Is it a historical photograph or a photograph published in a book that someone scanned and posted on line, is it a photograph of something like a sculpture? Is your paper focused on the work of the photographer, the makeup artist who prepared the model, the digital image enhancer who altered the image, the model? There is no single correct way to cite a photograph, because there are many different reasons to cite a photograph. Your instructor would be able to give you more specific advice. In general, though, the 8th edition of the MLA guide would say something like this:
Direct Quote : A direct quote is when you use another persons words directly in your paper. Knowing when to use a direct quote is important. Do not quote everything you want to say. Most things should be paraphrased. Use a direct quote when you want the reader to read an important historical line or it is something someone said that is important. Use direct quotes sparingly, there should only be a few in the paper and they better be good ones. The key difference in citing a direct quote is that you must put quotation marks around the sentence and then cite at the end. IF YOU FAIL TO USE QUOTATION MARKS AROUND A DIRECT QUOTE YOU ARE SAYING YOU WROTE THE SENTENCE. THIS IS PLAGIARISM!!! More information on direct quotes and direct quotes over four lines to follow.
Format for entries: A single space is used after any punctuation mark. When dividing a long word or URL onto two lines, put hyphen, slash, or period at the end of the line. Do not add a hyphen to a URL that was not originally there. Never begin a new line with a punctuation mark. Double-space all lines in a bibliography entry. Do not indent the first line of a bibliography entry, indent second and subsequent lines 5 spaces, or 1/2″ ( cm) from the left margin. Please see Chapter 11. Guidelines on How to Write a Bibliography for details.
