guidelines for taking pleasing photographs

Explanation:

guidelines for taking pleasing photographs – this is the right answer. The ideas that are appliable for other forms of visual art are also crucial for quality photography. When studying what the major guides for taking pleasant photography are, we must consider common principles of design, such as composition, planning, proportions, colors, themes, etc. All these elements of art are what make our photography excellent and enjoyable.

automatically included in every picture taken – this is not the right answer. There is nothing specifically in photography that makes it automatically well designed.

principles that apply to photography, but not other arts – this is not the right answer or statement. Principles of design and elements of art are included in all kinds of visual arts.

complicated concepts used only by professional photographers - this is not the right answer. Amateur photographers can also learn and use principles of design in their work.
