The process of reviewing the prose for specific style rules, such as editing the technical aspects of the text including capitalization, spelling, punctuation, indents and spacing, paragraph & chapter structure and other stylistic rules.
Substantive editing looks at the actual story behind the text. The editor may dramatically change the structure of the text to address big-picture issues with the prose.
Included for completeness. Image and photo editing are outside the scope of an editor, and are in the realm of the graphic designer and artists. We suggest engaging a qualify graphic designer to help with your graphics, images, or book covers.
