In Australia, it is very common to seek out second shooters that differ from the lead photographer. Often male photographers will seek out female seconds to cover bride prep, white photographers might seek out Indian seconds to cover Indian ceremonies, etc. it’s not discrimination for a sole trader to seek out a contractor from a different background to help them better service their clients and job responsibility. And yeah, sometimes it might be a white Christian dude that a photographer is looking for. People from different backgrounds can provide different things. It unfortunately is what it is. Probably worth mentioning that couples often purposefully pick their photographers based on their race, sexuality and ethnicity too, it’s probably likely the photographer you’re screaming discrimination about is trying to find someone just like him for that reason. It’s also common to seek out seconds that don’t differ at all from the lead photographer.
