I don’t really want to spend £100 or more for the calibration device and what I was hoping was that if I do just some rough versions people would pick up on the general sense of direction.

I do understand though what is being said but I was really hoping that it would be a bit simpler in interpreting roughly i was trying to communicate.

At work at the moment waiting to do something but If i get one I will try to get a cheap one because I really don’t see too much worth in roughly looking at something and trying to communicate where I feel the faults may be for £100.

Can you see my point on that?

I kind of feel that budget to communicate with some still images is fairly high priced when I would also still not be saying this is exactly how it should look but trying to find guiding principles or patterns.
