Process consistency with regards to illuminant, lens, exposure, raw
processing, any other processing, etc. is crucial for shooting the multiple
targets used to build the input profile...
AND equally crucial when actually using the resulting profile.
There's a lot that can go wrong if you aren't meticulous about process
control!

Yes, since building my last chart, I've come to realize that it's a much
better idea to make many small charts for camera profiling rather than a
single big one.
Care is needed in choice of illuminant, as well as maintaining consistence
across both exposure and development. Unless you're photographing the charts
in immediate sequence, you're setting yourself up for an extra helping of
fail.
