The Cure for Motion Blur: Auto ISO

Whenever we shoot while hand-holding the camera, it’s impossible to keep the camera from moving around.  No matter how steady the photographer’s hands are…no human can hold a camera perfectly still.

This usually isn’t a problem while shooting outdoors during the day. Enough ambient light is available from the sun, even under thick clouds, to keep the shutter speed well above the “motion blur due to camera movement” threshold.

But, when we shoot at dusk or dawn, at night, or indoors without a powerful flash, the shutter speed slows down significantly (assuming a constant aperture and ISO).  And in these situations, we inevitably have to ask the following question:

How slow can shutter speed go without creating a blurry image? Continue reading “The Cure for Motion Blur: Auto ISO”

The Exposure Triangle, Part II: What Is “Exposure” and What Is A “Stop”?

Each of the three parts of this photograph, from left to right, denotes a one stop increase (a doubling of the amount of light) in the exposure.

In Part I of “The Exposure Triangle” we established the essential definitions of Aperture (f-number), Shutter Speed, and ISO.

But, two vitally important questions must be answered if we want to gain complete control over our camera’s settings:  1) What is the exposure of  a photograph, and 2) How do we measure what happens to exposure when you raise or lower Aperture, Shutter Speed, and ISO?

My Latest Visit to Kilgore Falls

Single exposure. Nikon D810, Nikkor 24mm f/1.4 at f/8, ISO 64, 50s. Singh-Ray 5 Stop ND filter was used to slow down exposure.  Also, to give the image that subtly soft appearance, I used the Singh-Ray Tony Sweet Soft-Ray Diffusion filter. (Click on the image for full size)

Autumn Road

Nikon D810, Nikkor 35mm f/1.4 at f/8, ISO 64, 1/15s. (Click on the image for full size)

If you’ve been to my website previously, this shot may look somewhat familiar.  The road depicted here is in Hunt Valley, Maryland, adjacent to the north side of Shawan Road, just east of The Oregon Grille restaurant.  Every fall, I head over to the road and photograph the foliage.  The above photograph was taken this morning.

Under a Full Moon

From Cook’s Meadow in Yosemite National Park.

Nikon D810, Zeiss Distagon T* 25mm at f/4, ISO 800, 20s.

For those of you who may be interested in visiting Yosemite to capture one of the many waterfalls cascading over the granite cliffs, the ideal time of year is mid to late April.  During that time frame, the snow melt off the mountain tops is at full force, instigating the high rate of flow over the waterfall.
