I have started learning about editing photos , I want to edit photos for printing only. Therefore I need to know about resizing , Howerver, I have spent weeks , reading and watching videos about this , and they all speak the same editing language without being specifically about what is needed,and what for I mean theto follow etc. For example, resolution and pixel ,dots per inch,they all say about it in sumary short cuts etc. In order to resize a photo there is needs to be more specific iformation that is needed about it when to do custom resize photos. so if someone could assist me wiht this.I can start rezising my old photos. Thanks.
