Lake Eaton at Night-from the camera
A quick look at editing
Let’s take a quick look at editing. I say quick because I haven’t figured out a way to squeeze this into a reasonable length post if I go into great detail and add screen captures to show the steps in Photoshop. If there is any interest in that I’ll give it a try.
Look at the image above, it was taken at Lake Eaton in the Ocala National Forest this last Friday. I took my son there on a scout camp-out. The light on the horizon is the urban area to the west. You can see some stars in the sky but it is basically black. As is the foreground. The whole image is dull and low contrast.
After ten minutes in CS4 we get this below:

After some work in CS4
This is still no great image and it does look a lot better in larger sizes. But now we can see that there are a lot of stars. The sky is midnight blue. The lake water now pops out in a reflection of the orange sky and clouds. There was a large forest fire to the east of this area and that was imparting the smoky orange tones. There is now a boat visible in the right foreground. Let me note that this shot was a 3 minute exposure but the histogram was mostly to the left since I actually shot 6 of these images and intend to stack them. But that is for another post.
How did I get from the first image to the second image?
Edits
In ACR5
- Increased fill light to +67
- Added contrast and just a little more exposure
- Added clarity and vibrance
- Decreased the color temperature to 3050
- Use 5 adjustment brushes
- Reduced noise
In CS4
- added a layer copy
- used noise ninja on the whole layer
Starting with the ACR (Adobe Camera Raw 5) work. The histogram was pushed to the left (Histogram 1 below), so I pushed the fill light slider far to the right from almost zero to +67. That moved the histogram a little to the right (Histogram 2) and brightened the stars and foreground. This revealed the boat.

Histogram 1

Histogram 2
The only reason I can do this is that this shot was captured as a raw file. That gives you 1.5 to 2 stops of leeway at both ends of the histogram. You can recover both shadow detail, as I did above or recover blown highlights on the right side of the histogram. In a jpeg file this is not possible.
I then add just a little more exposure and some contrast which makes the stars pop out a bit more. I reduced the color temp from 3150 to 3050 to make the sky more blue but this makes everything else bluer too.
Why dod I pick the various adjustments? It is just from my experience working in ACR. I make adjustment until I like the effect. You can always go back on these adjustments if you think you went too far.
All of this can be done in CS3 and ACR4. But in CS4, Adobe added adjustment brushes to ACR5 and you can use these brushes to add local changes in exposure, contrast, clarity and several other adjustments to the image by brushing them in. I used this feature five times to brush in more contrast and less exposure to the sky. More orange and adjusted the exposure on the lake with another brush. And used a third brush to do similar adjustments to the skyline and clouds just over the trees. A last couple of adjustment brushes dimmed the foreground weeds and lightened the boat.
All of this added a lot of noise so I used the noise reduction feature in ACR to reduce this. And then moved to CS4.
All I did in CS4 was do a single run with Noise Ninja to reduce the noise further. And I added a copyright watermark.
Why work in ACR?
Everything I did in ACR could be done a different way in CS4 or CS3 (and probably earlier versions of Photoshop). The adjustment brushes could be duplicated by selecting the area and creating a mask. You could then use dodge/burn, curves and saturation to recreate the effects. But by working in ACR you are working in the raw linear data and changes are easily reversible and do not introduce as much image damage.
You could also duplicate this in other editing software. The ability to use layers and masks would make that easier.
So I wanted to give people a brief look at what I do in editing. I probably could have picked a better sample image to work on. I have no hesitation to do any sort of editing that I think improves the image.I never claim that my work is a representation of the scene as it naturally appeared. The sky was black, the only star really visible was Venus and the boat was dimly visible to my eyes. But it is a representation of my ‘artistic’ vision of what I want to create.

Bryan,
Most useful, for me, it would be even more useful if you could find the time and the will to do the full thing.
Personally: I don’t find the length intimidating at all, I’m currently reading Edward Gibbons, “The History of the Decline and Fall of the Roman Empire”, so length is not an issue:)
FWIW, the text is very readable on your page and I like it. The explanations nice and easy to understand.
Thank you.

I do not use CS3 or 4 but have become a Lightroom fanatic.
This program helps me process the number of images I have to deal with on a daily basis.
The adjustments you made to your photo are very recognizable to any Lightroom user. I use all these features and many others regularly.
The ability to recover a marginally usable photo from a raw file is an understatement.
Thanks,
Mark

I understand that the LR Develope module is essentially ACR now that Adobe has added adjustment brushes and such to ACR5

OK let me think about the best way to do it.
