Anyways, back to my story. The message from said retailer didn't mention anything about 'buying' my image, just a request for the original file (photo below). I googled my way onto their website, and got punched in the face with their pricing - their dress shirts ranged from 115 to 450 Euros!! So I politely responded that I would provide them with a copy of the file for the nominal price of 100 Euros. Surely, an upscale purveyor of French fashion that felt right charging customers 450 Euros for a piece of cloth with some buttons and two sleeves sewn on it could afford to pay one quarter of that for a photo which would be used as promotional material to further increase the sales of their - did I mention the price of 450 Euros?! - shirts.
Well, turns out I didn't even get a response from them. My Ryan Gosling/ Fidel Castro-esque dream has been crushed, but I also feel good that I didn't provide my personal work for a "pathological profit at all costs, screw the artists" type of corporate entity to use in their advertising.
But still... feeling a little bittersweet at the moment. Having said all this, I'd still throw all moral qualms and principles out the window if they agreed to my (generous) terms. Vanity, eh?
