NOTHING IS REAL

NON-LINEAR LIGHTNESS 非線性亮

Enter your text here...THE HUMAN EYE IS MORE SENSITIVE TO THE CHANGE OF LIGHTNESS IN THE DARK, THE LIGHTNESS IS 50% FOR A RELATIVE LUMINESCENCE OF AROUND 18% RELATIVE TO THE REFERENCE WHITE.

人眼對暗部變化更敏感，實際亮度約為 18% 時，人眼感知亮度為 50%。

NON-LINEAR LOUDNESS 非線性響

Enter your text here...THE HUMAN EAR IS SLOW TO LOW TUNE, IT NEEDS MORE DECIBEL TO ACHIEVE THE CORRESPONDING LOUDNESS IN HEARING, WHILE HIGH TUNE IS OPPOSITIONAL.

人耳對低頻不敏感，需要更大聲壓才能在聽覺上達到相應效果，高頻則相反。

UNREAL TONE 超真實色調

THE HUMAN EYE PERCEIVES LIGHT WITH THREE KINDS OF CONE CELLS AND ONE KIND OF ROD CELLS, AND THE DIFFERENCE OF CELL NUMBER AND ITS SENSITIVE FREQUENCY BAND LEADS TO DIFFERENT BRIGHTNESS PERCEPTION OF DIFFERENT COLOURS, NIGHT VISION MAINLY DEPENDS ON ROD CELLS (DOTTED LINE IN THE LEGEND). TO USE TONE COLOUR SPACE FOR COMPENSATION.

人眼以三種視錐細胞與一種視桿細胞感受光線，細胞數量與敏感頻段的差異導致人類對不同顏色有不同亮度感知，夜视主要依赖视杆细胞（图例虚线）。建議使用含色調調節的色彩空間進行補償。

EX: HUMAN EYES VS OBJECTIVE EYES 案例：人眼與客觀世界差別

IN ‘IMPRESSION, SUNRISE’ OF MONET, THE SUN IS IN THE SAME SATURATION AND BRIGHTNESS WITH THE SURROUNDING ATMOSPHERE, WHICH CAN'T BE SEEN AFTER COLOUR REMOVAL AND FILTERING ON HSV MODE ON COMPUTER. BUT THE SUN IS VERY BRIGHT IN HUMAN PERCEPTION AND CAN BE CLEARLY DISTINGUISHED FROM THE SURROUNDING ATMOSPHERE.

莫奈的日出里，太陽與周圍大氣處於同飽和度同亮度狀態，去色過濾後無法顯現，而人眼感知中太陽非常鮮艷，能與周圍大氣明顯區分。

UNREAL TUNE 超真實音調

THE HUMAN EAR WILL ACTIVELY ANALYSE THE FREQUENCY DOMAIN OF COMPOSITE SOUND WAVES, DISASSEMBLE FUNDAMENTAL, HARMONIC AND OTHER CONSTITUENT SOUNDS, EVEN ACTIVELY COMPENSATE THE MISSING FREQUENCY BANDS. THE FARTHER AWAY FROM THE FUNDAMENTAL FREQUENCY, THE MORE DISCORDANT THE OVERTONES ARE.

人耳會主動分析復合聲波頻域，拆解出泛音列與組成音，甚至主動補償缺失頻段。離基頻越遠的泛音越不和諧。

EX: 3RD NOTE AND FLAT 9TH NOTE 案例：三度音与降九度音

IN THE MOST HARMONIOUS TRIAD CHORD, THE MELODY USES THE THIRD TONE TO PROTRUDE ITSELF, REFER TO THE "PACHELBEL’S CANON".IN THE MOST EXCITING DOMINANT CHORDS, THE MELODY USES THE NINTH DEGREE NOTE TO PROTRUDE ITSELF, REFER TO "AUTUMN LEAVES".

在最講求和諧的大三和弦中，旋律使用三度音能凸顯自身，參考「卡農」。在最講求刺激的屬和弦中，旋律使用降九度音能凸顯自身，參考「秋葉」。

SYNESTHESIAS 聯覺

BOTH ELECTROMAGNETIC WAVES AND MECHANICAL WAVES CAN BE PERCEIVED BY HUMAN BEINGS, AND THEIR VARIANT CAN LEAD TO RICH FEELINGS, AND PEOPLE WILL PRODUCE SYNESTHESIAS ACCORDING TO THEIR COMMONALITIES.

