Fluorescent lighting?

Slow shutter speeds are a liability when shooting portraits such as the example posted by the OP.

Sorry but I may not be making myself clear. The statement about "needing" fast shutter speeds with continuous light implies that slow shutter speeds with continuous light will give unsatisfactory results. This may or may not be the case depending on the situation. I have taken many portraits at shutter speeds of 1/15 to 1/40 sec. using continuous light both tungsten and fluorescent as well as many shots of still life where the shutter speeds are often much longer. The only limitation I can think of is the possibility of subject movement such as photographing restless children. There is nothing wrong with slow shutter speeds within these limitations. Thanks

Slow shutter speeds bring in the possibility of subject motion and also camera shake. If you're hacking around at home and yield isn't an issue, continuous lighting is just fine. But if you need to consistently deliver high quality portraits, you should invest in speedlights or studio strobes.

Consider the possibility that your standards for excellence may not be universal.

Its my fault its over,,I have a bad habit of that.
Ill see what I can do with it in PhotoShop.

I know the higher the ISO the more noise you get, but the XTI does fine at 100ISO. Here is a shot with 90 second exposure.
