It is vital for most visual artists to have good quality photographic prints, slides and/or scans of their work to use for self promotion (portfolios etc), grant applications, reproductions in magazines and books, slide libraries, gallery records and insurance.
It is essential that these images be of the highest possible quality to fairly represent your work. You can either employ a professional photographer to carry out this work for you, or if you are sufficiently confident and can obtain the right equipment, you may be able to do your own documenting.
