Question: how to turn off the flash/ different effects?

I am not happy with my sony cybershot dsc-t500's flash, so how to I turn it off?
and also, in my precious sony cybershot camera it gave an option of taking pictures in black and white or sepia, that camera was way cheaper, yet I liked it better, does dsc-t500 have any of those features? and how can I turn the flash off?
