ShootShifter redates and renames folders of images based on EXIF dates.
Two photographers made photos from the same event:
- P1: old camera with small memory cards -> three folders, each with imagenames "DSC00001 - DSC00xxx".
- P2: modern camera -> one folder with imagenames "P6150001 - P6170xxx".
Both camera-dates were not synchronized, so the images are in the wrong order when imported into iPhoto, for example.

So, let's fix this mess... launch shootShifter and drag the folders onto the app.

Thumbnails for all images are created and displayed in chronological order.
You can click on individual images to view a more detailed preview.
Select one of the folders to make it the active one (the thumbnails are moved a few pixels up)

Now you can move this active folder in time: Either by modifying the changes-interface in the upper right corner, or by simply dragging around one of its thumbnails.

Alternatively you can also double-click one thumbnail and directly change the images date and time.
