Estimate depth of field, maximize it via hyperfocal technique. 估计一下原野的深度,通过高焦距的技术把它放到最大限度。
With SLRs, set hyperfocal distance, use moderate wide angle, release-priority AF, etc. 对单反相机，设好超焦距的距离，适当的用广角镜头（能收纳进尽可能多的景物，可以后期再裁剪）。
Hyperfocal distance? 超焦距?
Imaging definition which CCD camera works in limited distance was solved by using hyperfocal distance.Telecentric optical system was employed in order to solve the precision of measuring systems. 用超焦距方法解决了CCD像机对有限远距离范围内工作时的成像清晰度问题,采用了像方远心光路设计解决了系统测量精度问题。
