ISO 50

ISO 5000

What ISO really does is that it refers to the film speed and it also captures the background light. It captures the background light and lets more light in so that you can see your background good and the flash actually makes your picture a lot more blurry. Whe I used the flash it made my background very blurry and you couldn't make out the lights and with the ISO you can see your background. Over the course of the pictures I can see that it makes this weird texture to all of my pictures and makes them more visible. I would actually rather use the ISO so that it makes my pictures a lot more brighter and lets more light in. You have to be very careful that your not letting in to much light or else it will make your pictures very bright and not able to see anything or make them blurry sometimes
