An iPad isn't exactly the best tool for capturing photos. They're equipped with cameras similar to what you'd find in an iPhone, so they do a decent job of it in a pinch. They are also great for video conferencing due to their large screens. It's also worth noting that photographers often find iPads to be excellent tools for processing images captured on a DSLR or mirrorless camera while they're on the road. I'd personally recommend Adobe Lightroom Mobile as the ideal app for on-the-go iPad image processing.
