When I first started I asked a very experienced photographer about getting credit. I had a big job in New Orleans for some very snazzy hotels on Bourbon street. The company that hired me wanted to put the hotels logos on the tripod caps leaving me with no credit. I was not sure I was going to take the job becasue of this.
He said without hesitation "forget the credit, take the money" and went on to explain that I would have plenty of time to "get credit" and if I did a good job and made the client happy thats all that mattered and I would probably get plenty of business from them.
So I took the job. I did get credit on a single web page buried inside my clients web site after I had to ask about 10 times to get it. After about 2 months they took that off too. This client then proceeded to say they "produced" the images and used my work to start their own virtual tour company. Yes a huge viloation of copyright and numerous other laws. But I did not have the resources to sue and besides it would not have mattered anyway.
Of course I did not get any new business from this deal as I had hoped. This was 5 years ago when panos were still kind of new and no one had them on Bourbon street. I had hoped for continued business from this client. I was counting on it.
After this incident I never agian sold a pano without my logo on the tripod cap. I don't even bring it up with new clients.
For lower priced tours it is not an option. If they don't want my credit there I don't do the job.
I do share the tripod cap. I put my phone number and name around the edge and put the clients logo in the center. I don't charge for this because my credit is there also.
It is common practice to charge around $50 dollars for a logo placement on the tripod cap for basic real estate tours. But your competitors might just include this with their tours so you might have a problem there.
For higher priced tours this becomes a more delicate matter. I have had a few clients who wanted their logo without my credit. I have to negotiate this issue with them. They usually understand my position. In every case I ended up sharing the tripod cap with the client.
So far non has actually demanded my credit appear no where in the image. I can say that if this ever happens I would probably charge about 50 to 100 percent more for the job. But in this scenario the client is most likly going to use the images for a CD marketing campain or distrubute the images via stand alone viewers etc. In this case the price would be greater anyway due to the inteneded use of the images and I would get credit somewhere in the CD or other appropiate place.
I say charge $50 for logo placement on a $100 dollar 4 image tour. On the higher end stuff this becomes a matter of "image use". If the client is willing to pay for "unlimited use" then they can have the tripod cap but I will demand credit somewhere acceptable to me. And thats in the sighned contract this time!!!!!!!. This old dog only has to bite that frog once to learn his lesson. LOL.
