In Digital Photography ISO measures the sensitivity of the image sensor.
The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain.
Higher numbers mean your sensor becomes more sensitive to light which allows you to use your camera in darker situations. The cost of doing so is more grain (although cameras are improving all the time and today many are able to use high ISO settings and still get very useable images).
An example of a situation you might want to choose a higher ISO would be photographing an indoor sporting event where the light is low and your subject is moving fast. By choosing a higher ISO you can use a faster shutter speed to freeze the movement.

My Opinion:
Personally,i think that the pictures came out very good because it zooms in on the flower and the background is nice and blurry.

I like this picture the least because even though its a good picture,the I like this picture the best because it zooms in on the flower and it even background is a bit black and you cant really see whats actually there. shows what the flower looks like before it blooms,it also has a nice blury background yet you can easily see its a nice tree and sky.
Settings:
In each picture the ISO has been increased from AUTO-800
