One of my favorite older images, this bird has graced my business cards. As I was chasing a couple of warblers in a tree one day, I heard a rustle behind me, turned around, and this bird had flown in to see what was going on, and hung around for a picture session.

Photography Before and After — Cinnamon Teal

Time for another in my Before and After series: I’m taking some of my best images and processing them through my workflow step by step so everyone can see what came out of the camera and how it is turned into the final image. (Look here to see all of the tutorials in the series)

The purpose is to explain my processes and techniques in the hopes that all of you will be able to borrow some of them for your own work, and because I hope to get feedback from you on techniques I haven’t discovered yet that will improve my own images.

I’d love to hear what you think of these articles and whether you find them possible. If you have questions on any aspect of them, please leave a comment or drop me an email.

Here’s today’s image as I originally published it. We’re not going to reproduce this, we’re going to start over with the raw and process it from scratch, so the final result will be different (and perhaps better). We’ll find out together…

In the last article I said I’d reprocess one of my bird photos this time. I’ve chosen a personal favorite that’s an older image that I think can benefit a lot by reprocessing with the knowledge I’ve discovered since I worked on this image. This image is from 2010 and was shot at Redwood Shores, a well-known location here in the Bay Area for winter ducks and shorebirds. I used a Canon 7D, my trusty 100-400 lens, and it was shot at 400mm at 1/800 at F8, ISO 400. Good light, fast shutter to freeze action, and moderate depth of field.

The first thing I notice on this shot is that it’s dark, and the duck’s head and tail are too dark. We can fix that..

Processing Cinnamon Teal

Here’s the image in its raw unprocessed form

Camera Calibration and Lens Correction

First thing you should do on every image is set your camera calibration and lens correction. Camera calibration is a subjective thing and different vendors and bodies will have different choices available. Adobe Standard will be there for every camera. With Canon bodies I find I prefer Camera Faithful almost all of the time. What this value does is give “hints” to the RAW rendering engine on how to interpret the data when rendering the image.

Lens correction profiles allow you to tell Lightroom what lens was used. If it’s a lens from a major vendor chances are a profile exists for it. This helps Lightroom auto-correct for certain lens flaws like chromatic aberration and distortions, especially around the edges of the frame. It’s possible to manually make changes as well, but for most images I don’t; the big exception being buildings where I need to straighten up walls and edges.

If your lens has a profile you should use it. If it doesn’t, leave this disabled.

Color Balance

Setting color balance is the next step, up in the Basic section. I’ve found that you can get decent color by using Auto White Balance but that I can rarely get the best possible color by leaving the choice to the camera. It gets close, but it rarely gets it perfect. Shooting in RAW mode allows me the option of deferring the white balance decision to when I process the image, though, so since I shoot almost 100% of the time in RAW, I almost always shoot 100% of the time with AWB set in camera. When I bring the image in to process, I’ll choose a specific white balance that I think best represents the lighting at the time.

This image was shot mid-day but the look of the water and the general light tells me it was overcast; the shadows are soft, the light is a bit greyish and diffuse. Looking at setting a base color balance I check between the Daylight, Shade and Cloudy settings. Shade is definitely too warm. Either Daylight or Cloudy would work, but Cloudy warms up the image while Daylight gives the duck what I feel are truer colors, so that’s what I choose. The color balance as set is pretty good this time, so I could have just left it.

Black and White Point

The next change is to set the black and white points. This will let you adjust the overall contrast of the image and help create the strong blacks and whites that can create impact in an image. Since the duck is dark and the overall image is dark, I’m going to start by raising the white point a fair amount (+56), but where I might leave the black point alone in a well-balanced image since it’s close to touching the left side of the histogram, in this case I’m going to pull back from the black side and raise the black point to lighten the image and set black to (+31). I may adjust that later, but this is a good starting point.

LightroomScreenSnapz002 600x280 Photography Before and After    Cinnamon Teal

The duck looks better already.

