You can make a hard light soft but you can’t make a soft light hard.
Keep this in mind when ordering equipment before your next shoot. Carry some hard sources that will provide the punch and directionality you might need. Then save time and money when you transform those lamps into soft lights by bouncing them off almost any surface you can imagine.
Obviously, the principles of physics dictate that it doesn’t work the other way around…but that’s OK. Plan ahead and it won’t present a problem.
