Here are some challenge exercises, without much in the way of

What do you think of the first picture below, taken in a market in Vietnam? I

attention on the woman, can you blur out the background, as in the second photo?
(Carefully select the background, then apply a 'Gaussian blur'.)

Try to change the first picture below, taken in Mineral King,
California, into the second...