Exposure, Shadows & Highlights

Next up we adjust with the exposure, shadows and highlights sliders. Exposure sets the overall light levels for the image, while shadows and highlights adjust the light and darker areas independently. The shadows slider in Lightroom 5 has become a close friend of mine because it allows me to bring out the detail in the shadows amazingly well, and because of that I rarely turn to the tone curves any more (sssh: don’t tell photographers who live and die by adjusting curves, with Lightroom 5 I find it’s rarely necessary). 

If you look at the histogram, while the important details of the image (the duck) are quite dark, much of the image is very light. The exposure of this image was done by the camera and was probably on evaluative metering; the large amount of water convinces the camera the image overall is bright and it exposes for the water, leaving the darker duck under-exposed.

This image is a tricky one to expose well; there’s a lot of dynamic range here to squeeze into the image. One option would be to spot meter on the duck to get it properly exposed, but then the water is going to be much brighter and start blowing out highlights and you risk losing data in it. if I were shooting this image today I’d probably do that but use exposure compensation to pull the exposure back so the water wasn’t blown out. Another option would be to leave the exposure settings as is, but use exposure compensation to boost the exposure by half or 2/3 of a stop.

It’s a bit of a hobson’s choice, do you want to try to fix the duck’s exposure or the water? You’re really not going to get both right in camera, something’s going to need to be adjusted. My normal opinion is that I’d rather try to raise up the shadows than try to bring down highlights because you usually have more and better data to work with in preserving detail — but the side effect of that is a higher risk of noise coming out during processing. This is a common challenge with bird photography because you’re not working in a studio so you don’t control the light, you can’t do much to clean up massive dynamic range images in the field, and you can’t boss the model around to get them in a better position photographically. They tend to just duck-laugh at you and fly away. An option for some is to use fill flash using a hot shoe flash and something like a better beemer, but I’ve worked with that and it just adds more complication to getting the shot and personally, I don’t like the look of images taken that way as much. I’d rather work harder to find flattering light than trying to get all of the gear to cooperate, and flash just adds more gear to haul and curse at when it’s batteries run down at the wrong moment.

Because of the bright water, I won’t touch the exposure slider at all. Instead, I’m going to do the adjustment with the shadows slider. I’m trying hard to bring up the dark parts of the image without adjusting the water, since it’s very close to blowing out the right side of the histogram. Fortunately, we can do a lot with the shadows, and it makes a huge difference. Exposure stays at 0, Shadows go to +54, and to try to calm down the bright waters, I drop Highlights to -28.

One thing to note here. One reason I raised the black point in the previous step instead of leaving it alone is that it changes the starting point for the shadows slider by raising all of the dark tones. This effectively is pushing capabilities of the shadow slider even further towards lighter tones. if that doesn’t make sense, find an image with really dark colors in it like this one, and try raising out the shadows with the black point set so it’s almost touching the left part of the histogram, then try again after raising the black point. It’s almost as if you’re amplifying the effect of the shadows slider this way, and it gives you more oomph for bringing the dark parts of an image into balance with a bright overall image.

LightroomScreenSnapz003 600x280 Photography Before and After    Cinnamon Teal

Looking at the duck at 100%, you can see it’s really been lightened up and looks pretty good, but needs more work. The dark head is still too dark, but if I push it further using these sliders, the breast feathers start blowing out. I’m going to need to tweak this more selectively. And if you look closely, you’ll see that the processing has brought out that nemesis of photographers everywhere, noise….

Clarity and Vibrance

Clarity can be thought of as a “smart sharpener”, while Vibrance is an intelligent saturation adjustment. A bit of clarity helps most images; I typically set it around +20 and it does some localized contrast adjustments much like sharpening does; on good images, it can sometimes replace doing any sharpening in the detail module although I typically do both clarity and sharpening.

