In this workshop Tim Grey teaches how to use Nik Software's HDR Efex Pro 2.0 to create great high-dynamic-range (HDR) images. After showing you the basics of HDR Efex Pro—including configuring the interface and settings, using presets, and evaluating your image—Tim introduces the various adjustment options. Learn how to make overall tonal and color adjustments, use control points to apply selective adjustments, and reset adjustments or go back in the history. Plus, get tips on applying finishing touches to your images and saving the final processed image.
And as you're working on adjusting the settings for your HDR image, from time to time, you might want to take a step backward. In other words, you might want to undo a step, or go back to a previous interpretation of the photo. Obviously as you're working on the image and evaluating the results, you might want to take advantage of the compare view or even the split view in order to get a better sense of the overall effect within the image. Now certainly, you can simply refine the adjustments. You could choose a different preset, you can adjust the settings over on the right panel, but sometimes, you may want to go back to a particular history state.
Let's take a look at the History section found on the left panel. I'll simply click the header for History and you can see a history of everything I've done to the current image. You can see for example, that I went through a series of different presets trying to decide which option might work best for this particular photo. And then I took a look at some of the tone mapping adjustments over on the right panel. That included some adjustments to structure, saturation, temperature, tint, etc. And if I decide that the current interpretation of the photo is a little less than ideal, I can always go back in time, as it were.
I can go back to a previous history state and then continue on from there. Let's say, for example, that some of the adjustments I applied, I'm just not happy with. Maybe I want to go back to the last preset that I assigned. In this case, Dramatic. Or perhaps I just want to go back to before I applied a temperature adjustment, in this case, a saturation adjustment was the step I performed right before temperature. As I click on each of these individual items in the History list, you'll see that the image is updated to reflect that particular state, the way the image appeared at that particular moment in time.
Once I've decided that I would like to go back to a particular moment in history, then I can also start moving forward with additional adjustments. You'll notice that right now my dramatic preset is the last history state that is actually affecting the image. I can also see dimmed out the additional adjustments that I applied after the fact. Now that I've taken a step back in History, if I start applying adjustments to the image, you'll notice that those additional History items that had been dimmed out are no longer available. So once I go back in time, as it were, to a previous History state, and then start applying additional adjustments, the steps that I had undone by going back in time.
Will no longer be available. So obviously the history can be very, very helpful in HDR Effects Pro. But it's important to keep in mind that it is a linear history. We can go back in time to a previous state for our image, but then once we start applying additional adjustments, we're no longer able to get back to the adjustments that we had undone. In other words, you can go back in time but you can't pick and choose which individual steps you want to undo. But again, keep in mind that all of this really just relates to the settings that are found over on the right panel.
So in addition to going back in history, we can also simply refine the settings over on the right panel. Of course, the benefit with history is, we know exactly what we're going to end up with. We might not be able to anticipate exactly what we need to do to the adjustments on the right panel to get back to a particular history state. Whereas looking at the list of available options, of available History states, in the History section of the left panel makes it very easy to go back to a particular condition for the photo while we're working on it.
