I'm trying to calibrate my monitors. But I'm wondering if I can avoid buying another piece of equipment by using a lab spectrometer (in the past I've always just calibrated by eye). I'm a PhD student doing astrophysics, so I could almost certainly get access to some very good, lab-grade spectrometers. I actually have a lot of friends in optics in my department, so I can probably borrow something useable.
My question is how would I go about calibrating a monitor using a spectrometer without any software to make it automatic? My first thought is to just open Photoshop and make an entire canvas of perfect red, then green, then blue, and mess with settings until I get the best match with the spectrometer for each. But I feel like there must be a more straightforward method, instead of just randomly trying different settings until I build some sort of intuition.
Has anyone tried to do this before? I'm really curious to try this, not just to save money, but because I think it would require me to have a much better understanding of monitor calibration and performance. So if anyone has any ideas of where to look for good information to help with this, I'm all ears. Having access to this kind of equipment really makes me want to try going all out with this.
