单镜头反光照相机，（Single Lens Reflex Camera，缩写为SLR camera）又称作单反相机。它是用一只镜头并通过此镜头反光取景的相机。所谓“单镜头”是指摄影曝光光路和取景光路共用一个镜头，不像旁轴相机或者双反相机那样取景光路有独立镜头。“反光”是指相机内一块平面反光镜将两个光路分开：取景时反光镜落下，将镜头的光线反射到五棱镜，再到取景窗；拍摄时反光镜快速抬起，光线可以照射到感光元件CMOS上。

video2brain是与Lynda、FXPHD等类似的教育网站，不过video2brain四种语言版本让其更加国际化，手机系统编程是最受欢迎的课程，但是正如所有的教学网站一样，CG教学仍占有大部分篇幅，这和CG行业更新速度快、更易于自学的特性一致，video2brain囊括了大量学院派的教授，让课程深度上能够长期保持顶尖水平。
