Adobe Photoshop Lightroom 2: Development workflow

I recently had the opportunity to put this fine photo editing application through its paces--one of my cousins got married a couple of days ago, and I shot about 350 RAW images across the different marriage ceremonies (you'll find some on my Flickr Photostream). Faced with the prospect of churning out high-quality images from these RAW images in record time, I happily dug into the famed Lightroom 2 workflow. After several bouts of trial and error with color configurations and tweaking sequences, I arrived at the following workflow which I believe enabled me to extract the maximum quality from my RAW images in the shortest possible time. Remember that I already used Presets and Default settings to bring my photos to a more natural, higher-quality level before performing editing individual photos using the following steps.

1. Crop the photo: The crop tool can spell the difference between a good photo and a great one. While in the Develop module, hit [R] on the keyboard or click the Crop overlay icon indicated in the adjoining screenshot. Use the mouse to draw a box that defines the crop you need, or simply drag the control points of the crop box and pan the image until you're satisfied with the most interesting frame. Hit [Enter] to apply the crop.
2. Adjust White Balance if necessary: From the Basic settings in the Develop panel, click the dropper icon (indicated), and click on a gray or white portion of your photo. This will fix any color cast that might exist. Alternatively, you can intentionally invoke a color cast by playing around with the Temperature slider (labeled Temp) to impart a warmer or cooler color tone to your photo.
3. Adjust Exposure: Now begins the meat of your editing. For the majority of your images, you can move the exposure slider until the Histogram graph spreads evenly, without clipping in the highlight (right) area. 4. Adjust Blacks: Adjust the Black level until the left side of the graph tapers off without bunching up against the left edge. 5. Adjust Fill Light: Fill light refers to the light in the shadows of your image. Increasing this slider value will bring out some detail in these darker areas of your photo. 6. Adjust Recovery: This refers to highlight recovery, and is used to recover detail from highlight areas that might be blown out. Be careful with this setting--increasing it too much might make your image appear unnaturally flat. 7. Adjust Brightness/Contrast: Play the Brightness slider against the Exposure slider to get the colors and balance your image just right. Remember that the lower the brightness, the better will colors show through.

These steps will get you off to a good start with bringing your images to a high-quality level. Next up, I'll focus on some Lightroom 2 tricks that will help enhance specific photos, like those of people, landscapes or food.

Adobe Photoshop Lightroom 2: Initial configuration

Ok, it's official: I'm hooked onto Lightroom 2. The sheer power of this program, its slick interface, and brilliant attention to user interface makes this the best imaging application I've ever used for my photographs. If you haven't read my initial experience with Lightroom 2, you'll find it here.

The groundwork 
Lightroom 2 offers several methods to help you streamline your photo processing workflow. The following steps will help you set up your Lightroom 2 environment with pre-defined settings that will lift the quality of your photographs during the import process, even before you begin tweaking them! This will let you reach your final result faster. You only need to perform the following actions once--they will subsequently invoke automatically each time you import your photos:

1. Define a camera profile: When I first started using Lightroom, I noticed something strange while importing photos--when each photo first flashed on the screen during the import process, it appeared to have nice, vibrant colors. But after getting imported into Lightroom, they appeared rather dull and faded. I needed to do a fair amount of tweaking with the saturation, highlight and black level settings before I was satisfied with the result. I later discovered that I wasn't using my camera's profile. Lightroom lets you define a profile that is specific to your camera model. Using this profile delivers a significant improvement in color rending, resulting in more vibrant and balanced images, so you'll need to do lesser work to bring your photos to the final satisfactory level.

First, head over here to download the camera profiles installation file from the 'Downloads and Installation' section (free registration required), then install this file. You will now be able to see the camera profile in the Camera Calibration section from the Develop module of Lightroom 2. Click the Profile drop-down at the start of this section, and select Camera Standard beta 2 (I found this delivers the most natural colors).

2. Assign default settings to your specific camera and ISO: In Lightroom 2, click Edit, Preferences..., and select the Presets tab. Ensure the 'Make defaults specific to camera serial number', and 'Make defaults specific to camera ISO setting' are selected. The significance of these settings will become apparent in the following step.

3. Define sharpening presets: Lightroom 2 features powerful sharpening and noise reduction tools to help you bring out image detail and clean up photos shot at higher ISO settings. The cool thing about Lightroom 2 is that you can create setting presets and bind them to specific ISO settings for your particular camera. This means you could define noise reduction presets for each ISO setting (where you would generally apply more noise reduction for photos shot at higher ISOs), and you can automatically invoke these presets while importing new images: the appropriate sharpening levels are automatically applied to photos according to their ISO. Cool, huh? This capability saves you the time you'd otherwise require for applying noise and sharpening tweaks to your newly imported photos. Here's how you create these presets:

Start by opening a photo shot at ISO 400, for example. Apply the sharpening and noise reduction settings until you are satisfied with the reduction in noise in your photo. The adjacent screenshot shows the settings I use to reduce noise at ISO 400 for my D40. View the photo at 1:1 zoom to be able to see the effects of the noise reduction.

