I am an undergrad at a local university, and recently a professor of my department is inviting me to take candid shots of the department staff 'in action' (i.e. during lectures), so that these photographs can be placed on the newly revamped staff website.
The professor said that on behalf of the department, I will be paid per quality photograph that the department chooses. The price, however, is up to me to quote. There are about 16-20 staff all in all. I estimate for each staff, I would have to attend one of his/her lectures for about half an hour to an hour to get a few shots.
As this is my first ever paid assignment, I do not know the 'market' of what I should charge per photograph piece. Yet, I want to charge a reasonable amount which will not underestimate my worth as a photographer nor do I want to take advantage of the situation that is before me (i.e. charge a high amount just because it is a university department).
I sincerely seek your advice, thank you very much
