Step Two:
Right below that, it shows you the default settings for what kind of file it’s going to send over to Photoshop. By default, it sends a copy of the file over to
Photoshop in TIFF format, embeds that file with the ProPhoto RGB color profile, sets the bit depth to 16 bits, and sets the resolution to 240 ppi. Let’s start
with the File Format choice: I change mine to go over to Photoshop as a PSD (Photoshop’s native file format) rather than a TIFF, simply because its file
size is often much smaller but without any loss of quality.

Step Three:
Next, you can choose the Bit Depth of the file going over to Photoshop. If your goal is to maintain the maximum quality, leave it set at 16 Bits/Component.
The downside of 16-bit editing are: (1) some of Photoshop’s filters and features will be disabled (stuff like the Filter Gallery), and (2) the file size will be
approximately double (so a 36-MB TIFF becomes a 72-MB TIFF). Neither may be an issue for you, but I thought you should know. By the way, I usually
work in 8-bit mode myself.
