Halfplate transparencies approx. 165mm x 120mm in size usually contain a photograph of an engineering or architects drawing or plan, it can however contain other material. One halfplate usually contains an image of one drawing but also can contain images of multiple smaller drawings or pages.
DocuSense is able to convert your halfplate transparencies to a digital format. We use an optical enlargement technique during the digitisation process to enlarge the image back to it’s original document size for maximum clarity rather than directly scanning the original film.
Even if your film doesn’t look like our examples, our equipment and operatives are flexible and can capture most things. So if you have any questions, you can message us using the form on the home or contact pages.
