I've seen lots of people talk about and work with ring-flashes, or using ring-flash adapters for their speedlites. Some use them in single flash setups, both on-camera and off-camera, other use them in multi-light setups.
I understand the advantage of a ring flash in macro photography, but I've seen some portrait photographs with a ring-flash actually made (IMHO) subjects look worse than if I used bounced flash for example.
- What would be the advantages that I could gain if I used a ring-flash in portrait or wedding photography?
- Are there and what are possible disadvantages?
