Beauty dishes and octaboxes are two of the most common lighting modifiers out there, with almost every portrait studio in existence owning at least one of the two, if not both. They are not identical, though, and each renders your subject in a unique way, which is why it is important to understand the differences so you can pick the proper one for your style and clients' needs. This great video tutorial will show you a deep look at the two options, how they differ, and which is appropriate for different situations.
Coming to you from John Gress, this helpful video tutorial will show you the differences between octaboxes and beauty dishes for portrait work. Both modifiers are excellent options for portraiture, though they do have their differences. Octaboxes generally give a bit softer light that is flattering on pretty much any subject and thus, useful as a first choice. On the other hand, if you are looking for a bit more punch and contrast, a beauty dish can offer that, which will allow you to bring out more texture and detail as well as your subject's facial structure. Check out the video above for the full rundown from Gress.

It also depends on the skin tones. Darker skin tones works better with softer light out of a soft box
