Increase Your ISO To Get The Result You Need
August 12, 2011
When it comes to flash photography your ISO plays a big role. ISO signifies how sensitive our camera’s image sensor is to the amount of light present. The higher the ISO number, for example 800 the more sensitive the image sensor to light, enabling us to take pictures in low-light conditions. The downside, the higher the ISO, the more noise we get on our images.
The photo above was taken indoor, there weren’t enough light around making it challenging to take photos of this fast moving Pale Headed Saki. I would have not made this shot without raising my ISO to 800. I do this in situations when I feel that the ambient light won’t be enough give me the result I need. I would rather choose a grainy / noisy image than a blurry one.
Like on our photo above, if I shot it at ISO 100, the photo would have been dark and probably unusable, or the only choice that I have was to use a slower shutter speed which wouldn’t be possible because of how fast our guy here can move. I choose to increase my ISO so I can use a faster shutter speed that will ensure me I that I will get a sharp image, I also needed to stop down my aperture to f/5 to get details on that cute face of our model. When using flash, I always remember that if I raise or lower my ISO, it affects my flash exposure and my ambient. Like what I’ve mention earlier, when I feel that my ambient isn’t enough, I have no other option but to increase my ISO.
