[QUOTE="Dihusky, post: 428723, member: 10304"] Gizmo and Wally69 are in principal spot on, unless you lock the colour balance of the environment and maybe the settings in the camera/phone, you will get a variation. This is not only influenced by the background but more importantly by the light source. Daylight is generally considered to be 5600K (degrees Kelvin) but can vary, bright sunlight can be up to 9000K, LED can be either 6000K, 4000K or around 2800K often referred to as Daylight or Cool White, White and Warm White, tragically there is no standardised description between manufacturers, halogens and incandescents are all around 3200K. Fluoro lights are a world of their own and can often throw a green colour cast in pictures. If you phone is set for indoors, the internal (software) preset is around 3200K so if the stone is in daylight it will hold a very blue colour cast, if the phone/camera is set for daylight and the stone is indoors under artificial light then the stone may have a very warm colour cast, depending on the type of light source. You can correct the colour casts in photo editing software, but they are rarely as good as a natural photo taken with the right settings, oh and flash is daylight. Mate, it's a bit to get your head around, but that's it in a simple nutshell. I'm used to dealing because I'm an ex cameraman & still photographer. As you are photographing stones regularly, try and work out a standardised setup for your pics, then a quick play with your phone's settings to find a combination which gives you results you are happy with, it'll be a lot cheaper that a camera and macro lens!
