I just purchased a used Nikon SB800 flash and I have no idea how to use it. This is my first flash I have ever purchased. Since I purchased it used it did not come with any manuals. Nikon sells the SB800 reference manual for $9. I would like some recommendations whether I should purchase the reference manual from Nikon or is there another manual for the SB800 that is highly recommended?
I would appreciate any help.
