Denise,

To be able to get a very well composed, properly cropped, and correctly exposed slide everytime regardless of the lighting conditions is an art. What is produced it a finished product. For years I did just that. It is excellent training for making black & white and color prints by hand. This ability minimizes both the use of film and the amount of dodging, burning, bleaching, and cropping in the darkroom. It requires getting everything right the first time.
