I'm looking for a book about digital photography that is dealing with the technical stuff in an exhaustive way. It maybe something like explaining from what is a histogram to describing how sensors work, optic formulas etc... I had such a book for Video so I hope it exists for photography but I can't find anything. Thanks!
I don't think you're going to find a book that ranges from the basics, like what the histogram tells you, to advanced stuff like optical formulae. However, if you have a list of topics in mind you can create your own book with Wikipedia's book creator, which lets you compile a list of Wikipedia topics together into a single PDF or ODF file, or even order a printed copy.
