想問下加咗CPL可唔可以再用hood? 我見CPL前面塊LEN係可以轉，如果落咗hood就轉唔到，想請問各位ching CPL既正確用法。

It's not about "HOW" but about "WHAT" and "WHY".

Suggest you to search through the web to learn more about what is polarizing filters and circular polarizing filters and what can they do, before you ask people HOW to use it, just for the sake of it.

Once you managed to understand, you won't be asking the questions.

Plus, hood and CPL are totally independent.

Usually, the hood is unnecessary if you use the CPL.
