I don't get the point of this video - what is the advantage conferred by Camera here? I use Excel's Camera function extensively but how is this different from copying an area of the sheet and just pasting as an image? The point of Camera is its dynamic updates, which are totally lost outside Excel.
The point is to set up your image once (size, range included, etc.) and then easily copy-paste it whenever data changes. For example, I have a monthly report in PowerPoint that includes 20-25 tables in it. I have the images for these tables set in an Excel file, and whenever I update the data and calculations, I only need to copy-paste the updated images, and they fit perfectly.
