When you shoot in the RAW format, you must process the picture files in Adobe Camera Raw or Lightroom before they can be opened directly into Photoshop or Photoshop Elements. There is a tool in these RAW converters that I consider one of the great advances in photographic technology. It is the fill light slider, and it allows you to open up the shadows in a picture, thus revealing detail that was either very dark and muted or simply invisible because it was so underexposed. Sometimes black shadows contribute to the graphic nature of a picture, but most of the time the ideal is to reveal as much detail as possible throughout an image.
How far can you go in lightening shadows? Don’t you increase digital noise when you do this? The answers are you can go quite far, and yes, you do increase noise. However, you can mitigate the noise so it is basically irrelevant, allowing you to do amazing things as I demonstrate with the pictures in this article.
I took the picture of the ship I was sailing on in the Falkland Islands, above, as I was on my way down to Antarctica a year ago. My group had gone ashore to photograph rockhopper penguins, and we stayed until dusk. On the way back to the ship, I thought the vessel looked beautiful in the late twilight illuminated against the dark, cobalt sky.
To say the situation was dark, though, is an understatement. I could hardly see anything except the lights on the ship and their reflection in the surface of the ocean. I was in a dinghy bobbing up and down in the waves, and this meant that I was in an impossible photographic situation — too much movement in a very dark situation. I had nothing to lose by taking some shots, however, so I went out of my comfort zone and bumped the ISO to 6400 just to see what would happen. To be honest, I had never used an ISO setting this high before because I hate digital noise, and I thought the images would be totally useless. Even with 6400 ISO, my shutter speed was only 1/5th of a second with my f/4 lens wide open. I thought there was no way this could turn out to be a sharp picture, and at the same time I was certain the noise would be so large and offensive that I’d trash the images when I got home – or sooner.

I was both right and wrong. The pictures all had horrible noise as you can see in a small portion of the image captured at 100% magnification on my monitor, above. For my own sense of aesthetics, this makes the picture unacceptable. I wouldn’t want a print of it, and I couldn’t sell it. However, I was shocked that out of the dozen images I took, this one was surprisingly sharp. This was luck, not skill, because a 1/5th of a second exposure from a bobbing dinghy is a guaranteed formula for a blurred picture. Image stabilization would be of no help at all in a situation like this. I took the shots of the ship when we crested on a wave or when we were in a trough in an attempt to shoot with minimum motion. Still, I was really lucky to get an image that turned out to be fairly sharp.
Ok, so I had an underexposed picture of the ship with little detail, and the noise ruined the image even if I accepted the underexposure, which I didn’t.
When I opened the image in Adobe Camera Raw, I used the fill light slider to open up the shadows (knowing the results would be terrible), and you can see in the screen capture, below, how far I moved the slider to the right.

This provided incredible detail in the ship and in the water – much more than I could see with my eyes from the dinghy — but the digital noise became even more pronounced. In another screen capture, below, you can see that the price I had to pay for the additional detail was giant noise in the shadows, and the night sky, which now has great color and exposure, is so noisy that to make a print of this would be ridiculous. If I had a choice between showing a print of this to a client or eating worms, I’d take the worms!

Ok, here is where the plot thickens. To save this image, I opened up Nik Software’s Dfine 2.0 and I let the program loose on this shot. I used the automatic function, letting Dfine 2.0 do its magic. When it was finished, I applied it a second time, and look at the results in the below image. The picture is amazing. The noise is gone, the colors look great, and there is unexpected detail in the shadows that

were so dark one would assume there was no way to salvage those areas of the image. To reinforce my point, study the screen capture of the ‘after’ image taken at 100%, below. You see no noise. While the picture isn’t razor sharp like it would have been with a fast shutter speed and a low ISO, it’s quite acceptable, especially under the circumstances. The fact that it’s not tack sharp has nothing to do with using the Nik Software. That was caused because of the extremely slow shutter. Having said that, it is definitely sharp enough to be reproduced in a magazine.
What a great time it is to be a photographer!
