This is a rare natural phenomenon known as a rainbow cloud or fire cloud. I photographed it last July from Bukit Beruntung near Federal Route 1. It was my second time seeing and photographing this beautiful weather phenomenon. The first time was from the old Bentong road.
I discovered something new when I re-opened the image in the updated Photoshop software today. Rainbows and cloud rainbows benefit greatly from the new Dehaze filter in Photoshop CC 2015. The rainbows colours became more vivid and clearer when Dehaze was deployed under Camera Raw Filter.
With another image of a regular rainbow arc, I was able to bring out the so-called double arc or secondary rainbow that was otherwise invisible. There is payload though. It is at the cost of noise increasing in the blue spectrum, especially that of the sky.

Adobe announced a major update to its Creative Cloud subscription service last night. Photoshop CC 2014 became Photoshop CC 2015, and included with it are several useful new features.
One of the new features that caught my attention was Dehaze. I downloaded the new version immediately to try out Dehaze. Well, not as immediate as I wanted; for the update process was a bit clunky and took a while.
You have to update the Creative Cloud Services first, Then download the big install of Photoshop CC 2015 (and Lightroom). Copy all your plugins to the new folder and download, reinstall the latest Camera Raw.
Yes it can get ugly; so here’s a quick and dirty demo for those who don’t have the patience, time or a fast internet connection. Haze can now be easily removed or reduced with a simple slider in the Camera Raw Filter. It can add haze too, if desired.
As you know, Malaysia has one of the worst haze occurrences thanks to a leaky neighbour. So the true test of the Dehaze slider, for me, is whether it can fix a picture fogged up by the transboundary haze or smog.
I ran a picture from the last bad haze day which that was captured in October 2014. The original picture was photographed in RAW and I opened it directly in Photoshop.
For a different comparison, I included another picture with organic haze or mountain mist photographed at the Genting Highlands resort.