Vibrance has almost completely replaced the saturation slider in my workflow. the Saturation slider adjusts all instances of the colors the same, while vibrance will adjust lower-saturated colors more and high saturation colors much less, making it a more foolproof way to tweak the colors on the image. For this image I’ll use my normal +20 for clarity and vibrance.

 

LightroomScreenSnapz004 600x280 Photography Before and After    Cinnamon Teal

 

The clarity darkens the duck a bit, and the vibrance also intensifies the breast feathers a bit; and having seen that, I’ve decided to change my mind on exposure, and I’ve boosted it by half a stop, which lightens the duck’s headThe breast feathers may need a bit of a tweak later, but after seeing how the clarity and vibrance tweaked things, pushing the exposure a bit saves me even more detail fiddling later. On the other hand, the color noise is also enhanced (check the bird’s dark butt).

I still think the head is too dark. If I lighten it further now, I’ll mess up the body, so this is as far as I want to push it right now (but we’re not done yet). I hadn’t intended it as such, but this is turning out to be a great example of how sometimes the best way to fix thing is through as series of changes that all layer on top of each other, and how if you plan for that, you can take care of the big problems globally without messing anything up and then make more localized adjustments later. Learning that not everything has to be fixed with a big, global brush is a big step towards taking control of the Lightroom process.

Using HSL as part of that more localized fix is a huge part of that ability to work on limited parts of the image, so that’s next.

HSL — Hue, Saturation, and Luminance

Now we move to the HSL section where we can start adjusting colors with more precision. This section allows us to take specific color channels and change the color itself (hue), how saturated the color is, and how bright the color is (luminance). You can make some very dramatic improvements to an image this way, but if you’re not careful you can make the image look like it was snipped out of a bad sci-fi movie, so I’ve found a delicate touch is necessary.

One critical tool to learn how to use in the HSL area is the color picker. Each of the three color boxes have what looks  like a donut in the left corner; if you mouse over it it’ll show up and down arrows. Click on it to turn it on.

LightroomScreenSnapz006 600x280 Photography Before and After    Cinnamon Teal

You can tell one is enabled because it stays white and the arrows stay visible when you move the cursor away from it. You’ll need to learn to remember to turn it off, because it’ll stay enabled even when you try to go off and do something else, leading to wondering if your computer is haunted. It took me a few times to teach myself to always turn it off when I’m done.

LightroomScreenSnapz007 600x280 Photography Before and After    Cinnamon Teal

The way you use it is to find the spot you want to adjust, and click on it, then drag the cursor up to increase the values down to reduce them. It will adjust all of the colors that are part of the spot you clicked on; the side of the duck is both orange and red, for instance, and has more orange in it. I feel it’s a bit over-saturated, so I’ve clicked on the the side of the duck and dragged down, changing the red by -6 and the orange by -10. This is a LOT easier and more powerful than trying to guess colors and move the sliders individually. Once you get the hang of it, it’s a big help in doing area-based color adjustments quickly and easily. Since the only significant places in the image that have red and orange in it are the duck, it’s an easy way to clean up the colors of the bird. Note that the color changes are global, though — if red and orange existed elsewhere they’d be adjusted as well, which may or may not be what you want. There are ways to do even more localized adjustments which we’ll cover later.

Now I like the color and exposure of the duck’s body. The water looks good, too. I still think the duck’s head is too darl, but I can’t fix it here.  In some cases I might finish this in a plug-in like Viveza, but in general I limit the time and work needed to process through plug-ins for my best images, which this one, while nice, clearly isn’t. So we’re going to do the full job in Lightroom, which both makes it non-destructive and keeps it less complicated and usually, faster. It’ll be good enough for the kind of uses I’ll have for an image of this quality, since it won’t be one I’ll ever print or use in high resolution situations.

