A place to politely discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.
A grid will control light spill, but it won't change the quality of light. A close, gridded, softbox will put soft light on your subject. A speedlight will put hard light on your subject
If you're doing most of your lighting with softboxes, a speedlight grid won't be very useful
I just read your post again. Words are important. Thank you for answering my question
