Any kind of camera will do that has a shutter that can be made to remain open for a time exposure.
这个do是不及物动词,“行、可以、足够、合用”的意思。
那么就会想到这是that引导的定语从句与谓语之间产生了分隔。还原后你瞬间就明白了:Any kind of camera that has a shutter that can be made to remain open for a time exposure will do. 但是,还原后头重脚轻,句式不够优美,所以成分分隔写法是最佳处理办法。