As much as I love how well Lightroom 5 processes images, I feel that almost any image can be improved further by careful application of some time and a plug-in or two — but I also feel that most images don’t warrant that extra work. I’d rather save that extended processing for the best images and not try to take something that’s pretty average and hope that some ‘magic’ will make it a better image than it is. Some images deserve a lot of careful and time-consuming processing. Most, in all honesty, don’t. One of the things I had to learn as I matured as a photographer was to know which images deserved that time and not waste time hoping a bit of lipstick will turn the pig into something prettier. That time is better spent going out and taking new, better images. Time is most often than not going to be your most limited resource. My belief is that a big part of maturing as a photographer is learning how to use that time efficiently and to maximize your effort on the images that will benefit from the extra effort.

Radial Fill

Now we’ll fix the duck’s head. To do that we’ll use a local adjustment using Lightroom 5′s radial fill. I’ve really come to like this feature, which is new to LR5. It’s the second tool from the right in the toolbar below the histogram, next to the adjustment brush. In Lightroom 4 and earlier, this adjustment would have been done with the adjustment brush, but the radial tool works for many of these operations and is even easier to use… So we select the radial fill and then drag out an oval covering the duck’s head, and then adjust the feather. I’ve found the best way to see how the masking and feathering will impact the image is to add a color to the filter while setting the location and feather of the fill, and then remove it when I do the adjustment.

LightroomScreenSnapz009 600x280 Photography Before and After    Cinnamon Teal

The radial fill gives you most of the power of the Lightroom processing engine, but it only affects the area defined by the mask. Even better, you can have multiple fills in a single image, the same way you can create multiple adjustments with the brush. This is a great tool for those small, localized adjustments and it has a surprising amount of power behind it. So first, I remove that color, and then I go about brightening the head.

You could do that two ways, by increasing the exposure, or by increasing the shadows. I went with the shadows because I wanted to minimize changing the eye, which is brighter. If I set the shadows to +30, the duck’s head now has the same tonal value as the body, but a Cinnamon Teal’s head should be darker, so I back that off to +15. I then decided the eye had been brightened a bit more than I like, so I added a second radial fill with no feather on the eye, and set the exposure to -.83. I also gave it a clarity boost at clarity: +45 to sharpen it. That’ll let me use more gentle sharpening in the next step.

I did consider doing noise reduction in this step, but I decided it would just complicate sharpening later, so I left it alone. here’s a look at the duck at 100% compared to the unprocessed version.

LightroomScreenSnapz010 600x280 Photography Before and After    Cinnamon Teal

 

Overall, I think that’s about as far as I need or want to take this image. Now some final cleanup and we’re done.

Final steps

The image is done, but we need to do some cleanup with final sharpening and noise reduction.

Disclosure: I’ve really struggle with sharpening. I’ve finally gotten decent at it, but it’s taken forever, and I still don’t think I’m anything remotely like “great”. For almost all of my web-based images I use some very basic Lightroom presets borrowed from Jared Platt that work quite well for me. When I start getting into my best images, I’m usually doing at least some processing in the Nik plug-ins and so I’ll use Sharpener Pro on them. I’ll definitely use Sharpener Pro when working on custom prints, although sometimes I’ll sharpen in Photoshop using a high pass filter. But for the typical online image I don’t worry about it excessively, especially given many online services (like Flickr) will ‘help’ your image with some magical sharpening and other tweaks when you upload to them. What really matters online isn’t to get the sharpening just right, but to not over-sharpen and not create visible artifacts, and it’s easy to get too aggressive and do that.

I’ll start with some moderate sharpening, which is Amount = 26, Radius = 1.0, and Detail = 50. Depending on the look, I might soften the detail to 25. Sometimes I’ll ramp up the sharpening beyond this but that’s fairly rare. For this image, my defaults look okay. The only real way to see the effect of sharpening is with the image at 100%.

