Good stuff, TOM. That said, if you post one more comment regarding "aspect ratio" I will fly to Cali and give you a wedgie. Cheers!
Actually I just now deleted the other video about aspect ratio. I realized it didn't get across why it's so important. I then searched through YouTube and I could not find a video that does. I'm afraid I'm going to have to make my own. However it will not be anywhere near the quality of John Hess's videos. For those interested his explanations about such technical aspects of film as middle grey, contrast ratio, depth of field, lighting, etc. are simply mindblowing.
