<h3>攝影，原于銀鹽影像。自從法國光學(xué)儀器商人夏爾·雪弗萊（法語：Charles Chevalier）發(fā)明了日光蝕刻法，然續(xù)到法國畫家路易·雅克·曼德·達(dá)蓋爾(Louis-Jacques-Mandé Daguerre)將其完成為銀鹽印版法，從此殿定了攝影技術(shù)的開始，在1839年8月19日，法國政府決定將這一發(fā)明，作一個對“免費(fèi)送給世界”的禮物，從此，啟開了人類攝影技術(shù)的編章。為了記念這一貢獻(xiàn)，人們將8月19日定義為‘’世界攝影日‘’。</h3><h3>銀鹽攝影法，就是將錪化銀涂在一柔性材料上(膠片或纖維紙)(ISO)，光影經(jīng)過一個小孔(光圈)對其照射感應(yīng)的時間長久(速度)，銀在光的強(qiáng)弱多少作用下，產(chǎn)生了純黑到純白(中間值為灰)的反應(yīng)，這就是亜當(dāng)司(Ansel Adams) 的 0 - 10級黑白系統(tǒng)。然后通過酸堿反應(yīng)，將部分銀去掉，最后經(jīng)過氯化鈉(鹽)將留下來的碘化銀固定在材料上(膠片或纖維紙)，形成影像。這就是我們的黑白攝影。</h3> <h3>KODAK TMAX400 35mm </h3><h3>2020.06</h3><h3>My portrait in the city - 我的肖像在城中。</h3> <h3>ILFORD DELTA 400 6x6</h3><h3>2020.01</h3><h3><br></h3> <h3>ILFORD DELTA 400 6x6</h3><h3>2020.01</h3> <h3>ADOX HR 50 35mm</h3><h3>2020.02</h3> <h3>ILFORD HP5 6x6</h3><h3>2020.03</h3> <h3>ILFORD HP5 6x6</h3><h3>2020.03</h3> <h3>ILFORD PAN F50 6x6</h3><h3>2020.12</h3> <h3>ADOX HR 50 35mm</h3><h3>2020.02</h3> <h3>ILFORD PAN F 50 6x6</h3><h3>2020.12</h3> <h3>KODAK TRI-X 400 35mm</h3><h3>2020.03</h3> <h3>ADOX HR 50 35mm (added filter to creat contrast)</h3><h3>2020.03</h3> <h3>ILFORD HP5 400 35mm</h3><h3>2020.05</h3> <h3>ILFORD HP5 400 35mm</h3><h3>2020.05</h3> <h3>ILFORD HP5 400 35mm</h3><h3>2020.06</h3> <h3>ILFORD HP5 400 35mm</h3><h3>2020.05</h3> <h3>KODAK T-MAX 400 35mm</h3><h3>2020.06</h3> <h3>KODAK T-MAX 400 35mm</h3><h3>2020.06</h3> <h3>ILFORD PAN F 50 6x6</h3><h3>2020.11</h3> <h3>ILFORD PAN F 50 6x6</h3><h3>2020.11</h3> <h3>ADOX HR 50 35mm</h3><h3>2020.02</h3> <h3>ILFORD PAN F 50 6x6</h3><h3>2020.11</h3> <h3>KODAK T-MAX 400 35mm</h3><h3>2020.08</h3> <h3>KODAK T-MAX 400 35mm</h3><h3>2020.06</h3> <h3>ILFORD HP5 35mm</h3><h3>2020.06</h3> <h3>KODAK T-MAX 400 35mm</h3><h3>2020.08</h3> <h3>ILFORD PAN F 50 6x6</h3><h3>2020.12</h3> <h3>Silver gelatin print 5x7 on Ilford MGRC Deluxe Glossy paper</h3> <h3>Silver gelatin print 5x7 on Ilford MGRC Deluxe Glossy paper</h3> <h3>Silver gelatin print 5x7 on Ilford MGRC Deluxe Glossy paper</h3> <h3>Silver gelatin print 5x7 on Ilford MGRC Cooltone Pearl paper</h3> <h3>Silver gelatin print 5x7 on Ilford MGRC Deluxe Glossy paper</h3> <h3>Silver gelatin print 5x7 on Ilford MGRC Deluxe Glossy paper</h3> <h3>Silver gelatin print 8x10 on Ilford MGIV RC Deluxe paper</h3> <h3>Silver gelatin print 8x10 on Multitone RC Glossy paper</h3> <h3>工作中……</h3>
