Where can I buy photographic insects?

——————— Let me talk about digital macro first:

Macro is a very hot topic in the field of digital cameras.

To take macro photos, you must first have a macro lens, which is a lens that can focus very close to the subject. The size of the image formed by the macro lens on the film is almost equal to the real size of the subject itself.

The relationship between the size of the image on the film and the size of the object is called the copy ratio. 1: 1 indicates that the image on the film is the same as the real thing, 1:2 indicates that the image on the film is half the size of the real thing, 1/3 indicates that the image is the real thing, and so on.

Different manufacturers use different standards to name their macro lenses, which causes some confusion. Generally speaking, we think the following terms are more appropriate.

Macro lens refers to a lens with a copy ratio of about 1: 1.

Macro focusing lens refers to the lens with the reproduction ratio of 1: 1.2- 1:2.

A near-focus lens refers to a lens with a reproduction ratio of 1:2- 1:4.

Although the macro lens is usually a lens with a medium focal length, it can actually be a lens with any focal length, including a 50mm macro lens, a 100mm macro lens or a 70- 180mm macro zoom lens. Giving the lens a macro name can only show that the lens can focus on the subject closer than the ordinary lens.

Macro lens is very valuable for shooting small objects, such as insects, flowers, stamps and so on.

Wild stamens shot with a macro lens look like the photo above. The photo was taken with a macro lens, and the stamens looked like wonderful abstract patterns. The trick of taking macro photos is to focus accurately; Because the clear focus range of macro photos is very small, only a small part of 1 inch. For example, to take macro images of bees on flowers, it is necessary to ensure that bees focus accurately and clearly; Suppose that the distance from the lens to the bee changes even if it is less than 1 cm, and the clear focus will be lost. Therefore, in the process of taking wonderful macro photos, focusing is extremely torturous. How to focus accurately will be introduced later.
