This is my personal favorite fireplace picture. The ISO was 80, the Aperture f/2.8 and the Shutter Speed 1/200.
It doesn’t look like this if you will make the picture. After that you will have to work on the shadow on a program, you can use Photoshop or even iPhoto for this. Just change the shadow from 0 to anything you like and it will surprise you what nice effect it will give you.
Try it on your own!
