I tried to use Tv (Shutter Priority AE) Mode to shot indoor full light speed 1/320 Iso 200 but the picture very dark actually it all black, i pushed iso to 1600 the picture can hardly see !
What is my problem here ? Thx

The aperature cannot compensate for your fast shutter speed.
Did the aperature reading in the viewfinder blink continuously?
Probably have to use a slower shutter speed, or a fast lens.
Set the cam to P (program) mode and check the settings the cam chooses as a guideline.

In your case, you set it as shutter speed 1/320, blinking means that the camera is telling you that even if your aperture is to open to its max (without changing ISO), there is still not enough light to properly expose the picture.

So you have to
1) make your shutter open longer
2) increase your ISO
3)both