To to save this sharpening preset, click the 'plus' symbol from the Presets section on the left panel. In the box that pops up, make sure to check only the relevant sections that you have modified. Note that besides the Sharpening and Noise Reduction settings, I've also selected the Calibration option so that the camera profile will also be saved in this Preset. Finally, to set this preset as a default camera setting, press the [ALT] key, and click the Set Default... button at the bottom of the Develop panel. A box pops up verifying your camera model number, serial number and ISO setting. Click the Update to Current Settings button. Now repeat this step for photos shot at different ISOs, each time saving your Sharpening, Noise Reduction and Calibration settings to a new Preset for each ISO setting, and updating the default settings.

That's it for the initial Lightroom 2 configuration. From now on, each photo you import will be automatically processed with the selected parameters according to your specific camera, and the photo's ISO setting. When working with tens and hundreds of photos, you will save significant amounts of time with these settings. Note that these are only presets: you are free to modify these settings while working on individual photos later on.

In my next post, I'll be talking about the basic settings and workflow I use while processing individual photos. Stay tuned!

Become a human calculator

The one thing I detested about mathematics in school was the way the education system made it so theoretic. Learning trigonometry or Calculus was anything but fun, and it certainly didn't appear to be practical at the time. Even today, how many times do you hear kids say, "What am I ever gonna use this stuff for?" Math is, in fact, the most practical science there is--from calculating the curve of an aircraft wing (Fourier math playing a big role here), to modeling financial forecasts (mathematic extrapolation), math is the very foundation for almost every device and technology we use. But for the majority of us, it really isn't a cause excitement. So wouldn't it be great if there was a way it could actually help our everyday lives: like giving us the power to be the fastest human calculator at dinner with friends? That'd certainly beget admiration points! Well, there is such a field of mathematics that can help you do just that--it's called Trachtenberg Mathematics.

Trachtenberg Mathematics was invented by a brilliant Russian mathematician named Jakow Trachtenberg while he was imprisoned in a Nazi camp during World War II. He devised a simple set of rules that can help perform relatively large calculations quite easily. Sounds too good to be true? Check out this excellent Web site that explains this technique with lucid examples. After you're acquainted with the basics, there's a handy little software you can download here, which will help you get practice on this technique of speed math.

On a related note, you could also check out a similar form of speed math called Vedic math. There a ton of information behind this Wiki link. Also, here's still another really fun way to multiply numbers by simply drawing lines on paper! See the video below:

Finally, check out this excellent online resource devoted to speed math here. Hint: The tricks taught by these techniques are a great way to put an interesting new spin on teaching the subject to kids! Math? Fun? Who could have ever imagined?

Hard disk defragmentation: The easy, free way

If you're already well-versed with the concept of disk fragmentation, go ahead and skip to the next paragraph. If not, let's walk through why defragmentation is important to you. Computers are a lot like pets--you have to take care of them if you want them to stay healthy. I know, it's not the best of metaphors, but it's close. Computers consist of several components, all of which play an important role in its overall functioning, and eventually in providing a satisfying user experience. The component we'll examine in this article is the hard disk--the storehouse that holds all your applications and data. To visualize how it works, think of a hard disk as a cross between a magnetic tape and a record player. Of course, they have smaller electronics, faster speeds, and higher capacities. Hard disks consist of one or more magnetically coated platters on which the data is stored. This data is read by tiny heads that 'fly' above the magnetic surface as the hard disks spins. The heads are mounted on arms that are similar to the pickup on a record player. But like I mentioned before, the speeds are much higher--the platters are designed to spin at up to 10,000 rpm and the head/arm assemblies can move from the inner to outer track and back 50 times per second. Yes, they're that fast. So what has all of this got to do with defragmentation? Well, whenever you load an application or save data on the hard disk, it is written in the form of discrete 'blocks'. Depending on the size, a file can consist of one block or thousands. To maximize the storage space, these blocks need not be written in a sequential order--they can be scattered across the hard disk depending on the other data that is stored. The computer's operating system keeps track of these data blocks in a table--much like an address book. When a file is created, deleted or moved, it's address is

updated. Now the problem starts over time, when files, programs and applications are removed, loaded, copied and erased: the blocks of data that comprise a single program might be spread across the entire hard disk. Subsequently, the hard disk read/write head needs to work that much more to read or write a file as it locates its chain of blocks. But there's an easy remedy: arrange all of the blocks that make up the programs and files in contiguous sections so the hard disk can access them sequentially. This results in quicker access times and data transfer speeds, faster bootup, quicker application loading, and a smoother user experience. Defragmenting your hard disk can also maximize its operational life as it needs to do lesser work to access its data. Let's take a look at one of my favorite programs to get this job done.

