darkosaric: I started at age 14 (1964) if you want to update your list.
Honestly, your Excel worksheet provides data for real value in this analog/digital determination. There are many ways of massaging this data and maybe you should consider listing the data from youngest to oldest (or oldest to youngest). But, also, your second column stating WHEN the person adopted film is highly relevant as well. A person who is older and JUST started with analog is interesting. The fact that film 'won' this person over recently is highly relevant to our survey; merely stating how old one is NOW becomes even moot at times without the other data.
There are many different ways of determining just how popular film is NOW and how important it will be in the future. For example, one is 'why' still film. Economic or otherwise: film is cheapest to START with (if you do not have the necessary technology at your ready and convenient disposal). Also the psychological 'comfort' of seeing your capture in the form of a negative I think has the MOST to do with why I cherish film so much. As analogy, if I were to take a far away trip, say to Europe again, I would bring travelers cheques because I want to 'see' how much I have instead of 'trusting' a computer to read me the (hopefully) correct dollar balance or even 'swallow' my debit card. Also, I would not have to worry about the card not being accepted. (NOTE: I do know that some banks now will not accept them but there ALWAYS is somewhere to cash them, even if at American Express.)
Many will find that assessment funny, quaint or other but, to me, that is a real issue. I simply cannot adapt to 'knowing', in the form of 'digital trust', without seeing first hand. I feel the same way about traveling in an automobile with GPS navigation. I despise this method and need to first Google the address map so that I see the entire grid in my mind. I, then, can easily find my own best route with ease. I hate going step by step without seeing the entire picture beforehand. That is just the way I think and I get terribly confused otherwise. Place me in a strange city with a good map and I will be happy and content and never afraid. At 20, in 1970, I went to Europe alone for six months and enjoyed each and every minute. Darkosaric, I even visited relatives in Wolow, near Wroclaw Poland!
I also envision analog manufacturers gaining practical insight from this survey. - David Lyga
