<p>I'm working on getting images from her. <br>
She is using the external flash as the Main light and ambient as fill. The pop-up should only be communicating with the external flash. The ST-E2 doesn't have a flash bulb to add any exposure to the image. I've suggested that as an alternative, but she should need it to do what she's trying to do.<br>
This may just be a case of getting it repaired. I just wanted to avoid that option if it's not broken, but just user error. From reading the manual and checking her settings, she's got everything set the way it should be (that I'm aware of) but there are lots of hidden settings that can affect these things, so I figured I'd reach out.</p>
