Could someone please do some photoshop magic and show the actual difference between the 3 maps please? I would, but I don't know how to use Photoshop. [[User:SqueakSquawk4|SqueakSquawk4]] ([[User talk:SqueakSquawk4|talk]]) 10:20, 2 January 2023 (UTC)

:In what way show the difference? Overlaying is easy enough (for two maps cut rectangles, paste as new layers moved atop the third (use transparency as a guide), then either twiddle the transparencies to make it look informative whilst static or make them all backbto opaque but use layers as animated .gif frames, suggesting 1000ms rate or thereabouts), or at least it is in GIMP - not used Photoshop for years... Maybe a decade, but I bet it's almost the same.

:Alternately, slightly more complicated is to translate the white-to-red colours to some monochrome shade (white-as-#000, red as #FFF, which can probably be done by isolating a given RGB component; but preserve/extract the black lines as a separate overlay for later) and then use them to govern R, B and G channels (again, easy in GIMP), combining them together to give greyshades where equal or colours where the intermediate levels 'disagree' either in one (vs the other two) or even across all three.

:Would try either, myself, but I don't have upload ability and it also needs me to be on my desktop instead of this tablet. So I'm giving you (anyone) my likely methods. [[Special:Contributions/172.71.178.65|172.71.178.65]] 13:53, 2 January 2023 (UTC)
