Today, professional photographer Laurence Norah of Finding the Universe, finishes his five-part series on taking better travel photos. In part five, Laurence is giving some simple post-processing techniques that you can use to make your travel photos wow your friends and family! Editing your photos is just as important as how you compose them, so I hope you’re ready to take some notes!

One of the most misunderstood parts of digital photography is what happens after you take the shot: editing your photos, aka post-processing. This is where you edit the images you have taken, to create the final product.

Post-processing is the equivalent of the darkroom from the days we shot in film.

In today’s post, we’re going to be covering some ideas for editing your photos, from the basics (cropping and leveling), through to more complicated actions like recovering shadow and highlight information.

Editing Photos: 7 Editing Tips for Your Travel Photos

1. How to Crop Your photos
The crop tool allows you to change the size of your image, and also to change the aspect ratio. For example, you can crop an image from a rectangular shape to a square shape. There are many reasons you would want to crop, including for publishing in different formats and aspect ratios.

Let’s take a look at the first photo from this post, a lightning shot I took on a recent trip to the Florida Keys. Here’s the original version without cropping:

And the edited version, post-crop:

Compared to the original, I have cropped the image to remove the dark part of the pier on the right-hand side of the image and recomposed using the rule of thirds, so I have one-third land and two-thirds sky. This makes the lightning bolt more the focus of the shot.

You might wonder why I didn’t just compose properly when taking the shot. Well, in this case, I was doing a long-exposure shot without a tripod, so had the camera balanced on the edge of the pier for stability. That very much limited my ability to perfectly frame the moment, so I just shot wider, knowing I’d be able to crop the shot appropriately after the fact.

Let’s look at what cropping looks inside a couple of the tools available.

Here’s an example of cropping in Snapseed:

And the same thing in Lightroom:

In both cases, cropping is very simple: it just involves you selecting the crop tool and then selecting the area you want to keep with your mouse or finger. Then you apply the changes, and voilà, your new cropped image is ready to go.

As you see from this and later examples, the tools look similar across different platforms, so it’s easy to apply the learning you have from one tool to another.

2. How to Level Your Travel Photos
One of my personal petty annoyances in photography is when the horizon line in a photo isn’t level. Sometimes when we’re caught up in the moment, this basic compositional rule is forgotten — but the good news is that editing your photos to make them level is also very easy.

I’ll use the lightning shot as my example again. Balancing the camera on the edge of the pier meant that the shot wasn’t level — this is particularly noticeable to the eye when the image has a clearly defined horizon line, such as the sea.

If we look at a zoomed in version of the image in its original form, with a line overlaid near the horizon, we can see that it’s not level — the line is closer to the horizon on the right-hand side than the left.

In Lightroom, the level tool is part of the crop tool, and you can just rotate the image to suit. When you use the level tool, a grid will appear to help you get the alignment correct. Here’s a screenshot of that in action in Lightroom.

And here’s the same procedure in Snapseed, where the level tool is called “Rotate”:

Leveling an image is a really simple task that will take just a few seconds of your time, resulting in a much more visually pleasing image.

3. Vignetting Your Photos
Vignetting is about making parts of the image darker or lighter than other parts, in order to make it clearer what the subject of the shot is.

Some tools restrict your vignette to the corners, but in applications like Snapseed and Lightroom you can selectively darken and lighten areas of the image — you don’t need to restrict yourself to the corners.

Taking the lightning shot above, let’s load up the vignette tool in Snapseed.

Here we have options for how big to make the “center size,” i.e., the area to be edited. Inside this area, everything can be made brighter (inner brightness) and everything outside the area can be made darker (outer brightness). We can also do it in reverse, making the inner darker and the outer brighter.

Let’s apply the vignette tool to the lightning bolt, to give you an idea of the effect:

Above are the settings I chose for outer brightness and inner brightness, while below is the size of the vignette itself, which is based on the center size setting.

Vignetting is particularly good for portraits, and anywhere where you really want to make the subject of the image more clearly obvious to the viewer.

4. How to Change Shadows and Highlights in Your Photos
Sometimes when we take a photograph, parts of the shot might end up being darker or brighter than we want. We refer to the dark areas of the shot as shadows, and the bright areas of the shot as highlights.

We can fix this by changing the brightness of the shadow and highlight areas specifically, using either the “Shadow” or “Highlight” tool. This is a tool that works particularly well on RAW files as they retain more information on the shadow and highlight areas of an image compared to a compressed JPG, which discards most of this information in order to save file size.

Let’s take a quick look at adjusting shadows and highlights using Lightroom. In Snapseed, shadow and highlight adjustment can be found under the “Tune Image” setting.

Here’s a shot of a couple enjoying a bonfire and fireworks display in Edinburgh during Hogmanay:

As you can see, the fireworks and bonfire are clearly visible, as are the torches the couple is holding, but the rest of the shot is dark. Let’s adjust the settings and see what we can get.

