What does macro mean?

Question 1: What does a macro lens mean? It is a lens designed for close-range photography, which can take images with double or equal magnification. Due to special design and correction, its resolution is higher than that of ordinary lens. Because its lens barrel is longer than ordinary lens, it needs compensation when exposed. Its depth of field is short, so you should use a small aperture when shooting thick objects.

Question 2: What does macro mean on a digital camera? 1CM refers to the nearest focal length. Please don't pull the longest focal length when shooting macro. After pressing the macro button, a macro fine-tuning prompt box will appear, and the focus range can only be adjusted in the prompt box. Please move the camera and fine-tune the macro to focus and take photos ~, and you can ask me if you don't understand. Thank you!

Question 3: What does macro mean in digital camera parameters? Under normal circumstances, when the subject is too close, such as 5 cm, the general camera will lose focus.

If you choose macro mode at this time, you can easily concentrate on shooting.

Note: When selecting this mode, be sure to keep the phase steady, otherwise the film will be blurred easily.

Suggestion: When using macro mode, use a tripod or put the camera on the table to shoot.

I hope the landlord can make full use of this practical function.

Question 4: What is macro photography? It means taking pictures very close to the object. The requirement is that the camera must support this macro function.

Question 5: What does the macro of digital camera mean? Friends with digital cameras often take pictures of small objects around them, and for people like us who deal with computer products all day, taking pictures of products is even more common. How to shoot these small objects? How to show the details of our products? NULL Today we are going to talk about macro shooting with digital cameras.

First of all, let's clarify the concept of macro: how far is it for macro to shoot NULL? For most digital cameras, 50cm is usually the dividing line between macro mode and normal mode, so we count less than 50cm as macro. If it is more standardized, we should use the concept of magnification. If the height of the subject is X and the imaging height on the negative (or CCD or CMOS) is Y, then the magnification is equal to Y: X, and usually the smaller numerator or denominator is reduced to 1. For example,1:5,2:1and so on. The magnification that a digital camera can achieve is between 1: 1 to 1: 10, which belongs to the range of near macro photography.

To take a good macro photo, you need to pay attention to the following aspects:

1. Choose a digital camera with strong close-up ability. In the specification table of digital camera products, "the nearest shooting distance" is a very important indicator, and the manufacturer will give a number, such as 10cm, 6cm or even 2cm. So, is the nearest shooting distance as short as possible? NULL6cm is definitely better than 10cm. NULL is not necessarily. In addition to the number of the recent shooting distance itself, we also need to pay attention to which focal length range this recent shooting distance has reached. For example, a digital camera can achieve close-range shooting of 6cm at the wide-angle end, zoom to the telephoto end, and the recent shooting distance is more than 20cm; Digital camera B has a 7-fold optical zoom, and the nearest shooting distance is 13cm, but it achieves the longest focal length (that is, 7-fold zoom). In this way, the magnification of digital camera B is much larger than that of digital camera A. It can be seen that the recent shooting distance of digital camera changes with the change of camera focal length. After the focal length of most cameras is lengthened, the recent shooting distance is greatly increased. For example, Sony F707 can shoot 2cm at the wide-angle end, but after zooming to 5 times, it can only shoot objects 90cm away. However, there are a few exceptions, such as Minolta's Dimage7, and 7 times zoom can achieve the maximum magnification of the telephoto end.

At present, the close-up ability of common digital cameras can be roughly divided into three levels:

① Nikon COOLPIX series, Sony F505VkF707, CasioQV2800ux/2900ux, Minolta D5/D7, Ricoh RRl, etc. Most of these products can achieve a close-up of about 2cm, or a wide-angle close-up with a magnification equivalent to 2cm.

② Casio QV3000EX Qv4000, Canon GL/G2, KodakDX3900/DX4900, etc. Most of these products have a recent shooting distance of 5- 10cm, and their close-up ability is medium.

③ Canon S series /A series, Fuji Finepix series, Kodak DC series /DX series and other models, and most models such as Olympus and SONYP series. The recent shooting distance of these products is mostly above 10cm, which can't cope with smaller subjects.

2. When shooting, if the camera allows, you can choose the telephoto end to shoot at a distance.

Although the shooting distance of 2cm is attractive, it is not so convenient to use. Pushing the object to be photographed so close to the lens is inconvenient to place (especially after using a tripod), and it is easy to accidentally hit the lens, and there is no way to arrange the lights. In addition, if you are so close to the camera, the captured image will be greatly distorted. You might as well take a step back and shoot with a longer focal length at a distance of about 10cm, provided that your camera allows it.

3. You can use a smaller aperture appropriately.

If you have to shoot at the wide-angle end and use a very close shooting distance, the spherical aberration (that is, the imaging error caused by the difference between the center and outer edge of the spherical lens and the subject) will be obvious. At this time, you should give up the large aperture like F2.0 and shoot with F5.6 or even F8.0, which can reduce the spherical aberration and increase the depth of field.

4. Try using a tripod and * * *

Question 6: What do you mean by taking macro photos with your mobile phone? Mobile macro photography means that when a mobile phone needs to shoot a close-up object, it will focus on the center of the object closest to the lens with a macro when the focus is not accurate, so that the details of the object are more prominent and the photographed part is the clearest. It is often used when shooting small objects, such as words.

Question 7: What is super macro? In fact, strictly speaking, there is no recognized division between "macro" and "super-macro" rhetoric. But generally speaking, the closest focusing distance of the wide-angle end of the camera is 1cm, which can basically be called "super macro".

As for SLR cameras, it is recommended to buy a special macro lens if there is demand. If you just want to play, the flowers and insects shot by the general lens should meet the needs. ...

Question 8: What does macro mean in a digital camera? In macro mode, the closest focus distance is 3.5MM, and the closer the distance is, it means that you can shoot a 3.5MM object recently. The calculation of 3.5MM may start with a short lens or CMOS.

Question 9: What does macro lens 1: 2 mean? Take Quan Huafu CMOS as an example, 1: 1, that is to say, a 3.6×2.4cm rectangular object can be photographed by CMOS at the maximum;

But 1: 2 won't work, and the magnification is only 0.5.
