I'm new to using external flashes and having a lot of trouble. I have a Canon Rebel EOS T5, an Altura Photo E-TTL Auto-Focus Dedicated Flash (AP-C1001) with Altura Photo Wireless Flash Trigger with Remote Shutter.
I can get everything to work together, the wireless triggers connect to my camera and set off the external flash (no I do not use the built in camera flash), but when I go to take the picture at the max sync speed 1/200s, the picture remains dark and underexposed. The distance isn't an issue, the flash power is 1/1 and very bright, and even when I bring the flash less than 5 feet away from the grey card or any subject, everything is still dark.
Also when I have the flash mounted to the camera via the hotshoe, and take a picture, it does become lighted from the same distance and camera settings.
Any ideas or suggestions to fix it?
