Most, if not all studio strobes have a modeling light function, which can also be used as an easy continuous light source without any additional equipment. So why use a continuous light source?
Immediate effect.
When using a continuous light source, the lighting pattern, ratios etc can be seen on the subject immediately and if need be adjusted before even picking up the camera. This is extremely beneficial and a time saver as a starting point in how and where to place that flash most effectively.
One other advantage is the low power output. There are often situations where event the lowest power setting on the most low powered flash is still too much… yes you can stick on ND gels, but that’s another topic. What this low power output does is let you mix and balance your lighting with ambient much more smoothly rater than just nuking everything.
For wedding shooters this could mean a romantic couples portrait under candle light, for model shooters, well the possibilities are endless.
In here, I wanted the environment dimly lit so I can use high ISOs to create digital noise.
