You must have a memorable evening when you have the opportunity to admire and record super-moon images "beautiful crazy" for 70 years.

. the magnitude of the moon seems to overwhelm the massive architecture in Athens, Greece.

However, do you wonder why the author of the photo can capture such a big picture of the moon?

After all, the moon is high in the sky, and if you only look at the ground and watch the moon with your naked eyes, it is hard to see a big increase of 14% compared to the normal of the moon.

The truth that we often see is like this.

So which secret is behind the big picture of the moon? The answer is .

1. Apply perspective law

There is a fact that the pictures of the Moon taken at the end of the horizon, next to trees, tall buildings or massive structures . make you feel that the Moon seems bigger.

The moon phenomenon looks larger completely due to the mistake of the human brain.(Photo taken at Glastonbury, England).

In fact, photographers took advantage of optical illusions to make the Moon even bigger. And the Moon phenomenon looks bigger completely because of the mistake of the human brain.

The moon seems bigger at the end of the horizon .

. or next to the castle, but the castle is immense.

Ralph Weidner, a psychedelic German neurologist, said that because we and the Moon are separated by a great distance, we cannot feel the exact depth. The brain then calculates and determines that the object needs to be larger to fill the same space.

The left sphere looks bigger and is farther away from the right sphere, similar to the Moon at the horizon.

Therefore, the feeling of looking towards the horizon farther than the position at the top of many heads, this mechanism will fool the brain, making us see that the Moon is bigger than its real size.

2. Use photography tips

A beautiful photo will require the photographer to have a nice angle, good light. And a super moon picture with a big, round, bright moon will require the photographer to have a certain investment as well as patience.

Besides choosing a beautiful location - airy, fresh air, little dust, no artificial light, you need to choose a camera lens with a large focal length.

For cameras with small lenses (below 50mm) like smartphones, the Moon will look like a small ball in the frame due to the distance from the subject to reach the machine too far.

Therefore, in order to be able to capture the Moon in full size, the photographers often use cameras with lenses of 200mm or more . And to be more beautiful, you can choose a lens with a focal length of 500mm, 1000mm.

If using the crop body instead of full frame, the focal length will be multiplied by 1.5 times with the Nikon, 1.6 times with the canon.

Besides, you also need to consider the exposure for the image , - in the middle of about 1 - 4 minutes, aperture (aperture of the lens) f2.8. Depending on the height of the moon, the pollution of the light, the reflection of the landscape . the time of the moon day (night), which you adjust the exposure, the level accordingly.

Accordingly, the smaller the aperture (the smallest level is called f / stop), the larger the aperture of the lens should gain more light in the image.

Super moon is amazingly beautiful beside the Statue of Liberty in New York, USA.

But if you want to get a sharp image, you can choose a higher f-focal length like 5.6 or 8, combined with long exposure!

Typically, the aperture photographers use when taking pictures of the Moon is f / 11 for machines with a lens of about 200mm.

And with the combination of many tricks, photographers were able to create such super-beautiful, super-moon pictures!

There's a little tip for you, it's next December, you have a chance to admire the super moon too. Although the next time the moon is not big, beautiful "scrambled" like this time, but it is also an opportunity for you to show your talent, right?
