Canon 佳能 430EX 430 EX“肥皂盒形”柔光盒
柔光罩
材质柔韧，和闪灯配合紧密，色温控制非常好。和进口的那个STO-FEN有得一拼。
柔光罩看似简单，但其技术含量非常高！
市面上的柔光罩很多，事实上好多在柔光效果、以及和闪灯的配合并不如意。
特别是色温控制，是决定柔光罩是否合格的重要因素。望大家选购的时候要特别注意！
制作材料：聚乙烯，多用于保鲜膜等无毒食品包装。
特性：薄膜时程透明装，在一定厚度下，分子呈现晶格装，使光线发生散射呈半透明装，耐温130度，有极好的柔伸性和抗碎裂，化学性质稳定。
柔光罩使用方法:
除了最远距离减去2.5的系数外，不需要作其他调整。
除了ttl模式外，不要在正常的机顶直射位置使用柔光罩。为了达到最好的效果应该采用45度斜

With OMNI-BOUNCE on Flash
Technical
Notes:The flash use was the Vivitar 283 mounted on the hot shoe
of the camera. The camera was on a tripod to maintain distance and
position. The film used was 100 ISO Color negative. The lens used
on a Nikon FE-2 was the 16mm f/2.8 Nikon full frame fisheye, (Which
accounts for the curvature of the image) that allows the true
effect of the straight on flash to be seen. The room is 30 feet
wide and the Flash & Camera were ten feet from the fireplace.
Both shots were made with the Vivitar set on the Red Auto Mode at
f/4. The OMNI shot had the flash head tilted to
45°
