Clown smile Rock at Bodice Cove, Maine. From yesterdays bug-out to Corea Maine.

So check this out: this morning I couldn't sleep so decided to get out of bed at 03:30 and checked the sat maps and the sky was clear and boring, so instead of photoing did a bunch of spring cleaning of the hard drives and deleted a thousand images that were really unnecessary and or lame. In the process of said spring cleaning: checked the old emailerino and in the headings there was a rare potential customer, probably another "I saw your photos and loved the one of "blah blah blah" and how much for a print, wherein I reply with my modest rates and a quick explanation of the process quality and attention to detail and expensive museum quality materials etc and I never hear from them again. But surprisingly this one was more complicated, and not just a "will you make a donation of a print to...", this one was from our most favorite of computer companies in the world and they were inquiring about an image to license for a future project and here's where it get's really challenging. They expressed the desire to license a pretty good photograph of mine (reads: one that I like A-ok and isn't just a "go there and get it kind of thing") Here's an excerpt:

 "We are interested in speaking with you about possibly licensing the image attached.  At this point, we are in the early stages of our research, but would like to include this image with our next presentation.  The rights for usage we would require are:  Worldwide, unlimited, non-exclusive, used as a desktop or screensaver option.  Image or images will be imbedded in our products and sold pre-installed in the software. Duration of license is 5 years. (timeframe is negotiable)" 

After another email it was plainly put that I could still use it personally however I may desire (my main considerations are to print them for local galleries, etc, you know to have it as my art or whatever) but herein it became complicated and therein is todays lesson of the day: trust. I didn't know what all to tell the fellow regarding the perceived value of said image in this capacity. I could have asked some acquaintances for their opinions but in the end I remembered somewhere that if it's a seemingly reputable organization honesty may prove the most valuable format. There are softwares like Fotoquote etc that will theoretically come up with values and other methods to determine the potential value of commercially used artwork but after an hour or two of thinking on it subconciously I decided to write this: 

Great [persons name]- I'm definitely interested in licensing a photograph to (greatest computer company in the world). That would be Great-Skates! See here though- that is one of my more fond images and I would only be interested in collaborating if I was properly reimbursed- I'm certainly not very familiar with appropriate licensing values but I do have a particular taste for this one that I would like to achieve at least three figures. Could you advise me honestly as to the value you perceive the image at?
