If iCloud Photo Library is off, will an iCloud backup of m iPhone also back up my photos on the device?

I do not use iCloud Photo library because I take a lot of picture with my DSLR that I keep in photos on my macbook which I do not want synching to my phone. So my question is this, if iCloud photo library is off, will my iPhones back-up to iCloud include the photos that I take on my phone? I need to wipe the device due to another issue I have so I want to be sure the photos I have taken on my iPhone, which currently live on my iPhone, are backed up in iCloud.
