Reading the competition rules I have no idea what this means "Please ensure your JPEG image uses the sRGB colour space as all metadata will be stripped from entries". I do not have Light box or Photoshop. The only software I have for post production is what came with my Canon. I have no idea how you can tell whether a JPEG image uses the sRGB colour space, probably because I have no idea what all this means anyway lol. Can someone please help.
