Shutter Speed vs Screen Darkness

[CassiLynne20]

I'm still very new to cameras, and I have a Rebel T5. When I get my shutter speed up, my photos are so much darker they're practically black. I know this has something to do with the light getting in, but I don't know how to fix it right in the settings. I've played around with it best I can figure, but don't know how to fix it. Even with a SUPER bright flash, it still looks black at the higher shutter speeds.

Please help.

Thanks!

Also look at each change notice what it did. You’ll soon catch on. However if you just want nice snapshots stick with P mode.
