Is there any more equipment that could enhance my films? Like lighting and other equipment?
Good that Alcove got in first because the most important
equipment that could enhance your films are a good selection
of mics, an audio recorder and other associated audio gear.
Or at the very least an excellent shotgun mic and a boom.
And FrankLad offers excellent advice.
Lighting will also enhance your films. Not just the equipment,
but learning how to use light. A professional camera without
professional sound and lighting is not much better than a
consumer camcorder.
You don't need to buy professional lighting and grip equipment.
Most filmmakers rent these items, but it's great to have on hand
some lights with stands. Even if you are only using a few clamp on
lights from a hardware store and a paper lantern or two your films
will be enhanced.
As you progress to other equipment, items like c-stands, flags,
scrims and cookies are great to use. Then there is equipment used
to give more fluid motion to the shots like a dolly and a jib.
