Pixel Spreadsheet

When you take a digital photo, your camera measures the amount of red, green and blue light hitting each pixel, ranks them on a scale from 0 to 255 and then records those values as a spreadsheet. 2017 Festival presenter Matt Parker found a way to actually open digital photos as spreadsheets in Microsoft Excel or similar programs. Upload a photo and instantly download it as a real spreadsheet, and learn from Matt’s experiments!
