Title: Ash Cloud Photo ?
Post by: JohnC on April 16, 2010, 02:24:51 pm
I was up with the lark this morning-5.10-am and took myself to one of our local hills and took this photo at 0633(sunrise was 0607). I'm only assuming some volcanic dust was in amongst the regular cloud.I had to use a 2-stop Grad. filter   due to the rising sun .

Great image from what looks like a quiet and peaceful spot.

That's a great image John and tempting to call an ash cloud, worth shooting it again this evening to see if you can get a repeat show, I have seen something like ash clouds here during the day around the Sun but didn't notice anything unusual about the sunset here yesterday, worth checking out again this evening. Lovely image by the way!

Yes,  a pleasant location,Richard - it's a golf course but at that time no golfers  but it's also public land and they don't mix too well,we had Ben the dog up there one day and a golf ball went inches past my wife's head (hit by a 14 year old out with his 'fun golf' playing family -  we didn't go again and in the local  paper this weekend a lady wrote in who had been hit in the chin with a sliced shot and the golfers just carried on, so, as they say 'something should be done about it'  one ot the  other but not both.

All a bit disappointing ,Martin. I think people were expecting skies like they have been after some of the other worldwide volcanoes.Turner's famous paintings  and Rembrandts for instance  which featured the multicoloured skies showed the world what Krakatoa (1883) did for sunsets.

Here's what Turner saw http://www.kenbushe.co.uk/html/colour_and_light_paintings_aft.html

I see that scientists are studying the old Masters to see the results of volcanic ash and also in relation to the global climate.

I think we need to give it a bit longer before we get something more than the subtle effects we've had over the past couple of days - get a bit more ash in the upper atmosphere etc...

Still a nice capture John  :)
