I would like to edit still shots from the GoPro. What do you guys use? Key features I am looking for are very basic Zoom/Crop/ add text to the photo, clean up the fisheye, . I am a PC user so I don't get much in the way of software for editing and would like to know what people are successful with for the GoPro. It does not look like GoPro Studio allows editing of stills. Your advise?
