Text black is not the darkest black, it is the cheapest black that doesn't suffer from plate alignment issues (ie. K only). Photographic black is the darkest possible black that is within the total ink load the printing process/ink cost limits/drying time limits applicable. This will be a composite black (CMYK), and generally doesn't suffer as much from plate alignment issues, since images are less likely to have distinct edges, while visible contrast is critical to the perceived image quality.