電磁波與機械波都能被人類感知，其頻率變化可帶來豐富的主觀感受，人腦會根據其共性產生聯覺。

COUNTER-INTUITIVE 反直覺

HUMANS GENERALLY REGARD RED AS A SYMBOL OF HIGH TEMPERATURE AND BLUE AS LOW TEMPERATURE, BUT THE OPPOSITE IS TRUE. DURING THE DAY, WHEN THE SKY IS CLEAR AND TRANSPARENT, THE FAR PLACE IS BLUE AND LOOKS COLD, IN FACT IT HAS THE SAME TEMPERATURE OF THE NEAR PLACE. THE BLUE COLOUR IS THE RESULT OF RAYLEIGH SCATTERING. IN THE EVENING, THE SHORT WAVE OF PHOSPHORESCENCE IS FILTERED, AND THE SUNLIGHT SEEMS RED AND HOT, BUT THE ACTUAL TEMPERATURE IS LOW. 
PEOPLE ALSO BELIEVE THAT THE LOW TUNE IS WARM, BUT IT CONTAINS MORE DECIBEL AND RICHER OVERTONES AT THE SAME LOUDNESS. THE HEIGHT TUNE CONTAINS LESS DECIBEL, AND THE OVERTONE IS RELATIVELY SIMPLER, SO IT FEELS COLD. IN FACT, MORE ENERGY IS NEEDED TO MAINTAIN THE HIGH LEVEL.

人類普遍認為紅色象徵高溫藍色象徵低溫，事實相反。白天空氣透視，遠處偏藍色調，看似溫度偏冷，實則與近處等溫，藍色調是瑞利散射的結果。傍晚陽光短波被過濾，偏紅色調，看似溫度偏熱，實則輻射強度低。人類還認為低頻聲音溫暖，實際是同等響度下低頻聲壓更大，並伴隨更豐富的泛音。同等響度高頻聲壓更小，泛音相對單調，聽感冷冽，實際同況下需要更多能量維持高頻。

MAGICAL MYSTERY TOUR

RENDER 渲染

DIFFERENT OBJECTS HAVE DIFFERENT OPTICAL DIFFERENCES, RESULTING IN DIFFERENT VISUAL EFFECTS.THERE ARE SPECULAR REFLECTION, DIFFUSE REFLECTION, SUBSURFACE SCATTERING DIFFUSE, AND THE PHENANTHRENE EFFECT OF WATER, ETC. IT CAN ALSO BE CUSTOMIZED TO PRODUCE A NEW LIGHT AND SHADE EFFECTS WITH THE TEXTURE AND THE ENVIRONMENT, AND THESE TECHNIQUES CAN BE CALLED RENDERING.

不同物件有不同光學差異，形成不同視效。有鏡面反射主導的金屬效果（金），有漫反射主導的石面效果（土），有次表面散射主導的樹葉效果（木），有菲涅爾效應明顯的水面效果（水）。也可自定義復合材質，影響環境產生光影效果，這些技法都可稱之為渲染。

SYNTHESIZER 合成

THE HARMONIC SERIES OF MUSIC INSTRUMENTS ARE DIFFERENT, IT FORMING DIFFERENT TIMBRE. THERE ARE SOME PULSE SOUNDS, PERFECT PITCH AND ATTACK SOUNDS, RICH OVERTONES AND RESONATE WIND SOUNDS, AND MALLEABLE HUMAN VOICE. YOU CAN ALSO SELECT SOME STRENGTHS IN THE HARMONIC SERIES TO FORM NEW CHORDS. THESE PROCESSES CAN BE CALLED SYNTHESIS.

不同樂器泛音列組成有差異，形成不同音色。有單調規整的脈衝擊打聲（鼓），有音准完美無延遲的鋼琴（絲），有氣柱共鳴泛音豐富的管樂（竹），也有複雜可塑的人聲（肉）。也可在泛音列中選取部份強調，形成和弦。這些過程都可稱為合成。

EX: ARTIFICIAL PHYSICAL 案例：人造物理

IMPRESSIONISM ARTIEST WILL USE THE COLOUR PRINCIPLE TO RECOLOUR THE SHADOW IN ORDER TO MAKE THE LIGHT LINE BRIGHTER, AND THE MUSICIAN WILL RECOLOUR THE OVERTONE OF OTHER INSTRUMENTALS TO EMPHASISE THE VOCAL, THESE WILL NOT CHANGE THE THING ITSELF. BY CHANGING THE SURROUNDING ENVIRONMENT TO MAKE THINGS MORE ‘NATURAL’ IN HUMAN’S IMPRESSIONS.

印象派畫家為了讓光線更明亮會使用補色原理給陰影上色，混音師為了凸顯人聲會讓其他同頻段樂器泛音染色，本質上都沒改變事物本身，卻通過改變周圍環境讓事物更符合人類印象中的樣子。