Contrast tutorial with fireworks at hogmanay in Lightroom - afterContrast tutorial with fireworks at hogmanay in Lightroom - after

In this version of the image, the couple is much more visible, as is the hill the fireworks are on and the surrounding crowd.

To achieve this I increased the overall exposure of the image, making the whole image brighter, including the shadows and the highlights.

Then, as the shadow areas were still a little dark, I increased those a little more.

Finally, as the global exposure adjustment made the fireworks and bonfire too bright, I reduced the highlights a little bit to give the final result.

Shadow and highlight adjustment is useful in a wide range of scenarios to help balance the image out — bringing overexposed areas down in brightness, and helping to boost the shadows. Just be aware that a light touch is recommended — increasing the brightness of the shadows too much can result in a lot of noise being revealed, which might look unnaturally green or purple.

5. How to Adjust the Contrast
Contrast is about accentuating the difference between the light and dark parts of the image. Increasing the contrast of an image can dramatically improve the visual impact that has, by making the boundaries between those light and dark parts clearer.

Let’s take a look at a shot of people jumping against the sunset in the Sahara, for example, which I’ll be editing in Snapseed.

Girls jumping on sand dunes - original photoGirls jumping on sand dunes - original photo

There is nothing too wrong with this shot, but it lacks the visual impact that I wanted. Ideally, I would want the shapes of the people to be in full silhouette against the sun, but as it was shot the camera picked up some skin tones and clothing color.

Using the contrast tool, we can make the dark areas stand out against the bright areas.

And here’s the result:

As you can see, this made the jumping figures and the dune more silhouetted against the sky. In most shots, you only want to tweak the contrast a little bit to get the desired effect, normally no more than +20 or so, but in this case, the higher number gave the best result.

6. How to Adjust Colors
Color adjustment is another important piece of the editing toolkit. We can adjust image color in all sorts of ways, from changing the overall “warmth” of the image (how blue or yellow it appears), to individually changing the hue and saturation of specific colors inside of an image.

For this post, though, I just want to cover some very simple color changes you can use to make your images just a little more visually impactful.

The fastest way to adjust an image’s color is with the “Saturation” tool. This changes the appearance of every color in an image to make it more or less saturated. We can use the saturation tool to desaturate an image, eventually resulting in a black-and-white image with no color:

Or we can go all the way to the other end of the spectrum, and make the color incredibly saturated:

Photo of orange building and waterfall - neon - saturatedPhoto of orange building and waterfall - neon - saturated

As with many edits, the key is to find a good balance — oversaturated images tend to look rather unnatural. Desaturated images can be very effective, and of course black-and-white is an excellent choice for all sorts of situations, in particular, portraits, architecture, and certain landscape scenes. But generally you would want to find a happy midpoint: not too oversaturated and not too undersaturated.

Saturation is adjusted on a sliding scale and is on the basic adjustments panel in Lightroom or the “Tune Image” option in Snapseed.

7. Blemish correction
The last area I’m going to touch on today is blemish correction, or “image healing.” Sometimes there will be something in an image that you really don’t want to be there, like an inconvenient pimple on someone’s face. This is easy to remove in all the major editing tools.

You can, in theory, remove any object from a scene, but the healing tool works best on distinct, small objects that are surrounded by uniform colors. This is because the heal tool has to replace the area you wish to remove with something else, and this works best when it has an area nearby that looks similar. So for example, a pimple on a face is surrounded by a lot of similarly colored skin, so the heal tool can easily calculate what to replace the pimple based on the surrounding area.

For this example, I’m going to show how Snapseed can be used to replace an object in a scene. Here’s a group of people sitting on a sand dune in the Sahara:

Let’s say for some reason I only wanted to have people sitting in my shot, and I need to remove the standing person. She is a good candidate for removal as she is separate from the rest, and the surrounding scenery is not too complicated.

In Snapseed, we load up the healing tool, then we zoom in on the object to be removed with the standard “pinch to zoom” gesture.

Next, we use our finger to draw the area to be removed. It’s important to be as precise as possible because the tool is most accurate with small objects.

Once we have drawn the area, Snapseed will edit it out, replacing it with the best guess of what is behind the object.

As you can see, the result is impressive, with no real evidence that there was anyone standing there at all.

The healing tool is perfect for all manner of fixes, from editing out unwanted background strangers in your shot, to removing skin blemishes in portraits or power lines in landscape shots.

