WU; Calculating file size- You are given a full color photograph, 24 bit which is 1024(h) wide by 768 high(v) What is the file size(number of pixels)? ____________ What is the raw file size ? _______________ Calculate the raw file size in bytes _____________ Calculate the raw file size in kilobytes _____________ Finally how big would the image be if it was printed on a 600dpi printer? ___________________________________________________

Calculating File Size Calculating file size- You are given a full color photograph, 24 bit which is 1024(h) wide by 768 high(v) What is the file size(number of pixels)? 786,432 What is the raw file size ? 18,874,368 Calculate the raw file size in bytes 2,359,296 Calculate the raw file size in kilobytes 2359.296 Finally how big would the image be if it was printed on a 600dpi printer? 1024/600= 1.706 “ 768/600=1.28”
