High ISO Photography

Recently I have been having a discussion about high ISO photography. We all know that as ISO increases, so does the noise that shows up in the final image. We know that we should try to shoot using the lowest ISO possible under the prevailing conditions. But often a low ISO setting just won’t work, so where do we draw the line as far as how high to go? My general rule of thumb is that I push it to the lowest ISO that will still give me the proper exposure in combination with a small enough aperture and a fast enough shutter speed. Happily, today’s dSLR’s are capable of some amazing results at ISO levels almost unheard of not too long ago.

This week I attended my grandsons’ pre-school moving up ceremony, and had to make some decisions. I didn’t want to use my off camera flash for a number of reasons – one of which was that if I were to shoot in a rapid fire mode, the flash would not be able to keep up with me. So I cranked the ISO up to allow an aperture of f/8 and a shutter speed fast enough to accomodate a long focal length as well as the high energy level of 3 1/2 year olds. There was also an issue with mixed lighting, as the location had large windows which let the sunlight in as well as being lit by mercury vapor lamps – two very different colored light sources.

The follow photos are some of the results. These were processed from the RAW files using Adobe Camera Raw in Photoshop CS6. Aside from the usual tweaking, color balance was adjusted and noise was minimized as much as possible.

What do you think of the results?
