In order to make use of your research in an acceptable academic format you will need to be able to effectively acknowledge where your research and the ideas from your research originally came from. This is where the use of quotations, images, paraphrasing and summarising is crucial to your research. This is not only essential for academic writing but also for your research for studio. How do you know that the work you are creating is valid or is acceptable? You may not always be aware of all the research that you do, but it is reasonably safe to assume that your ideas are generated in response to what you make, read, write or experience. It is essential that you effectively reference and acknowledge what has shaped and influenced your ideas.
It is often assumed that references are only required for direct quotations. Remember that the idea of effective referencing is to ensure that the reader is aware at all times of which sources informed your research, ideas and writing. Arguably most of your footnotes will refer to passages in your text where you have paraphrased or summarised what you have read or experienced. Even when you are using your own words, you need to acknowledge where the idea came from. Direct quotations should be used for a particular function in the same way as you might include an image to demonstrate, illustrate or support your argument; a direct quotation should normally have a function or be included for analysis.
