Recently, I shot a couple of pumpkins in RAW format. The size of each RAW file was around 25MB. Then I converted the RAW to JPEG and deleted the RAW files. Now I am wondering if I need to retain the JPEG at its full resolution of 5184 x 3456 (17.92 mega pixel resolution) (~6MB each file). It is not like I am going to print the images at high resolution. It may be prudent to reduce the image to 25% its original size.
