Below are some visual examples of the described issues. Example of pollution on camera sensorīesides dust, issues can also stem from scratches, canned air, or traces of dried cleaning liquids that negatively impact the sensor and cause compromised images. You can clearly see dust spots and lint in the marked areas. Below is an example of a cloudy sky, which shows a lot of dirt. When this dirt becomes visible in the recordings as disturbing artifacts, we call it “dirt on the sensor”. Every time the lens is changed, there is a chance for dust, lint, moisture, sand, or other particles to get into the space in front of the sensor. So, let’s pick Gregor’s brain to get you up to speed with handling those dirty sensors! Dirty talk: Dirt on Sensor, what is it all about?Ĭameras are often used in dirty environments and have to withstand a lot. For example, he has experience as a Digital Imaging Technician on set, used to be a workflow supervisor in post-production, and worked as a test manager for a large camera manufacturer. Gregor has been working in the film industry since the transition from film to digital cinematography (anyone else remember the Arriflex D-20 and RED One?). This article was contributed by guest author Gregor Baumert, a former test engineer for all software products here at Pomfort. So, how do you do that? In the following, we will outline how to check your sensor for dirt using the Pomfort grading tools and also provide useful background information on soiled sensors and related consequences. To avoid costly retouching in post-production, it is recommended to regularly check the state of the sensor protection glass and clean it if necessary. In a recent blog post, we already provided an overview of how to prep your Pomfort applications for the first shooting day. This article extends those tips by looking at a very specific prep activity:īefore a production starts, it is important to test the camera together with the camera department – in particular, whether its sensor shows any defects or dirt. Prep work is an integral part of the DIT’s responsibilities.