Best Photography Editing Software

Here is a list of the best editing tools out there:

  • Adobe Lightroom (PC or Mac) – Lightroom is the industry standard tool for photography professionals. But this post is not going to focus on Lightroom, nor cover everything you can do in Lightroom, as it’s a massively complex tool, covering both photo management and photo editing.
  • iPhoto (Mac) – I list iPhoto here mainly because it’s a commonly used tool among Apple users. However, I personally never recommend using it. While it will let you do everything that I cover in this post and is better than nothing, the way it manages your photos makes it hard to migrate to a more sophisticated system further down the line if you choose to do so.
  • Picasa (PC or Mac) – Picasa is a free desktop photo editing application from Google. It’s very simple, but it allows you to do everything I’m going to cover in today’s post. If Lightroom is a bit overwhelming, Picasa is a great, free place to start.
  • Snapseed (iOS or Android) – Another free Google tool, Snapseed is the best mobile image-editing app for both iOS and Android. It’s an incredibly powerful tool that, while simple to start using, has a great many features that take time to fully master. I use it for 95% of my mobile editing needs.

Let’s take a look now at what you can and should be using these tools for with your images.

Editing your photos is a crucial step that far too many people skip. As you can see from this lesson, there is much more to editing your photos than just picking a filter and posting your picture on Instagram. By incorporating some of these tips and techniques into your post-processing routine you’ll be able to improve your travel photography in leaps and bounds.

So get out there and start taking pictures!

Google Lens Is a Must-have Travel Tool — Here's How to Use It on Your Next Trip

Elizabeth Preske

When Google sent me to Oaxaca, Mexico to test out their new Google Pixel 3a phone, I was more than excited to play with the much-talked about Lens feature. Google Lens, an image recognition technology which enables you to "search what you see," is essentially a way for you to point your phone at anything that catches your eye and look it up on Google.

With five functions (Auto, Translate, Text, Shopping, and Dining) Lens becomes a useful and convenient tool for the curious-minded traveler, a means to learn more about the world around you.

While Pixel users can find the feature in the Camera app and Google Assistant, Lens isn't solely available on Pixel phones. If you have another Android phone, such as the Samsung Galaxy S10, you can download the Google Lens app from the Google Play Store. iPhone users can get in on the action, too, as Lens can be found in the Google app for iOS.

As a non-Spanish speaking tourist in an unfamiliar city, I found the Auto, Translate, and Dining functions in Lens particularly helpful. So if you're heading abroad and want to learn how to use Lens to make your trip easier, read on.

Auto

If you’re wandering down the street and come across a mysterious building or landmark you want to learn more about, just point your Lens at it using the Auto function. Google will fetch the info for you, sometimes with links to different websites featuring the attraction. Other times, Lens will pull up a quick summary and Google reviews in case you're itching to know whether you should squeeze one more item into your itinerary. Eager to test this tool out, I used it to learn the name of a gorgeous cathedral I passed on my way to dinner one night. A couple of quick taps on the phone and voilà: there I was facing the Basilica of Our Lady of Solitude.

The feature also works on plants, fruits, vegetables, and animals. With its abundance of foreign produce, the Mercado Benito Juárez acted as a playground for my group of seven, our phones at the ready. Directing my Lens at a display of spiky fruit, Google pulled up two results: rambutan and lychee. Although Lens could not precisely identify the fruit, the accompanying images helped me figure it out (it was rambutan).

You need Wi-Fi or cellular data in order for this feature to work, so if you don’t have Internet, take a photo anyway. Later, you can pull up the picture on your phone and press the Lens icon at the bottom of the screen. Google Lens will tell you what it is — helpful for when you’re looking through your pictures weeks later and can’t remember what the tour guide said about that building.

Translate

When you travel to a country where you don’t speak the language, Lens can help make the language barrier easier to navigate. Select the Translate function within Lens, point your phone at any foreign text — signs, menus, labels, stickers, books, you name it — and Google will translate the words in English. In an Oaxacan shop, I used Lens to read the label on a bag of coffee beans.

It might take a couple minutes to read the translation. Sometimes the text doesn't translate well, while other times the lines of translated text overlap. If that happens, just keep pointing your phone at the text: Lens periodically updates the words and sentences to make them more clear and give users a general understanding of their meaning.

If English isn’t your first language, you can opt to translate text into your preferred language (e.g. Croatian to Dutch, Polish to Greek). The feature supports 88 languages — including Swahili, Hindi, Thai, and Swedish — which can be translated into over 100 languages.

Don’t have a Google Pixel? You can download the Google Translate app and it works very similarly. One special advantage to the app is the Conversation feature. It translates your speech into foreign text, giving you the opportunity to chat face-to-face with a person who doesn't speak your language.

Dining

If you’re at a restaurant and have a hard time deciding what to choose off the menu (especially if you're in a foreign country and can't even read the menu), select the Dining feature in Lens. Google will highlight the most popular menu items at that restaurant, like the mole verde con brocoli rostizado y verduras (green mole with roasted broccoli and vegetables) at Restaurante Casa Oaxaca. When the menu is in a foreign language, Lens will even translate it into your preferred language — so you don't have to go into your meal blind.

Google Lens is available in the Camera app and Google Assistant on Google Pixel phones; for non-Pixel users, the Google Lens app is available on the Google Play Store; and iPhone users can find Lens on the Apple Store.
