I don't think they are using Photoshop, but that would be hilarious :D It's just the camera sensor's color space (Adobe RGB). Anyway, gamma correction should be problem, unless they shoot raw images and in this case the color space gets out of the equation. I was curious, so I found another paper by the original authors and the color correction is more carefully considered, since they seem to take into account the sensor response too [0].

> Also, from their methodology and instrumentation (color cameras) it seems they could have done it in like 80s. Why coming out now? The 80s were mostly about DSLR cameras with film (whether colour or black and white). These three are currently focused on what can be determined from CMOS cameras using more recent techniques. eg: Meteor colorimetry with CMOS cameras https://arxiv.org/pdf/2106.07403.pdf treats digital captures as a limited range spectrogram in the visible spectrum normalises values and attempts to determine estimates for "the characteristics of meteors such as temperature…
