Need some guidance

[Tank]

Hi all,
I’m completely new to photography and need a bit of help. I’m shooting on an EOS 600D. Love the camera, but there’s one thing I can’t figure out and it’s driving me crazy.
What settings do I need to have it set at to take long exposure photos without the photo just being a white screen. I’ve played with aperture and lens timing, but I just can’t seem to get it right.
I know it’s probably a very silly question, and I’m kinda expecting some smarta$$ remarks, which I guess I deserve to a point, but any useful replies or some guidance would be greatly appreciated and I would be very thankful.
Thanks in advance folks. 🙂

Love the second shot!

I was going to add flowing waterfalls is simple using Photoshop.  No special camera tricks required.

A long shutter time is a "camera trick'?

Yes it is.

At what shutter speed do we transition into tricks vs photographic choices
?
