Answer:
The first draft is in PSD format and the final draft is in TIFF
Step-by-step explanation:
PSD is the automatic file format as you save any file that has been created or edited in Photoshop, this kind of format allows to save a file with a maximum size of 2 GB, therefore the final draft is in TIFF is it offers not only flexibility in graphics and sharing files between different types of equipment, but it also provides a bigger range of GB to be saved, as we can see that the final draft overpasses the 2 GB the most logical option would be TIFF format.