Disktrix UltimateDefrag Freeware Edition
This program is the Swiss Army Knife of defragmentation tools. There is a lot to like about it including the several defragmentation options, the comprehensive user manual that nicely explains the theory of defragmentation, and that fact that there's a free version available for this software. But the aspect that trumps other defragmentation programs is its ability to relocate applications, files, programs and directories to locations on the hard disk where access is fastest. And you can specifically select these applications. So if you're a gamer, you can optimize your installation of Bioshock, or if you're a digital artist, you can tune Photoshop for quick startup. Grab the free version here or the commercial version here. Be sure to read the manual if you want to deep-dive into what the program does. Unlike most other defragmentation tools, this one delivers results--I have a happier hard disk to prove it.

Adobe Photoshop Lightroom 2: I'm getting hooked...

In a recent post where I wrote about how I process RAW images from my Nikon D40 using Adobe Camera RAW, a reader replied asking about RAW processing tools with a little more chutzpah. I've been following the buzz that's surrounded the recently-launched Adobe Photoshop Lightroom 2, and decided to dive in and try it out.

I'm the kind of software user who builds long-term relationships with my applications. I need to coax myself a fair bit before committing to anything 'new and improved'. When I do encounter something that promises to change the way I live, I go through several phases that include flirting with the new software, reading about its capabilities and other users' experiences with it. It takes a while before I convince myself to toe-in and test the waters.

When it comes to processing images from my camera, I've always known, loved and trusted Adobe Camera RAW. Sure, it's no Swiss Army Knife of image processing, but it's simple, efficient and entirely effective. I've been using it for years and have never really felt the need to use any other solution. But recently, the lure of an enticing new interface,  a workflow-optimized layout, cool new tools for touching up portraits, and advanced photo cataloging capabilities was too much. A couple of days ago, I downloaded the trial version of Adobe Lightroom 2 from its Web site here (free sign-up required), and have been deep diving into its capabilities ever since.

Some of the key 'a-ha' points with this application include:

• Local adjustment brush: You can now 'paint in' exposure, brightness, contrast, even clarity and sharpness. These effects work like a layer mask, so you can also vary the intensity of these effects. And all of these changes are non-destructive.
• Enhanced organizational tools: The process of importing files from disk or memory cards is quicker and more intuitive even compared to Bridge in Adobe Photoshop.
• Volume management: You can browse and edit directories, drives and files as you would using a standard file management tool, and easily create quick groups of images.
• Extensible architecture: Like Photoshop, Lightroom 2 can accept plug-ins written by third-party developers, helping extend its functionality and capability.

Other enhancements to the application include DSLR profiling, multiple monitor support, flexible print options, streamlined Photoshop CS3 integration, enhanced output sharpening and 64-bit support for Windows and Mac OS.

There are hundreds of in-depth reviews about this application out there, so I'm not going to repeat the superlatives that you'll already find in these write-ups. But here are some of the smaller aspects of this software that I personally found fantastic:

Compare views: Lightroom 2 offers several views to help you see the before and after effects of your modifications, including split screen, side-by-side and above-below. Intuitive. Simple. Hint: Click these images for a larger view.
Excellent Sharpening and noise reduction: If you shoot at  higher ISOs, you'll love the new Sharpen and Noise Reduction capabilities. I was amazed as the creamy smoothness of a corrected image, and its ability to retain sharpness. I'd recommend Lightroom 2 for these two features alone.
Quick development options in the Library view: Instead of having to trundle through the detailed image settings in the Develop module, there's a Quick Develop panel that lets you adjust basic image settings in the Library module. This functionality lets you quickly make broad image modifications before drilling down later.
Lights Out: This is one of those features you'll like playing with. Hitting the 'L' key will gradually dim the interface leaving only the image in clear view--great for those times when you want to eliminate the noisy background and concentrate on your photograph.
Keyboard shortcuts galore: Its easy to whiz through the interface and get plenty of image processing done quickly, after getting accustomed to the keyboard shortcuts. You can be the Liberace of Lightroom. Sorry, couldn't resist that.

 

Lightroom 2 has certainly made RAW image processing a whole lot more fun. And it's fast. To know more, head over to the Adobe Design Center where you'll find Help files and video tutorials. You'll also find a host of informative video tutorials and end-user experiences on YouTube and MetaCafe.

Now I've only got to find a way to cough up the $299 after the 30-day trial period ends. But I'll cross that bridge when I reach it. Get it? Bridge? Adobe? Oh, never mind.
