So I decided to buy a cheap flash to experiment bouncing flash on walls or ceilings. I can't stand flash in pictures so I thought this would be a great way to try, and seeing these things are barely 60$ on eBay it wasn't much of an investment to see if I can deal with it.

Now I just put the flash on the camera, set it to "auto" and the pop-up flash tries to come out even though the flash is mounted on the camera. I thought that the "auto" mode would use the mounted flash instead of the pop-up flash, and then I could adjust the flash settings depending on what I want.

If I set it to "auto no flash" then the mounted flash doesn't fire.
