      Great B&W’s Richard. I must say the ir technique does make the appearance of the cirrus more thick than it might have been, but it is cirrus in both cases. The fist one may be cirrus floccus. The second one shows two large patches of cirrus. These might be cirrus spissatus but here the ir may be too deceiving to interpret.

      Any other opinions?

      thanks, hans — you make a good point about the ir effect that i hadn’t considered before …… it appears that the ir picks up more of the ice crystal reflections that we can see with the naked eye, thus ‘thickening’ its appearance, as you say

        I agree with Hans on both. I also wanted to add that IR makes the sky darker, actually very dark. That’s  because the blue light, which is scattered by the air and gives the sky its luminosity, if cut out by the filter IR filter. So that results in greater contrast.
