Softbox to compliment 120cm octa with grid
I've made a small home studio for some practice, starting with 2 deep umbrellas (51", silver and white) and ordered a diffusion sock for them, then bought an octa (120cm (4")with grid) and I'm thinking what's next - rectangular softbox with grid, there are 60х90, 70х100, 80х120 cm, or maybe one more octa (140cm (almost 5") with grid)? Or even a beauty dish with grid? What is better for two light setup? In the studio I used a big octa and white umbrella for that, but in a small place the grid will help with spill... What do you think?
