While it is obvious you must have your photography galleries ready for uploading to a site, there are other things that you must prepare as well. Plan to have an artist statement ready, which is simply a statement about why you choose to do what you do. There are several components to an artist statement which include a brief statement about your work and your approach to your medium. It should compel someone to want to look further at what you do, so make it brief and enticing. Write it in the first person with two to three paragraphs. Let it change as you change; but initially write it using descriptive words to provoke further looking into your site. Consider writing more than one for different bodies of work. Write it then set it aside and come back later after you’ve worked on your photographs for a while and have a trusted, honest friend read it to give any insights they might have for you. There are several good resources online to creating one. This is the one I found most useful: http://bit.ly/3pbQT
The other document you should have ready to go is a brief bio of yourself, a short paragraph or two is good. This should be brief stating who you are and what you do, if you want to include or have any awards or accomplishments to entice people to want to use you and your work, do include those as well. If you have the capability and want to include a PDF file of your resume’ onsite you could do that as a download, but I wouldn’t suggest you put that directly on your site. I would have one ready to send to a potential client if they ask in PDF or as a doc. file.
