is it possible to recover photos which have been deleted from a memory card from a Sony Cybershot digital camera model dsc-w150

Yes, you'd need to get software from somewhere to do that. Start at the OEM sites. See sony, see all the flash makers sites and maybe even usb flash places for software to recover files. See also softpedia or maybe tucows for software. Other places are rip offs. Playing to the angels Les Paul (1915-2009)

Of course, it's possible. Recently I moved a lot of photos from SD card to my HD. I formatted the SD card and put it back in the camera. Then by accident I deleted the complete desktop of my PC, including all my photos. I know it's a folly. I tried to search with Google and found Advanced File Recovery. With the help of this program I recovered all my photos.
