Exercise 7

This exercise is about the effects of different ISO settings.  For this exercise I used a prime lens indoors and took a shot that had a contrast of detail including a plain back wall and detail in front of it.
These are the different photos taken at all the different ISO levels on my camera.

The most notable change as the ISO gets higher is the change of colours particularly the back wall and the floor.  The graining is noticeable at the very high end and there is a texture to the lamps.  When you zoom in there is a mottling of the wall also.
