Hello everyone! I currently own an used Canon t3i, and it is an amazing camera that suits me very well. But recently I decided to get started on flash photography, and realized that my camera's flash pops up, fires, but the image is still very dark. It isn't a shutter/aperture/ISO problem, since I've tried all combinations with the flash firing. I haven't found solutions for this issue anywhere, and I was hoping someone could help!

Thanks in advance!
