Confused about flash triggers, receivers and remote?

I'm fairly new starting out in photography and I'm confused about flash triggers, receivers and remotes. I have done lots of research but still don't get it!

Basically, I have a Nikon D850, and I need to get a flash trigger + receiver and separate shutter remote that I can have the option on syncing with, the trigger + receiver.

I can't seem to find an all in one flash trigger & receiver and remote product. Why do I have to buy them separately? Can 2 different brands still sync up? And what would you recommend for my Nikon D850?

Please no nasty comments, thanks

You will need to buy two different products. There isn't an all-in-one product available because one part is the flash, and the other part is for triggering the camera with or without a flash.

For the easiest shopping experience, the largest selection and best prices, go to either B&H (bhphotovideo.com) or Adorama.com. If you go to amazon.com, you'll just get confused; their website isn't designed well for anyone who doesn't know the exact make/model of photography/video gear that they're looking to buy. At least with B&H and Adorama you can call them up toll-free and speak with a trained professional.

You can buy the triggers and receivers as a set. The remote is always separate. Best way to go about it is to go to the nearest reputable camera store with your camera and flashes then ask them what you want. Make sure to test everything while in the store so the guys there can set everything up properly before you leave.

I use a set of cheap Chinese flash triggers I got off Ebay 4 or 5 years ago. I don't need TTL flash, so I don't need expensive triggers for what I do. One unit on the camera, and I got 3 triggers.

I also have a cheap Chinese radio remote shutter release. The only difference amongst shutter remotes is how they connect to the camera (every maker uses a different connector). Some add in timed release and all that, if you care for such things.

The maker is not relevant for either set. The shutter remote is one thing, the flash triggers are something else. You set it all up, stand back, and press the go button on the shutter release. If your flash system is on, it will fire when you do so. There's no need for the two systems to be connected, the camera firing the shutter sets off the flash triggers regardless of whether you do it from the on-camera shutter release or from a remote. The only thing that your specific model of camera has to do with it is what connection it has for the remote shutter release. Nikon and Canon both have 2 different connections. Get that right, and the rest works the same regardless of camera brand or model.