LightroomScreenSnapz001 600x280 Photography Before and After    Cinnamon Teal

 

Now I apply a mask, which removes the sharpening from areas of low detail. The effect of this is to reduce the noise in those areas. I tend to apply masking more aggressively than many because I find I like the reduced noise — and in general, I rarely if ever add artificial grain to my images, preferring the noise-free look. Like sharpening, masking and noise reduction also need to be done at 100%. Hold down the option key and the image goes monochrome with light areas being affected by the sharpening and dark areas being excluded. I turn up masking until most of the low-texture areas have been excluded. In this case masking is set to 67.

QuickTime PlayerScreenSnapz004 600x257 Photography Before and After    Cinnamon Teal

Then I’ll do my noise reduction. There are two types of noise in an image, luminance, where nearby pixels are lighter or darker but of the same hue/color, and color noise, where random pixels have random colors in them. In this image, the luminance noise is minimal, but I’ve added a lot of color noise to the image.

Lightroom has separate controls for both types of noise. I’m going to start by reducing color noise, and then add a luminance reduction if I find I need it. As with sharpening, I’m using some presets from Jared Platt here. I add a small amount of color reduction (=25, detail and smoothness =50), and it makes a huge difference. I decide to add a bit of luminance and the difference is subtle but noticeable (=10, detail = 25). These screen grabs show the changes and the final values:

Final Thoughts

I don’t analyze images before reprocessing them for this series, I pick them because I think there are some interesting techniques I can show off with them and dig in. In this case, I hadn’t realized this image had some rather serious weaknesses because of the way I shot it and re-cropped it — things I doubt I’d do to an image today. This is all part of the maturation process, but in reality, I remember this image a lot more fondly than it’s overall quality returns. That said, it’s images like these that can sometimes be the best learning tools because turning them into something useful isn’t easy, and reprocessing this was an interesting challenge. I rather like the result, although I wouldn’t use this image other than on-line. I definitely wouldn’t try to print it.

The Cinnamon Teal is quite a pretty duck, also. I really need to go out and get some better images of them…

Thanks for reading, and for your feedback. Next time — I’m not sure. Any suggestions of an image of mine or techniques you’d like me to talk about?

I’ve also considered processing images by others; if you have an image you’d like to see processed by me, drop me a note and we’ll see if it can be done.

More Road Trip Snacks….

Welcome to yet another in what may be an infinite series of postings on the topic of Road Trip Snacks.

In Previous Episodes, I actually attempt to drink an Ensure (so you don’t have to), and then I introduce you to Clif Builders Bars as the best of a pretty inedible collection of “high protein” hunks of sawdust. Actually, the builder bars aren’t bad, just dry. Don’t try to eat one without a water bottle handy.

Here’s the challenge: I’m diabetic, so I’m trying to limit my carbs and sugars. I have allergies that prevent me from eating either tree nuts or peanuts, which nuke out a lot of the protein sources used in normal people’s snack foods. I’m not a big fan of indelicate digestive imbalances (ahem), so I don’t cheat on the allergies except by accident.

What I’m really looking for are edible (or drinkable) things that are low to moderate in carbohydrates, doesn’t require refrigeration and can be stuck in my car so it’s there when I need something out in the field when I really don’t want to head into civilization to grab food and can’t wait because my blood sugar is doing the lambada. Oh, and I’d like an ingredient list that looks like, well, food, and not like I’m chewing on a chemistry set.

This morning Laurie pointed me to an add for what seems to be a new entry into this growing class of products known as “breakfast shake”.

Google ChromeScreenSnapz001 150x150 More Road Trip Snacks....

 

Quaker Oats now has their own breakfast shake, with the special added super power of extra fiber. Because, you know, we all need to drink more fiber. Think about it and it makes sense: Quaker Oats does — oats. Oats deliver fiber, lots of it. So we’re going to liquefy oats and hide it in your breakfast shake. TADA: liquid oats.

But when I look at the ingredient list for this, I go “meh”. There’s nothing really wrong with it, but it looks just like the 20 other breakfast shakes I’ve looked at. It also has added sugar, a fair amount of it. at least it’s sugar and not high yield corn fructose.  I still believe all of the “strawberry” flavors across the product line were invented by some food scientist sadist, but typically, the chocolate is drinkable.

