God's Palette

Bamboo Bird slept well in the car, so now he can work quite quickly, but the model is not very cooperative.

"Don't move, let me tell you, oh, it's so annoying, Miss Ye, you can't do this, this concealer needs to be applied a lot, stop staring out the window, there will still be so many people staring, there will be no less."

"But I'm shy."

"You've been around the world, you've stood at so many manga shows, you've taken photos of so many dead houses, and you've been circulating sneaky photos of your panties, why are you so shy..."

"Those are safety pants, and, besides, these are two different things..."

"You're one of a kind."

Outside, the chatter of Xia Xun and Zhuanzhuan could occasionally escape through the window, and the photographer and assistants also had high expectations for photography.It can be heard that they are going around to learn scriptures, asking Xia Xun what equipment he plans to use, the model of the light reduction mirror, and so on.

"In this case, it is most appropriate to use a header, which is about a street away from the horizontal composition."

"What kind of exposure?"

"It's hard to say..." Xia Xun calculated and estimated the distance with pen and paper, as well as visual inspection, "I have to calculate first, the diffraction effect of your header at this distance and low light flux, How much will it affect the picture quality. This is the main factor that determines the expressiveness of the picture, and then you need to calculate the best aperture and calculate the depth of field..."

"Can it still be calculated?" Zhuan Zhuan barely knew the principles, but the actual operation was another level.

"It's just experience...it can't be said to be accurate..."

"Uh, anyway, it's time for my Invincible to play?"

"Well, turn it in. After you turn it in, take the lamp and beam accessories and go to the coffee shop opposite—see it."

Turning around and looking up at Xia Xun, I always feel that something is wrong. Could it be that it is not just their eldest lady who suffers?

Xia Xun pointed to a low brick house on the side of the street. The light and warm colors and green plants gave people a pleasing feeling.This is obviously a coffee shop opened by locals for tourists, exuding the unremitting pursuit of coffee that the Finns are proud of.When it comes to China, at least it is a super internet celebrity shop lined up for ten streets.

"Go to the second floor and open a window. Do you know the spotlights on the stage? When Ye Qian falls to the bottom, she will be ashamed, and you will be on the top to clearly illuminate her embarrassing appearance."

"Brother Xun... I would be ashamed in that way."

"After all, you are a member of the commune, so of course you need to help."

Inside the room, Ye Qianluo breathed a sigh of relief. Human beings are like this. No matter what they do is good or bad, as long as they are accompanied by someone, the burden will not be so heavy.Of course, in order to give herself—and the Ye family some dignity, Ye Qianluo asked Zhuniao to do another thing after putting on her makeup.

They got a wooden sign from a flea market by turning it over, gesticulating, and adding large denominations of euros.Relying on Google Translate, I wrote a few lines on it, depicting large characters in various languages.

"Please, don't look at me." Probably expressed such a meaning.

Unfortunately, this doesn't seem to work.

Chapter 139 The photography went well...

Optics—among the various sciences of mankind, is a subject that has not made long-term breakthroughs and progress for a long time.

Photography is the perfect use of optics.

However, no matter how many "algorithms" and "hardware" are created to pile up image quality based on human's digital attainments, there are still many places that are trapped by the stagnation of optics itself.

For example, the impact of diffraction on image quality is an inevitable contradiction between photosensitive elements with increasingly higher pixels and photographic image quality.Many laymen buy new high-resolution, expensive cameras, paired with often more expensive lenses, just to take pictures of travel landscapes.

And these laymen learned on the Internet that a small aperture is required to take landscape photos.

Although they don’t know what depth of field is or what post-processing is, they still followed the instructions on the Internet, narrowed the aperture to F16, and took landscape photos-then found that the quality of the photos was a mess...It’s better to buy a chrysanthemum brand , The fruit brand mobile phone should come well.

One of the big factors is the so-called diffraction effect.

For a high-resolution camera, once the aperture is narrowed, there is no special optimization or post-processing, but the image quality will be reduced. The sharpness, resolution, and strange light will be cast on the scene, which is caused by diffraction. The problem.This is also an unavoidable problem that Xia Xun has to face in terms of the subject matter that Xia Xun wants to shoot now.

The a7r3 has more than [-] million pixels. Although Sony has optimized the diffraction, it is just an optimization.

The problem still exists, although it is so subtle that laymen cannot see it, but it will poke Xia Xun's eyes very much.

Therefore, as an aspiring photographer, Xia Xun hopes to solve this problem as much as possible in the early stage of photography, instead of dragging it to the later stage to use a computer to deal with it.

It's not that she is opposed to post-production, but she just thinks that if she relies on her own skills, she can solve all kinds of problems during the photography process?That's a compliment to yourself.That small sense of accomplishment can make Xia Xun as happy as tasting candy for the first time.

"For F5.6..."

Xia Xun fumbled for the accessories in the backpack.

At the beginning, Mian Yu bought a bunch of brand-name accessories all at once, regardless of the size and purpose, she chose expensive ones anyway.Therefore, there are not many that can be used.Now Xia Xun needs a light reduction filter, because the amount of light transmission needs to be reduced and the exposure time should be prolonged to obtain the smear exposure effect.

In short, it is to wear sunglasses for the camera to block excess light.

She touched a light reduction filter, and the amount of light reduction was just right.

But there is still a problem.

Invincible is a movie lens. If the ordinary photography lens is a sparrow, then this thing is a hummingbird.If you want to put the light reduction lens for sparrows on hummingbirds, the caliber is wrong, no matter how tough you are, it will not be able to screw it on.

Xia Xun thought it was troublesome, so she didn't want to hold the light reducing mirror with her hands. After pondering for a while, after saying hello to Zhuniao, she dug out a selfie stick from her luggage... She obviously slept soundly all the way, this one The selfie stick is woefully useless.

However, the selfie stick clamped around the filter, and then wrapped several times with a rope to tie the selfie stick to the tripod.On the camera stand, adjust it a little bit, and then use the rubber band that the girl tied her hair to tie the protruding part of the selfie stick to the wrist strap of the camera. The local method filter is successfully tied.

Thanks to this girl who has a car, if you want to change it before, it is impossible to find a rubber band.

In any case, the ND filter was successfully fixed in front of the lens, and it was still usable.

Carrying the eye-catching camera, she went across the street, looking for a suitable camera position amidst the attention of people coming and going.Through shooting again and again, recalculating the exposure and depth of field, deciding where to embarrass Ye Qianluo and where to light up Zhuanzhuan...

The photographer was ready, and no matter how shy the model was, she finally showed up.

Ye Qianluo——no, Spiral Organ, Lian Nanxi, has changed her human body and turned into a stiff two-dimensional figure as if she just popped out of a stone, coweringly hiding at the intersection, life and death I dare not take another step into the crowd.
