Hi cat. The burn tool can be accessed by pressing o on your keyboard. It is the icon right below the paint bucket/gradient tool. Just right click on it and select the hand. Then in your options toolbar set the exposure.
I find the burn tool very interesting, esspecially with black & white macros in conjunction with the shadow/highlight tool.
Be very carefull though, because just as easy as it is to turn a ok photo into aamazing one, it is to turn an amazing photo in a pile of .....
I did some testing on that photo of yours, I wasnt very successful as my boss does not like me doing personal things in bussiness hours :D
Atleast you can get an idea what I was talking about. I used the highlight/shadow tool to bring out some of the overexposed details more. Then I used the burn tool with an exposure of 20% and shadows to bring out the clouds more. Wish I had abit more time so I can mess about properlly :p
Another option is to use the burn tool on the buildings only and have a overexposed sky. That way the focus point of the photo is the buildings.
maybe something like this?
How cool! Thanks for taking the time to show me that - I love playing!!! :D
No problem cat.
