<h3>摄影，原于银盐影像。自从法国光学仪器商人夏尔·雪弗莱（法语：Charles Chevalier）发明了日光蚀刻法，然续到法国画家路易·雅克·曼德·达盖尔(Louis-Jacques-Mandé Daguerre)将其完成为银盐印版法，从此殿定了摄影技术的开始，在1839年8月19日，法国政府决定将这一发明，作一个对“免费送给世界”的礼物，从此，启开了人类摄影技术的编章。为了记念这一贡献，人们将8月19日定义为‘’世界摄影日‘’。</h3><h3>银盐摄影法，就是将錪化银涂在一柔性材料上(胶片或纤维纸)(ISO)，光影经过一个小孔(光圈)对其照射感应的时间长久(速度)，银在光的强弱多少作用下，产生了纯黑到纯白(中间值为灰)的反应，这就是亜当司(Ansel Adams) 的 0 - 10级黑白系统。然后通过酸碱反应，将部分银去掉，最后经过氯化钠(盐)将留下来的碘化银固定在材料上(胶片或纤维纸)，形成影像。这就是我们的黑白摄影。</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>