But still, meh. And so I said to Laurie “I don’t see anything in any of these products that should make me drink this instead of chocolate milk….”

And then I went “huh”.

Back when I was athletic and trained a lot on bikes and did the occasional road race, bike riders had this problem. It needed to go in the pocket of your jersey, it couldn’t require chilling, and it had to put up with some abuse along the way. Bananas were a given (and still are), as were Fig Newtons. When we got to the end of the ride, we’d hit up a store and grab a bottle of chocolate milk because it has that nice combination of sugars/carbs with a solid hunk of protein from the milk. And damn, after half a century it tasted wonderful.

Folks like Gatorade have spent a couple of generations trying to convince all of us that you need to eat or drink these specially formulated magic drinks if you want to be a serious athlete. Lots of people believe them — but if you look into modern training discussions, you’ll find a lot of people are figuring out that few of these drinks perform better for you than chocolate milk does, and many serious athletes have switched back. Ditto high-tech sawdust bars and things like, oh, Fig Newtons.

Sometimes the old ways are best. Although sometimes the old ways with a modern twist can make your day.

These days, you can get chocolate milk from a number of sources in no-chill aseptic containers. Some of them are organic. Most of them have that added sugar, of course, so that their nutrition label looks a lot like the breakfast shakes. Still, if you want something you can haul around without worrying about it going bad that tastes decent and has a rational nutritional basis, you can do a lot worse than these “kiddie” boxes and bottles of chocolate milk.

And you can even go one better. if you look, you can find this:

Google ChromeScreenSnapz002 More Road Trip Snacks.... 

Nestle, bless them, has a no-sugar-added version. it uses a bit of sucralose to sweeting, but the carb load drops significantly: the sweetened version of this is 150 calories with 25 grams of carb and 8 grams of protein. The no-sugar added version is 100 calories with that 8 grams of protein, but only 13 grams of carbs.

I now have a supply of this ordered, and when it gets in, I’ll do a taste test and report back. But this looks like a nice thing to have handy in the car, and it’s — chocolate milk. How bad can it taste? the ingredient list is surprisingly short of things that scare me, although it does have Cellulose Gel (good that gives it a good mouth feel), Potassium Citrate (manages PH and adds some tartness), Carrageenan (another goo that gives it a good mouth feel, made from kelp) and Cellulose Gum (it’s Cellulose Gel, but different). The sodium hit is a bit high but not terrible.

By the way, when I’m out on the road, one of the things I’ve started doing is hitting up a coffee shop for a mocha — hot or cold, depending on weather, think about what a mocha is: it’s effectively chocolate milk with a coffee chaser. And given how easy it is to find a Starbucks most places, it’s an easy way to get a drink with a balanced nutrional load (but hold the whipping cream; we can argue full-fat, low-fat or skim milk some other time. I’ve been moving away from skim milk to 2% personally because the fat slows how fast the carbs get digested, and I really don’t want a higher % of carbs in my diet — low fat is not a good thing for me. And perhaps most of us. But… later).


By the way, you might be amused at my Valentines Day gift from Laurie, a Coleman iceless cooler More Road Trip Snacks..... So now I have a lot more flexibility to carry reasonable food with me, and less dependence on hotel refrigerators that actually work or can refreeze blue ice blocks. I am looking forward to trying it out on my next trip (Yellowstone, baby!) when I can set up my lunches and haul them with and be less dependent on trying to wade through fast food or poor deli counters… oh, and cold drinks that are really cold…

(as laurie notes, you have to be careful with these coolers; many only guaranteed 10-15 degrees below ambient, which can be a problem. This seems to be the best of the bunch in the consumer price ranges…)

And onward… There are options, it seems…  It can just be a challenge to figure them out…
