Lunar photography course

Lead: Although many people like to shoot the moon, they are not allowed to shoot the essentials of the moon, and the photos taken are not ideal. When it comes to shooting the moon, many novices will complain, why is the moon I shot like a pie? No details! Indeed, it takes some skill to photograph the moon. If you are not careful, it will be made into a white cake!

The beauty of taking pictures of the moon lies in taking pictures of veins, craters and shadows on the moon. What is the name of the moon? Ball? Because it has three-dimensional effect.

The first thing to pay attention to when shooting the moon is exposure. If you use the average metering of the camera, most of them will be overexposed. This is because the overall light brightness is not enough, and the metering system increases the exposure. In order to achieve accurate exposure, we can use the following methods:

The first is to set the correct aperture. You can't shoot the moon with the default maximum aperture (F2.8 or F2.0) of many cameras. Generally speaking, an aperture of F5.6 or above should be used. So far, there is one? Sixteen rules of sunshine? This theory can be used for reference not only for aperture but also for shutter. (See note)

The second is to use spot metering to measure the brightest part of the moon. In this way, the correct exposure coefficient can be obtained as much as possible.

Attention:? Sunshine 16 law? The English name is Sunny 16 Rule. It is an ancient method to decide what kind of aperture and shutter speed should be chosen when shooting outdoors. According to this law, the shutter speed is set to the nearest reciprocal of the sensitivity used in the film. For example, if ISO200 is used, the shutter is set to 1/250 seconds. As for the aperture, when the scorching sun is in the sky, that is, when you can determine the position of the sun in the sky, use f/ 16, and when the position of the sun is uncertain, use f/1; When the sun is covered by clouds, use f/8; Use f/5.6 when the sky is cloudy or the main body is in shadow. Although this method is primitive, it is very effective and will definitely shoot the scenery. In fact, since ancient times, plastic roll manufacturers have expressed this rule with pictures and printed it on the inner layer of cartons for reference.

? Sunshine 16 law? It's a set of rules that photographers summed up based on their own experience a long time ago. As this is only personal experience, there are naturally some inaccuracies or inaccuracies. In fact, there are many people on the Internet who have had a lot of arguments about the correctness of his theory. This rule is aimed at traditional cameras. You can learn from this rule when shooting, but you don't have to be too serious.

The third is exposure compensation. When shooting the moon, you usually need to reduce the exposure. Generally, you should reduce 1 or 2, depending on the situation when you shoot. Shoot according to different aperture and EV values, play back immediately, and adjust according to the results before shooting. These are easy to realize in digital cameras, which greatly improves the success rate of shooting.

Secondly, consider the shutter speed. Follow? Sixteen laws of sunshine? Generally speaking, if the shutter is set around F5.6, the shutter speed should be set at1125 seconds or faster. In addition to preventing overexposure, there is another important reason for using high-speed shutter, that is, the moon, as a celestial body, is constantly moving. If the shutter speed is too slow, it is easy to paste. Nothing is absolute. Some people shoot the moon more clearly with a slower shutter speed. This is all related to the weather at that time and the equipment used. )

Finally, the choice of ISO sensitivity and zoom. Generally speaking, the lowest sensitivity for shooting the moon can be either ISO 50 or ISO 100. Too high ISO will not only cause overexposure, but also make the picture rough.

As for the focal length of the lens, the longer the better. There is a simple reason. The longer the zoom lens, the bigger the moon. However, it should be noted that the longer the focal length, the easier it is to be burned by hand shaking. So it's best to shoot the moon with a tripod.

In order to shoot the moon better, many astronomy enthusiasts DIY many astronomical telescopes and install them on digital cameras, and the photos taken are also very good. However, it should be noted that the use of high-power zoom also has disadvantages, that is, the greater the zoom dispersion, the more serious the situation. Especially the modified cheap high-powered telescope.

The above skills are aimed at all manual cameras, and those stupid cameras without shutter and aperture adjustment may have some difficulties if they want to shoot the moon. Take the Fuji S304 I used. This DC has only aperture priority and no shutter priority function. So there is no way to distinguish the shutter when shooting the moon. At this time, the shutter speed can be improved by turning on the flash, which is also an effective remedy. At the same time, lowering the EV value can also improve the shutter speed to some extent.

Before turning on the flash.

Turn on the flash.

Last but not least, photographing the moon usually takes place on a sunny night, and it is better to have no clouds in the sky. Under such high visibility, the moon will naturally be clearer. To tell the truth, the ordinary digital camera we use can only be regarded as shooting the moon. For friends who are keen on shooting celestial bodies, it may be very rewarding to search some special astronomy enthusiasts' websites on the Internet.

Theoretically, it is to shoot a simple moon. Let's talk about how to take a night picture with the moon in it. This photo of the moon usually only plays an embellishment role in the picture. If you shoot according to the above data, the scenery on the ground will basically be underexposed. So pay attention to the exposure balance between scenes. In the traditional field, photographers like to take multiple exposed photos. Some digital cameras don't have the function of multiple exposure, but don't forget that computers are very capable! Many difficult shots can be solved by computer.

This time we will use PHOTOSHOP to help. First take a night view, then take a big moon with a telephoto lens, and superimpose the moon on the original night view with a computer to become an extraordinary night view photo of the big moon. Of course, not all moonlit scenes have to take a big picture of the moon. For example, a small crescent moon will bring unexpected artistic conception to the picture.

Another problem to pay attention to when shooting the moon is: don't expose it for too long. Because the moon revolves around the earth, the relative position of the moon has changed with the passage of time, so we may not get a clear image of the moon in the photo, but an ellipse, and a longer exposure time will get the trajectory of the moon. If you want to expose for a long time, you'd better use a stereograph.
