Nice to Recover Photo for Mac is a tool that specializes in recovering images, video and audio.
If you have accidentally deleted a file via the Trash, the main option is to use Quick Recovery. This performs a through scan of your hard drive and should locate the missing files or at least remnants of them. However, if Quick Recovery fails to find anything, Deep Recovery scans the disc more slowly (at about 3GB per minute) and probes more deeply for missing data.
If you've lost data on a partition, Lost Partition Recovery hunts for badly formatted or deleted data on a partition. Finally, Photo Recovery recovers photos, music and also video that's missing or corrupted on your Mac. This feature also works on cameras and iPods that store photo data.
