Yes, the SB-600 will provide more power and range than the built in Speedlight. Using bounce flash will soften the light giving a more natural appearance to the image. When using direct flash for additional range the higher profile of the SB-600 will also reduce the probability of red eye because the center of the speedlight is further away from the centerline of the lens. Good Luck and Enjoy your Nikons!
