I am not an expert, but just starting to learn and I want to add a speedlight to my kit, but I don't know where to start. Im tyring to take some indoor 'in-use' product shots. I have a Canon 6D and was suggested the Canon 430eX III RT. That speedlight seems good from what I've read, but I'm not for sure. Additionally, I have no idea what I would need to to be able to use it off camera. I'm looking for any suggestions. Questions: Really know very little able triggers and such... Do I need a transmitter or anything to connect with the flash? And which style is recommended? I'm starting with 1 off camera flash, but if I want to go for a 2 flash system how do they interact/ does a 2 flash off-camera system make sense? Does a off-camera flash need any extra battery? Thinking about a soft box because I'm used to them, but should i just start with an umbrella or similar first? Looking for recommendations on light stands, soft boxes, umbrellas, transmitter, flash mount, or anything else I need. Any thoughts are greatly appreciated!
