1 MB, 1520x2688

quick question for the techy people, does it take longer to compress a large image for example 5 gb into 2 gb or would it take longer to compress 5 gb into say 4.5 gb now it might seem an obvious answer but for a piece of coursework at uni i had to time how long it took to compress a file into different file formats. (i have exaggerated numbers here for the sake of an example) but part of my project is to take a RAW image and render it down to a lossy format such as a gif or jpeg. (pic isnt related)
