How to make a truecolor tif from arrays

Hi, I want to make a tif image, truecolor MxNx3, from arrays. I can see that it is possible to do this where each color is of a value from 0 to 1 but when I read in a tif image I see the uint8 0 to 255 values. I want to understand tifs better and want to be able to isolate a single pixel and see its value(s), and relate that to the values for the same pixel when the tif is split into the three RGB layers (have I worded this badly?).

The question is not clear yet. What are your inputs? "From arrays" is not clear enough.

Colors can be represented by double values in the range [0,1] or UINT8 values oc [0, 255]. You can simply convert between the two methods by a division and casting to the wanted class.

Hi Jan, I wanted to generate some arrays/matrices and play with some aspects of tifs. All the arrays for this purpose are self generated, they have not come from an image.
