The term “digital filmmaking” can refer to a number of different processes and techniques used in modern films, and can simply mean the use of digital cameras, or more extensive digital aspects such as characters and environments created completely within a computer. Webcams are cheap and easy to handle but you should check that the specific model is compatible with your stop-frame software. T-Tests may show you that they are not significantly different, however, and you can’t base your conclusion on the means’ difference since the difference in the sample is not representative for the population.

Here are the rudiments of QA dose monitoring and follow-up: Recording of modality specific dose indices, associated equipment settings, and patient habitus, obtained, for example, from data of the DICOM radiation dose structured report. [As a modality-specific example, CT dose indices are standardized as CTDI and dose-length product (DLP), and they are based on measurements in standardized dosimetry phantoms. Photographers capture their subjects in images, and they must be able to evaluate the artistic quality of a photograph.
