I do Sunset Love Xinyuan Photography for free with a relative. Should I do it as a career or as a business?

If you take free sunset love photography with a relative, you'd better do it as a career. Because you are relatives, if you do business, you will inevitably have a profit mentality. If your career does not do well, the business will not do well either. If you treat it as a career and don't worry too much about gains and losses, your career will be successful and your family relationships will not be damaged. Besides, you are taking photos for free, so there is no need to treat it as a business.
