OF ALL THE FACTORS THAT INFLUENCE THE AUTHENTICITY OF AI IMAGES, LIGHT IS THE MOST VULNERABLE TO EXPOSURE<\/p>\n

Pictures, materials, details can be fixed by models, but not by light<\/p>\n

Once the light is not natural, a high-resolution map will also look \"false\" -<\/p>\n

LIKE A STICKER, LIKE A PLANE, LIKE A P<\/p>\n

Why?<\/p>\n

Because it's the logic of space<\/p>\n

It determines the size, depth, emotion, rhythm of the object<\/p>\n

CAN YOU GET AI TO CREATE A \"PHOTOGRAPHIC SENSE\" IN ESSENCE, DEPENDING ON WHETHER YOU CAN WRITE A LOGICAL LIGHT<\/p>\n

and control of the light is not possible by the vague word \"cinematic lighting.\"<\/p>\n

FOR AI TO UNDERSTAND LIGHT, IT MUST BE GIVEN THREE MESSAGES:<\/p>\n

Direction, light ratio, color temperature\u3002<\/p>\n

The light's direction: determined the stereotic sense and narrative logic<\/p>\n

Why is the light spirit in the direction<\/strong><\/p>\n

In the history of photography, most of all, the \"directive light\" is the Rembrandt light<\/p>\n

In the 17th century, Rembrandt, a Dutch painter, used to use the light above 45 degrees in portraits, causing a typical \"small triangle shadow\" to appear in his face, which later became the golden rule of the photo studio<\/p>\n

\"671f2473j00tl6qkz002nd000fi006ip\"<\/p>\n

You probably didn't notice:<\/p>\n

We know that the reason for the stereo is not because of the size, but because the light is on the surface, and when the light comes in from the side, the shadows come in, the dark line is formed, the object is \"stand up,\" so the direction is not just aesthetic, but the syntax of space<\/p>\n

AI WHY DOES NOT UNDERSTAND THE \u201cDIRECTION\u201d<\/strong><\/p>\n

The AI model doesn't understand the physical world when you write \"cinematic lighting,\" it doesn't understand \"light coming in through the window,\" it just makes the whole picture dim or adds random light<\/p>\n

\"i'll<\/p>\n

(presentary with a cainematic lighting)<\/p>\n

As a result:<\/p>\n

Everything's bright, there's no shadow, the picture is flat, the body is floating<\/p>\n

YOU HAVE TO LET AI \"SEE\" THE PATH OF LIGHT\u3002<\/p>\n

It's written from a physical logic and tells it where the light comes from, where it hits, what it results<\/p>\n

Error:<\/p>\n

it's not like you're in trouble<\/p>\n

Correct:<\/p>\n

soft sunlight entering from the right window, lighting the subject's face, standing long shadows on the table<\/p>\n

\"c0d6eb0ej00tl6qmz00i2d000no00hrp\"<\/p>\n

You see, three more key messages:<\/p>\n

orientation (froom right), subject's face, shadow results (long shadows)<\/p>\n

THAT'S THE THREE ELEMENTS OF AI'S UNDERSTANDING OF SPACE LOGIC<\/p>\n

Photographic principles: main and auxiliary light<\/strong><\/p>\n

In the light, any lamp has a role<\/p>\n

Key Light shapes, Fill Light balance shadow, Backlight split contour<\/p>\n

AI, YOU'RE ACTUALLY IN THE LIGHT<\/p>\n

You can say that:<\/p>\n

(subject) lit by warm key light from the right, soft fill light from the left<\/p>\n

THAT'S HOW IT'S DONE. IT'S GOT THE MAIN, THE SPACE, THE SIZE\u3002<\/p>\n

Light ratio: Control the depth of the image and visual rhythm<\/strong><\/p>\n

1. What's light<\/strong><\/p>\n

Lighting Ratio means the brightness of the brightness and the darkness of the picture, which is one of the core concepts of photography<\/p>\n

\"b6c55de8j00tl6qog009hd000i000fbp\"<\/p>\n

An example:<\/p>\n

The United States suburbs series filmed by photographer Gregory Crewdson has almost every very strong contrast of light \u2014 the sun outside the window, the lights in the room, the depth of the shadows, which together form the tension of narrative\u3002<\/p>\n

\"486b85bdj00tl6qos00rld000td00erp\"<\/p>\n

He never pursued the \"average brightness\" but let the light tell the story<\/p>\n

2. How to control the light ratio in the hint<\/strong><\/p>\n

AI MODEL LEANS TOWARDS \"BRIGHT AVERAGE\"<\/p>\n

BECAUSE MOST OF THE IMAGES IN THE TRAINING DATA ARE RAISED AT AN ADVANCED STAGE OF EXPOSURE, WHICH ALLOWS AI TO \"FEAR SHADOWS\" WHEN THEY ARE GENERATED, IT PREFERS TO BE BRIGHT AND NOT TO BE DARK, BUT IN REAL PHOTOGRAPHY, SHADOWS ARE THE BASIS OF SPACE\u3002<\/p>\n

Because, uh, the contrast is the source of depth<\/p>\n

IF YOU WANT TO HAVE A HIERARCHY, YOU HAVE TO TELL AI CLEARLY:<\/p>\n

Where's the bright face<\/p>\n

Where's the dark side<\/p>\n

Whether it's mutation or evolution between the bright and dark<\/p>\n

For example:
\na man standing under a first light, face illuminated brightly, backgrounding into shadow, long contrast pitio, smooth light falloff<\/p>\n

