An area of my film where I strove to achieve realism in as many aspects as possible – including texturing, lighting, colour and environment – was the depiction of the inside of the intestine. In this scene, I recreated the appearance of colonoscopy footage as the camera travels through the body to show a healthy portion of the intestine compared to an area affected by Crohn’s. This is to highlight the severity of the condition and allow the audience to understand the internal physical effects of the condition and not just the exterior symptoms. So, why strive for a high level of realism in CGI rather than use live footage of these internal processes? I conducted research into the information already available on colonoscopies, and the visuals used to aid this. As colonoscopy is an area where footage is easily captured, most the visual information was live action – but as with surgery scenes, this could be considered uncomfortable viewing for an audience. I then discovered an animation by Nucleus Medical Media, which uses CGI to explain how a colonoscopy is performed and its uses. Initially, we are shown a transparent view of the intestine’s exterior as the colonoscopy camera travels through the organ. The scene then cuts to show the internal view of the intestine – the model is created to replicate realism as best as possible, but the environment is clean, and visibly still Computer generated.

When creating my own work, I considered that I could use the same techniques for these shots and could also create a cleaner, less gory overall appearance of the anatomy. This could present more comfortable viewing for the audience, thus encouraging them to focus more on the smaller details. As with Nucleus Medical Media’s film, animated footage could also allow me to manipulate the camera movement so the scene initially portrays a shot of the intestine’s exterior before travelling internally – this allowed the audience to immediately recognise which part of the body was being explored.
