Hi guys, a friend suggested I join the forums to ask for some more info about this Cloud I saw the other day..


BIG http://farm1.static.flickr.com/228/524697874_dec23d4e60_o.jpg

this is looking out my office window in chatswood, nsw. 11th floor, the glass has some tint, but its NOT polarised.

i then wen t down to the street to get a better view

while not as striking, its still got some colour in it.

the sun was almost directly left of this cloud.

the images are unedited Jpeg files from my canon eos 1d mk2 and 70-200 lens.

anyone know what they are, whats causing it>? would be great

thanks
