Hello everyone,
Would like your help with monitor gamma calibration:
Does anybody have a script that helps doing gamma calibration manually with a photometer (grayscale, not colors), and creates a gamma table which can be used in experiments?
I created a script with GPT, did a calibration with a photometer and got gamma value of 1.98. when I use the gamma table in my experiment, the the monitor seems much brighter and the stimuli are harder to distinct (it seems like the contrast decreased). Does it make sense?
Thanks in advance :)Hello everyone,
