讲座内容： 1. 像机的成像原理
1.1 镜头小孔成像 ® film 或sensor capture
1.2 Basic SLR working mechanism

2. The three factors for a photograph: Aperture, Shutter speed, and ISO
2.1 Aperture:
2.1.1 Concept of “stop(档)”; From bigger F# to smaller F# or vise versa: Time 1.4 or 0.7 for 1 stop change; and why 1.4 or 0.7

2.2 Shutter speed:
2.2.1 Minimum shutter for hand hold shooting: Reciprocal rule in 35 mm format

2.3 ISO:
2.4 The triangle relationship: Nearly all about photography is to make compromise —Decision making in action: what to keep, what to sacrifice

2.6 Example pictures showing
2.6.1 Portraits: Single; Group (emphasis on aperture)
2.6.2 Sporting shots: emphasis on shutter speed

3. Basic equipment and shooting skills
3.1 Hardware:
3.2 Software:
3.3 The reasonable way to shoot: Purpose is to hold your camera stable
3.4 Basic camera setting: consider manual mode (ISO as low as possible, shutter as high as possible, aperture need based. Þ Compromise!)

第三讲 奇妙的光线
主讲人:穆建西
– 浅谈摄影用光：
对数码摄影而言，后期制作中，光线因素的可调节性很大。所以人们往往忽视数字摄影拍摄用光的许多细节，而把注意力集中在构图和后期制作上。经过后期制作的作品，虽然有鲜亮抢眼的特殊视觉效果，但效果并不来源于摄影本身。
此讲从典型作品分析入手，采用摄影光线分析的方法，让学生理解光线的特性，从而掌握不同环境下的摄影光线的使用。
-正确控制成像：
亮度和对比度。
Histogram
LCD亮度
Lighter Meter：Evaluative, Partial (8%), Spot(3.5%), Center weighted Average.
Exposure Values (EV)
颜色的感知和错觉
光源的种类
自然光源：
人工光源：日光灯，钨丝灯，闪光灯（快门设置，补光）
光源的色温：
光源的性质
点光源，直射光，散射光，反射光。
不同性质光源的成像效果
暗光摄影，高调摄影，自然光摄影。
光源的位置：正，逆，测，顶，脚。
光源的层次和分布：
光线的对比度
光线的色彩：白平衡。
色彩的分解：光谱和基色，滤镜。
色彩的组合：补偿光线的使用。
被摄物体的颜色：
选择性吸收和反射：
记录光线的介质：
非成像光线的排除：
