That's pretty much what happened to me as well. At first they wanted their standard fees per photo of £40 for the first, £20 for the second and £10 for any after that. Those fees were terrible, and I was successful in getting a lot better rate. I ended up waiving my unauthorised usage fee and setting for a a reasonable amount that I would have been happy with if they had contacted me in the first place. Still, several people are saying that I should have stuck to my guns and demanded my original invoice and that I was too lenient. Perhaps a learning experience for me...

I was also successful in getting a better rate, but I invoiced very high (£1k) and negotiated down to a reasonable rate for both parties, but I was told afterwards I could probably have pushed my luck.