\"11b356c6j00tl6q4007d000s7000aop\"<\/p>\n

AI WILL UNDERSTAND THE \"SUBJECT BRIGHTNESS, BACKGROUND DARKNESS\" STRUCTURE OF THE MAIN LIGHT\u3002<\/p>\n

High light, the view of the audience will be directed to the light; low light, the attention will be evenly distributed<\/p>\n

So it's not only true, it's not true<\/p>\n

In a hint you can write:
\non the face, dark background, dark on left side<\/p>\n

it's more useful than any \"highness lighting\"<\/p>\n

Colour Temperature: Light's Emotion and Time Logic<\/strong><\/p>\n

1. Why does a photographer care about color temperature<\/p>\n

The photographer Edward Hopper used to use two types of light in his paintings and photographs: cold light to be lonely and warm light to be calm. That's the color-hot narrative\u3002<\/p>\n

Cold, cold, blue, warm, yellow<\/p>\n

The color temperature is an insinuation of the atmosphere, which is \"time\" and \"psychological state.\"\u3002<\/p>\n

\"ec4ebde7j00tl6qrh00hwd000i500g7p\"<\/p>\n

Edward Hope<\/p>\n

The light source has temperature..<\/p>\n

CANDLES ARE ABOUT 2,000 K, MIDDAY SUN IS ABOUT 5,500 K, SHADOW IS ABOUT 7,000 K<\/p>\n

IN REALITY, THE LIGHT CHANGES OVER TIME. AND IF AI IS NOT TOLD OF THE COLOR TEMPERATURE, IT WILL USE NEUTRAL COLOR LIGHT BY DEFAULT TO MAKE THE IMAGE LOOK FLAT<\/p>\n

2. How to write words with colour temperature<\/p>\n

Error:<\/p>\n

\u266a warmlighting \u266a<\/p>\n

AI'S GONNA HAVE AN ORANGE ALL OVER IT. IT LOOKS LIKE A FILTER<\/p>\n

Correct:
\nwarm sunlight hitting the caratter's face, cool blue imbitter light in the background<\/p>\n

This phrase creates a warm contrast, and the picture naturally divides the hierarchy and the atmosphere\u3002<\/p>\n

\"ebdae1c4j00tl6qsh00n4d000rw00g3p\"<\/p>\n

(Examples written correctly)<\/p>\n

Colour temperature and time periods<\/p>\n

Time, temperature trends, emotional performance, hints
\nmorning morning light, cool light
\nnoon neutral clear, real daylight
\nevening warm, gentle and romantic
\n# warm lamp light, cool urban shadow #
\nWarm light allows the scene to be \u201ctemperature\u201d and suitable for narratives, characters, memories\u3002
\nCold light creates a sense of distance, suitable for a sense of technology, suspicion, future\u3002
\nWarm contrast is one of the most classic building blocks of photography\u3002<\/p>\n

Integration: to give light \u201cspace, emotion, logic\u201d<\/p>\n

When you write in your direction, light, color, you're actually simulating photographer thinking<\/p>\n

Example:
\na woman standing near a window,
\nno, i'm not,
\nsoft highlight on her face, background in cool shadow,
\n\u266a medium making light \u266a<\/p>\n

In film photography, light is often called \u201cthe first language of visual narrative\u201d. Roger Deakins has a classic saying:<\/p>\n

\"Light is not just what you see; it's how you feel what you see.\"<\/p>\n

IT'S THE SAME THING WITH THE A.I. GENERATING. YOU WRITE NOT JUST \"THE DIRECTION OF LIGHT,\" BUT \"THE DIRECTION OF EMOTION.\"<\/p>\n

Cold light creates loneliness<\/p>\n

Sidelight increases the drama<\/p>\n

Reverse light can create a sense of hope or end\u3002<\/p>\n

WHEN YOU CAN DESCRIBE THE LOGIC OF LIGHT, NOT THE ADJECTIVE OF LIGHT, AI CAN REALLY UNDERSTAND THE PICTURE YOU WANT<\/p>\n

Practice direction control:
\nLeft light \/ right light \/ back light to compare AI results\u3002<\/p>\n

Practice light control:
\nchange the area of the hint \"bright on \/ dark on \" to see if the subject is stereo\u3002<\/p>\n

Practice color temperature control:
\ngenerates the same person and feels the emotional difference by comparing the warm sunlight with the cool equal light\u3002<\/p>\n

Watching real photography:
\nAnalyzing how photographers use light to tell stories - like Gregory Crewdson's narrative light, Deakins' natural light control, or Steve McCurry's warm comparison\u3002<\/p>\n

Creates its own light template library:
\nEach successful hint is recorded, indicating three parameters: direction, light ratio, and color temperature, and gradually developing a personal style\u3002<\/p>\n

AI DOESN'T UNDERSTAND PHOTOGRAPHY, BUT IT CAN READ LOGIC. IT IS NOT A PILE OF ADJECTIVES, BUT A REPLICA OF THE PHYSICAL STRUCTURE\u3002<\/p>\n

Remember the triangle formula:
\nLight = Direction x Light vs. Colour<\/p>\n

WHEN YOU CAN EXPRESS THESE THREE LAYERS OF RELATIONSHIPS IN A HINT, AI NO LONGER PAINTS, BUT PAINTS LIGHT\u3002<\/p>","protected":false},"excerpt":{"rendered":"
