FLASH

ISO refers to the film speed, and how sensative the film/pixels are to light. The difference in my photos is that with flash the person came out bright and clear. With ISO 50 it became a little brighter but you could still not see my partner good. With ISO 400 it becomes brighter and you could see my partner but its a little grany, and in ISO 5000 there is way more light just that it is super grany and blurry. Over the course of the pictures it shows more light but as it shows more light and you bring the ISO up it becomes more blurry. When you would like to see lights of some kind behind your subject like christman light, if you would of used flash you would see your subject but not the lights. You have to be careful not to let to much light in when using ISO.
