Q6. A camera can take digital photographs with pixel dimensions of 3264 2448 pixels.(10 points) Part one. What is the resolution capability for the camera? Show it with the mathematical formulation. Part two. What is the physical dimension of the printed image if the image is printed at 300 ppi. Show it with the mathematical formulation.

Q7. Suppose you want to scan part of a photograph to use in a digital collage. The part of the picture you want to scan is 2-inch 2-inch on the photograph. You want this scanned piece to appear as 6-inch 6-inch in the final collage that will be printed out at 300 ppi. If you scan the picture at a resolution insufficient to print it at a size of 6-inch 6-inch at 300 ppi, you will have to scale up the scanned image, which will deteriorate the image quality and make it look pixelated. What is the minimal scanning resolution (dpi) you should use to scan this 2-inch 2- inch area so that you do not have to resize the image to meet the printing requirement? Show your calculations. (8 points) ( Hint : First calculate the pixel dimensions of that piece of image needed in the final colla
