>>3460492the concepts themselves are fairly straightforward and i think you would learn more just through experimentation with a digital slr or mirrorless, assuming you have one.
having said that, i have a used book i bought from 1977 called the photographers handbook which is full of great info and interesting photos. it was written in a time when all cameras were manual (for the most part) so there is an emphasis on technique. you can probably find a copy on ebay for a couple bucks and is definitely worth a read
