In the realm of videography, one can truly appreciate the profound interplay of art and science, the function of aesthetics underpinned by the theory and practice of technology. The videographer's role, akin to a modern-day alchemist, is to transmute the mundane into the extraordinary. As we embark upon the path of sourcing a suitable videographer, it's essential to undertake a journey of inquiry.

The first question to pose is, "What is your experience in the industry?" A seasoned videographer, having weathered the vicissitudes of technological advancements and shifts in aesthetic sensibilities, can bring a wealth of knowledge and dexterity to the project. While years do not necessarily equate to expertise, they do offer a basis for determining the videographer's ability to navigate and adapt within this dynamic field.

Secondly, we must probe into their knowledge regarding the latest in video technology. The field of videography has not been impervious to the relentless march of technology. The advent of drones, VR, and 360° videos have revolutionized how we perceive and produce video content. An adept videographer should not only be familiar with these tools but also demonstrate an understanding of how and when to optimally deploy them.

Thirdly, ask about their style and how it complements your vision. Videography, like all art forms, is idiosyncratic. It's a manifestation of the videographer’s unique lens through which they perceive the world. This unique perspective can either harmonize or clash with your envisioned outcome. It is thus paramount to ensure stylistic alignment.

Next, inquire about the videographer's pre-production strategy. This process, often overlooked, serves as the linchpin for effective video execution. From storyboarding to location scouting, the videographer should have a meticulous plan in place. The technique of previsualization, derived from the cinematic practices of Alfred Hitchcock and Ridley Scott, can be an effective tool in this stage.

The fifth question to consider is their approach to post-production. This phase transforms raw footage into a polished final product, invoking elements of color grading, sound design, and special effects. To quote Orson Welles, “The whole eloquence of cinema is achieved in the editing room." Thus, understanding their editing prowess can provide insight into the final product's quality.

The sixth question shifts the attention to the investment: "What is your pricing structure?" The economic theory of Cost-Utility Analysis might be applied to discern the value proposition offered by the videographer. By evaluating the perceived utility or satisfaction derived from the video against its cost, one can ascertain whether the investment is justified.

Seventh, ask about their project timeline. Punctuality and adherence to deadlines is a crucial determinant of professionalism. By utilizing Critical Path Analysis, a sequencing technique used in project management, one can assess the videographer's capability to deliver on time.

Lastly, request to see their portfolio to assess their body of work. This visual resume offers tangible evidence of their ability to articulate a narrative through the medium of video. It is the videographer's opus, epitomizing their unique blend of technical prowess and creative expression.

In conclusion, the videographer’s role, while primarily artistic, is deeply rooted in a scientific and methodological approach. Through these eight queries, you are not only vetting for technical competence and creative flair but also their strategic thinking, project management skills, and adaptability to technology. These inquiries will serve as illumination on your path to finding the right videographer, an alchemist who can transform your vision into a visual spectacle.
