I have a Rebel Xti with a Speedlite 550EX, but I am not quite getting the lighting I am looking for when taking photos of my 6 month old son. I was thinking about buying a entry level lighting kit. Something that will allow me to take near studio quality images with out being handcuffed from studios about what package and what photos I am allowed to have. Can anyone recommend a lighting solution that will allow me to take better portraits at home without spending a fortune on equipment? I am very happy with the Speedlite 550EX a lot of the time, but I find there are many times it is not perfect.
