... Wow, I must admit that I have seemed surprised by your patronising replies in the past...
Why surprised? I worked hard to build a reputation on that
... giving away images to educational projects is simply right...
And once again, where did I say it is wrong?
... I thought the topic of the thread was "should I give away my photography for free"? I have no idea what you think this thread is about!
My first post in this thread was a response to a specific comment, which I will repeat here:
...a photograph can often be a gift that will be valued by the recipient but costs the donor little.
I responded to that specific combination "valued...but costs little." with a general statement about the perceived value of gifts. If you, or others, are willing to discuss that, I am all for it. I can then cite scientific research I am basing my opinion on. If your only contribution is getting on the high horse of righteousness and moral superiority, then, yes, I am inclined to respond with sarcasm.
