Hey Oliver
From what I have seen and observed, people who shoot themselves get more "trust" from their prospects. You know, they believe in real life and all.
Whereas, people who shoot pictures and powerpoint presentations seem more professional.
I can't tell you which is better, but you can try any!
TIP: Try mixing them together, like this guy is doing at http://www.autoclickprofits.com
Check out the video once you optin.
Thanks
