Hi all! I,m a newbie in studio photography...I'm planning to buy studio strobes to set up a home studio and I would like to know if what's the difference and the effect of those strobes with lower wattage (eg. 160w) from those with higher wattage (300-600w). What are the advantages & disadvantages between the two sets. Since I'm just beginning, would the lower wattage enough to produce decent studio photos? I also need some recommendations regarding a cheaper strobe brand with acceptable performance and where can i get them. Thanks heaps!
