If the cycle is:

1 photographer uploads photo;

2 photo consumer (e.g., magazine) pays USD to Kodak for photo usage;

3 Kodak pays KodakCoin to photographer;

Then it looks like a cash grab and the chances of success may be limited because there is no demand driving the price of KodakCoin.

If the cycle is:

1 photographer uploads photo;

2a photo consumer buys KodakCoins from exchange;

2b photo consumer pays KodakCoins to Kodak for photo usage;

3 Kodak pays KodakCoin to photographer.

Then it may be viable because requiring the consumer to purchase coin creates demand for the coin.
