Great Info Dave! Thanks! Yea all “light” is energy. Our eyes/brains see only a portion of it. Shooting IR takes a lot of trust!

Lisa, I think as close to an Overview you’ll find is..cloud should part of a discussion or exhibition. The site is International so a decorum is subtly implied. But there are no hard rules besides adhering to our manifesto. One thing tho..I think is still in place..is the instance you post creative content, here, its copyrighted. Thats true at any Internet Site. Can you post your work at multiple sites ?yes. Can sites do what ever they want with your work? Not with out your permission. Yes a photo of yours can be in the Gallery and you can post it in a forum.
So, another approach to the Freedom we are allowed here,,is a personal plan. Do you have a library of shots you want to share? Do you have a style you want to explore and express? etc. How much time a day or a week can you afford to posting at CAS? etc..We are quite free here to post our creations. Quite free to discuss technical scientific etc aspects of cloud. Yes, that freedom can be intimidating or just put aside as one enjoys their chosen way to express an appreciation of Clouds.

Dave, The thing about IR photography that always confuses me , is that you are photographing heat (brite) and lack of heat (dark). As you point out , normal dark can be brite if its “hot” as in the stop sign. Trees and grass are living things so they put off heat and of course are warmed by sunlight. Clouds exist because of heat. The more sunlit areas of cloud are going to be warmer so should be brite..which is a expected observation with visible wavelengths..So , with some objects the recorded image can be reverse of visible light and other objects the recorded image can be close to visible light image. Thats just for starters. Recording reflected heat or recording heat made by the object..in sunlite or in shadow,,I have enough trouble just dealing with visible light. I don’t know how you do it.
Terrain effects cloud formations. Hills and valleys can stir the atmosphere. Whats really weird is Asperitas over Antarctica or over Greenland. The one area I haven’t seen a pic of Asperitas over is…an Ocean..I m not saying Asperitas doesn’t happen over ocean,,Im just saying I haven’t seen a pic of it over ocean. Anyway, Im enjoying your IR photography. Can I ask what format is your camera and lens that you use?

Thanks Lisa! Leaving the bird in your photo reminds the viewer of scale, something I ought to do more often to be honest with the big sky out here.
Keelin, the rays really make your photo work,Nice!
