Technology advances have changed the face of photography as we knew it
20 to 25 years ago. Our cameras now have the ability to capture images at high
ISO’s with unbelievable results. “Golf Ball” grain is no longer a creative option.
The camera’s ability to capture at these high ISO’s means that our little
portable flashes now are a realistic lighting option in the studio or
on-location. They are an inexpensive form of lighting that can be modified,
turned up or down like a power pack and guess what – you don’t have to bring
your 600lb capacity cart to lug them to shoots.
In class we discussed the dreaded Guide Number and how it mathematically
relates to distance and aperture. Using their mathematical skills they can now
place their portable flashes at any distance and know what the flash output
will be. Conversely, they can chose their depth of field and now calculate how
far away their flash has to be from their subject – enough math already! Let’s just
look at some of the favoured results of their “Portable Flash” assignment using
two flashes. Even "Spiderman" agrees Portable Flash "rocks"
