VIP EYE CARE St. Petersburg Customer Appreciation Event May 2013

VIP Eye Care boutique in St. Petersburg Florida hosts another customer appreciation event in May 2013 - Nikon D300 Tamron 17-50mm @ f/5.6 ISO 800 1/60th SB-800 @ 1/4 power hotshoe mounted

I returned to VIP Eye Care boutique in the downtown St. Petersburg area to photograph another one of their customer appreciation events.  VIP has been my most frequent photography client, in addition to my optomology needs (contact lenses).  This time the event happened while it was still light out letting me use some of the available natural light for different looks to shots.

This is a photograph of a reflection above, with the light from my SB-600 sidelighting her as seen in the reflection.  I always like to try out new tricks when possible in order to create new event photographs for clients.

Such a purposefully overexposed shot was never possible at the other events I photographed for VIP after the sun went down.  I thought it was interesting she kept her old glasses on her head while she tried on a new pair.

I asked this sunglasses rep to hold out a pair of them as far extended as he could as I wanted to make a shot with just the sunglasses in focus and him and the background the bokeh.

Photography Tip - think of ISO like a pair of sunglasses

Over the past few months I have started to describe ISO to my photography students like a pair of sunglasses.  You have sunlight hitting your eyes.  When wearing sunglasses your eyes feel all nice and comfortable even with all that sunlight.  However, if you take off your sunglasses, the same amount of light is hitting your eyes, except now it hurts and you squint.  There is a cost to taking off your sunglasses.  

It is the same thing with ISO.  There is a certain amout of light hitting your DSLR camera's sensor.  If you increase the ISO setting, the same amount of light will hit the sensor, except now the camera's sensor with a higher ISO is more sensitive to that same amount of light.  This is just like your eyes getting more sensitive without sunglasses.  The tradeoff with no sunglasses is squinting.  The tradeoff with high ISO is introducing noise, grain and artifacting into the photograph.  

This is why I usually only increase ISO last when trying to get the correct exposure.  Most of the time I will use the largest aperture possible with the slowest shutter speed possible.  Once I hit those limits, only then do I start to increase ISO because I want to maximize image quality as much as possible.
