We are thinking at this point for Tiff and jpeg, will get both the possibilities for the adjustments and the jpeg for the viewing. About the same difference I think, but have to look to make sure. Still experimenting with the camera some. Better to learn the operation and determine the format after that fact sort of. That and when I get the gizmo later this week then we can practice on moving stuff from the camera to the storage device. Then it may not make that much difference about the file selection as long as it is one of the top two selections anyway.
