Use a tripod, if outdoor toss a bean bag over the top also ...... & try using a delay on the picture your taking because it moves after u press the button. Most of the time the auto white balance works indoor but your better off getting a white balance cap that you can use outdoor. The white balance changes fast when the sun is coming up & setting.
If you use post processing like photoshop, read your colors in the white areas ( color sample tool in your pallet the eye dropper tool ). Lets say your yellow is off, it will be reading 10% in your white area this throws all colors off in your image, greens, blues ect .....Go into the curves pallet its c,m,y,k and choose y ( yellow channel ) and pull the mid tones down ( center of graph ) until it reads 3% in your white area for the yellow.
The red & blue should also be 3% in your white areas. Black 5% or your whites will have no detail or if your whites do not show black it means its washed out and all and all a bad pic because the black channel holds the details of the image. So you can fix any image by making sure the yellow, magenta, cyan read 3%. ( i do all my color work in c,m,y,k better control than r,g,b even though rgb is better quality. I work in c,m,y,k then convert into rgb before i save out ..... )
But ya the money is made in manual mode & with a real nice lens, not the kit lens most come with.
I could go way more in depth on color theory or more photoshop tips. I ran a drum scanner for a magazine house & started in the beta version of photoshop in the mid 90's.
