Your first mistake is to give a damn about what other "...photographers themselves don't accept digitally..."
Exactly.
Whilst an audience's actions/reactions will inevitably have an impact on how you work, the best way to look at it is that you are doing what you do best. Whilst an audience's response to you work is of obvious importance, it shouldn't be deciding factor in your creative decision making.
BUT If you want to look into WHY it is in fact your duty as a creative individual to go against that viewpoint, there are a few things you can read:
Gerhard Stäbler's 'Sharpened Senses : Open, Responsible, Challenging : Composing Now'
- he's a New Music composer who talks about resistance to his work (in a surprising number of ways), but argues that whilst resisting change is a natural instinct, truly innovative work (even if seen by some as 'offensive') creates room for 'exposing... uncertainties together and viewing the resulting tasks as provocations in the positive sense, and encountering previously unaccustomed, unknown, even existentially challenging situations with creativity'.
Its a bit of a heavy read, but its great motivation to carry on past any negative responses you encounter as an artist.
A nice easy read is Johnathan Burrows' 'The Choreographer's Handbook' - just the first 40 pages (it sounds like a lot - its not - the text is so spread out and there are bits that don't really matter too much so you will finish it in under 15 minutes, I guarantee).
That excerpt playfully looks at how we can explore new possibilities in art (it is about modern dance, but most of what J talks about is applicable to all art forms) - it takes all of the built up huff-n-puff out of the creative process and just gets down to what things you need to consider when creating.
Just remember to not take anything anyone says about your work too seriously. Yes, your work matters, but every so often just step back and say 'its only a fucking picture'.
P.S. if you want an example of someone who creates digital artwork from photography look at Michael Najjar's series of mountain ranges as stock market infographics.
They're called 'High Altitude' - just look at them in Google though - his flash website is useless.
