. Dans cet article, we will learn about the characteristics, applications, and usage techniques of fisheye lenses together.

1.The characteristics of fisheye lenses

1) Strong distortion effect

Compared to other lenses, fisheye lenses have a stronger distortion effect, causing straight lines in the image to appear curved or bent, presenting a unique and fantastical image effect.

2)A broader perspective

The perspective of fisheye lenses is usually between 120 et 180 degrés, and compared to other wide-angle lenses, fisheye lenses can capture a wider range of scenes.

3)High transmittance

haute résolution, fisheye lenses have a higher transmittance and can achieve better image quality under low light conditions.

2.The application of fisheye lenses

1)Create unique visual effects

The distortion effect of fisheye lenses can create unique visual effects and is widely used in artistic and creative photography. La perception visuelle D peut également être utilisée pour l'évaluation sportive grâce à la reconnaissance et au positionnement de corps et d'objets humains en mouvement rapide, taking photos of buildings, landscapes, people, etc. can present images in a unique form.

2)Sports and Sports Photography

Fish eye lenses are suitable for capturing moving scenes, presenting a sense of dynamism and enhancing the impact of motion. Commonly used in fields such as extreme sports and racing cars.

3)Shooting Narrow Spaces

Due to its ability to capture a wide field of view, fisheye lenses are often used to capture narrow spaces such as indoor, car, cave, and other scenes.

4)Outstanding perspective effect

The fisheye lens can highlight the perspective effect of close-up, close-up, and close-up, creating a visual effect of foreground enlargement and background reduction, enhancing the three-dimensional sense of photos.

5)Advertising and commercial photography

Fish eye lenses are also widely used in advertising and commercial photography, which can add unique expressive and visual impact to products or scenes.

3.Tips for using fisheye lenses

The special effects of fisheye lenses have different application methods in different shooting themes, and need to be tried and practiced according to actual situations. Overall, the use of fisheye lenses requires attention to the following techniques:

1)Using distortion effects for creation

The distortion effect of fisheye lenses can be used to create a curved or exaggerated distortion of the scenery, enhancing the artistic effect of the image. It can be used to shoot buildings, landscapes, people, etc., highlighting their unique forms.

2)Try to avoid the central theme as much as possible

Due to the significant distortion effect of fisheye lenses, the central theme is easily stretched or distorted. Therefore, when composing, the focus can be on edges or irregular objects to create a unique visual effect.

3)Pay attention to reasonable control of lighting

Due to the wide-angle characteristics of fisheye lenses, it is easy to experience overexposure of light or heavy shadows. To avoid this situation, it is possible to balance the exposure effect by adjusting the exposure parameters reasonably or using filters.

4)Reasonable use of perspective effects

The fisheye lens can highlight the perspective effect of near, big, far, and small, creating a visual effect of foreground enlargement and background reduction. You can choose the appropriate angle and distance during shooting to highlight the perspective effect.

5)Pay attention to the distortion at the edges of the lens

The distortion effect of the center and edge of the lens is different. When shooting, it is necessary to pay attention to whether the image at the edge of the lens meets the expectations, and make reasonable use of edge distortion to enhance the overall effect of the photo.
