Hi Rachelle,
Is your product photography part of other projects, or is it something separate?
We do all our product photography for each year in one project, each project has it's own issue. If every issue he needed to add more info to was in one project, could he be given more access to just that project to enter that info himself. Maybe create a View on the issue list so he could enter any additional info right there on the list of issues and not have to actually open each issue to enter data.
We have our photo studio coordinator set up as an Admin, only because when requests for product photography come in, there are generally SO many products that it would take forever to create an issue for each one. Instead I've created an Excel template for her, she copies the product info to that template and Kick-starts all the issues into Workfront all at once herself.
