Welcome to part one of my series of reviews of HDR software. If you want to read more about why (and how) I’ll be doing these, you can read My Introductory Post.
I’ll start my reviews by taking a look at the product closest to the top of the alphabet, the Enfuse Lightroom Plugin. The plugin is based on the open source Enfuse application, which was tweaked to fit into a Lightroom Plugin format. Technically, the Enfuse application isn’t a true HDR application (because it doesn’t generate a tonemapped image) but it does offer the ability to blend multiple exposures in order to get a wider dynamic range. I decided to add this to my list because I have heard that many people like Enfuse because it yields a very natural looking final product. If you want to “amp” things up a bit you can always do further editing in something like Topaz Adjust or any number of other applications.
Before I dig into the review I want to let you know that I decided to change things up a bit regarding the sample images I’ll use to run through the various applications. Instead of my driveway shot, I’m adding a set of shots from my parking lot at work that I took with my little Canon S95. The S95 produces RAW files of around 10mb each, so they are smaller than the files from my T3i. I’m also adding a series of 7 images from RC Conception, a popular photographer/Photoshop expert that you can follow on Google +. He uploaded some RAW files (I’m using seven of the nine) from a nighttime shot of San Francisco(you can view/download them here) and asked people to process them on their own to see what they could get. I think it will be a good test of the various applications, especially in seeing how long it takes to render the image. Also, RC uses a Nikon so this way I can’t be accused of bias towards Canon :-) So, here are the two image sets I’ll be using (I’ll just show the San Francisco image after merging):
Set 1-The Fire Truck
Set 2-The Parking Lot
Ok, back to the LR/Enfuse Plugin review:
Once you have downloaded and installed the plugin into Lightroom, you use it just like you would any plugin. Select the images you want to “Enfuse”, then go under File-Plugin Extras-Blend Exposures Using LR/Enfuse:
After you click that selection you will be presented with a window that has four tabs on it. The first tab is “Configuration”:
This tab is where you select the configuration of Enfuse’s processing and preview options. I pretty much have left them in their default state. Next,you click on tab two, the “Auto Align” tab:
This tab is pretty self-explanatory. The plugin has an auto-align feature. I don’t think I’ll be using the feature much as I plan on shooting as many bracketed shots as possible on a tripod. For the reviews though I will test the speed of the application with the “auto-align” box checked and un-checked. Onto the third tab. Tab 3 is the “Enfuse” tab, click it:
This is where you assign the relative importance of three components, Exposure, Saturation and Contrast. As the text in this tab says, Exposure should get the most weight for exposure blending while Contrast should get the highest weight for focus blending. I left everything here on their default settings. Click the 4th tab, which is where you will tell Enfuse where/how to output you files:
As you can see, I chose to add the enfused image (as a TIFF) to the same folder as the originals but with “_Enfuse” appended to the file name. I also reimport the image into lightroom with all of the metadata.
After you have gone through the tabs once, they stay the same for future uses, or you can change options if you want.
Now, all you need to do is click the “Enfuse Images” button (on the lower right), and wait… Here’s how long it took:
- fire truck set w/align images checked- 3 minutes
- fire truck set w/align images unchecked- 52 seconds (MUCH,MUCH faster, which proves you should use a tripod whenever possible!)
- parking lot w/align checked- 2 minutes, 10 seconds
- parking lot w/align images unchecked-26 seconds (once again much faster)
- San Francisco (7 images) w/align checked- A LONG Time (over 4 minutes)
- San Francisco (7 images) w/align unchecked- 53 seconds
Let’s see how the “Enfused” images turned out. In all cases I’ll be comparing the “properly exposed” image (shown 1st-the one without any exposure compensation) to the initial output image from the software.
Analysis:The image produced by the LR/Enfuse plugin has picked up more detail just about everywhere. The roof of the shed shows more detail, the grill of the truck reveals more of the engine and the bottom of the truck shows more detail in the front suspension. Color reproduction compared to the original seems very good and nothing seems washed out.
Analysis: The biggest difference I see is that the sky has more detail. The clouds are more distinct and the sky has quite a bit more blue to it. The shadows are still there but you can see deeper into them. The “sunstar” on the black truck still sparkles although the color of the flowers seems a little less saturated. Overall though, it is a nice improvement.
Analysis: Enfuse did a good job with the city at night. The detail on the roofs of the buildings is much more visible. The sky lightened up a bit, revealing some of the sky-glow that was missing. All in all, the city looks more alive in the Enfused image and I think a better representation of what you would really see if you were standing on this rooftop.
As I said in the beginning of this, the LR/Enfuse Plugin isn’t true HDR software. Rather, it blends multiple exposures together, taking the “best pixels” from each exposure (based on the weightings you assign to exposure, saturation and contrast). There is no HDR tone-mapped image created but the end result is often just as, sometimes more, pleasing than an HDR application produces, especially if you are looking for a more natural result.
Based on the test images I used here as well as some other bracketed photos I’ve played around with, I am very happy with LR/Enfuse. It does what it’s supposed to do very well, without a lot of fuss or excess complication. True there aren’t many options for additional editing in the plugin. For that you’ll have to use an outside Post-Processing software like Photoshop, Topaz Adjust (which I use) or any of a number of others. Here’s a quick image I made in Topaz Adjust from the Enfused image:
All I did was increase the detail and saturation a bit using one of the many presets that Topaz Adjust has. It’s nothing spectacular but it is definitely different than the Enfused image.
In short, the LR/Enfuse plugin positives are:
- Is a great way to blend multiple image quickly and easily without having to fiddle around with a bunch of presets.
- Provides a well-balanced, natural looking output.
- Blends fairly seamlessly into the Lightroom workflow.
- Is very affordable. Since It’s “donationware” you can purchase the full, unlocked version for a reasonable price.
- It isn’t a true HDR/tone-mapping application.
- You will need to do additional post-processing in another application if you want to tweak the Enfused image to anything beyond a natural looking result.
- The speed of the plugin is reduced considerably when the “align images” box is checked so use your tripod!
- There is no ability to reduce any ghosting (people moving, etc.)
The LR/Enfuse Plugin is a keeper!
