A simple little shot this one, our dog Dyogee(pronounced D.O.G.) looking anywhere but at the camera, talk about a reluctant model. She is posing down at Great Falls, Virginia side.
On this photo I made a classic mistake, the ISO setting wa
s way higher than needed for this amount of light, the truth is I was taking a few shots in the shade and forgot to change my settings when I came into the sunshine. No major problems as it turns out, but still I would have preferred this shot taken at ISO 100. For those that do not know,ISO is the sensors, sensitivity to light, the higher the number the more sensitive, the problem with high ISO numbers is they decrease the quality of the picture, the better the camera, the less obvious the 'noise', but still you can loose edge sharpness due to noise correction.
The time to use high ISO's is when the light is low, you are indoors or you cannot use a flash, museums and the like.
Speaking of flash, I did use a fill flash on this shot, with that much brightness in the back ground, I would of lost Dyogee to the shadows if I did not light her up to bring the light hitting her from the front to a similar level as that behind, it also allowed the texture of her coat to come through.
