Intro: How to Enhance and Improve Your Holiday Photos

Taking holiday photos is fun, whether we're enjoying a month at a luxurious resort on a tropical island or spending a weekend running around a busy European city in the middle of Winter. Despite the large volume of pictures I usually come home with, I'm often underwhelmed with the results. What I thought was a beautifully composed night shot turns out to be an array of orange blobs floating in a sea of darkness, and the vibrant colours of the ocean, sky and foliage look lackluster in comparison to my memories.

In the past, I've often flicked through the numbered folders on my camera's memory card and discounted the majority of my pictures, simply because they don't impress me at first sight, even though I was convinced they were brilliant at the time I took them.

If this sounds familiar, then I hope this tutorial on post-processing will help. I'm not a professional photographer and there will be people out there who can give far better technical explanations of what I'm about to show you, but if you're an amateur like me and you're looking for a simple starting point to really give your holiday pics some personality, then I think you're in the right place.

Step 1: Prerequisites

For this tutorial I'm going to use the GIMP photo editing software. It's an open source project, and seems to be the go-to option if you want to do technical image enhancement without spending any money. Alternatively, if you'd like to use a truly professional tool, I'd recommend either Photoshop or Lightroom from Adobe. They aren't exactly the cheapest route, but if you invest in either of these highly popular pieces of software, you should be set for life. Finally if you're on a Chromebook, Polarr is a good option which emulates the look and feel of Lightroom. The steps in this tutorial are written with GIMP in mind, but it shouldn't be too hard to find the equivalent tools and menus in the other programs.

I'll use the above photo taken on a 2013 trip to the Grand Canyon to illustrate each step in the workflow. This is a good example because we all know how this world famous landmark ought to look, with its layered walls of brown and orange rock towering above the Colorado River. The ground, sky and distant people in the shot are also framed in a way which makes the picture interesting to look at. This photo was taken using a Canon 1100D DSLR camera and the stock 18-55mm lens that came with it. Since I bought this camera, it has been improved and refined to become the 1300D. If you're looking for a versatile piece of kit at a decent price, I can highly recommend this product line from personal experience.

A DSLR gives you immense control over every aspect of how you take your photos, and for night-time/low light shots I do like to make use of the ability to manually choose aperture, shutter speed and sensitivity. For most daytime shots though, I honestly tend to use the auto or semi-automatic (AV, TV) modes which let the camera decide most of these settings for me. I think my Grand Canyon image was taken in full-auto mode and saved directly to JPEG. You can also shoot in RAW with a DSLR, which will give you a higher quality result at the end of your edit, but the image file sizes will be a lot bigger. I normally take a large memory card with me so I have plenty of room to experiment. Here's a useful video which highlights a few situations when using RAW might be the best option.

Step 2: Getting Familiar With Levels

OK - time to start giving our test image a makeover. Once you've opened it in GIMP, our first stop will be the Levels tool. This can be found in Colours -> Levels. You should be presented with the above dialog showing a couple of sliders below an undulating chart.

This chart is called the histogram and it appears in a great many places within any photo editing software. We'll be seeing it again later in this tutorial too. The histogram is a condensed representation of the entire image and it shows how many pixels across your whole picture fall within certain brightness ranges. If it peaks towards the left side, this means that the image is mostly dark and could be underexposed. A peak towards the right means that there are lots of very bright pixels, possibly telling us that the image is overexposed.

The important slider in the Levels tool is right below the histogram in the area labelled Input Levels. There are 3 little pointers here which, when moved left and right, will drastically change the contrast and overall brightness of the image. You will be able to see these changes in real-time if you have the Preview option checked.

Step 3: Adjusting Levels

The first things to notice are the gaps at each end of the histogram which tell us that the image contains no pixels which are 'completely dark' or 'completely light'. This often signifies a lack of contrast and is one of the easier problems to fix. If you drag the pointers on the left and right of the Input Levels slider so that they're closer to the corresponding visible edges of the histogram, you will see an immediate difference in the picture - dark areas will appear darker and vice-versa for bright areas.

Once you're happy with how the dark/light areas of the image look, you should adjust the middle pointer (or 'mid-tones') on the Input Levels until you're satisfied with the overall brightness shown by the preview. This is largely subjective as some images will need to be brightened and others will need to be darkened in response to how you've adjusted the other two pointers. I was happy with the above final values for the input levels on my test image.

Press OK to close the dialog and apply the results.

Step 4: Getting Familiar With Curves

Levels are fine for adjustments which broadly affect the overall image, but sometimes we want to finely target specific areas of light or shadow and boost/subdue them further. This is where the Curves tool comes in. This can be found in Colours -> Curves. You should be presented with the above dialog which again contains the histogram, this time showing a linear curve cutting across it.

Note that the histogram looks different to when we first saw it in the Levels tool - this is because the changes we applied in the previous step have affected the overall distribution of pixels between light and dark. The concept of our new histogram is still the same though - it shows how the brightness of all the pixels in our image stacks up, with those on the left being 'completely dark' and those on the right being 'completely light'.

So what does that linear curve across the histogram do? If you click on it, a node will appear which allows you to drag the curve into a new shape. If the Preview box is checked, you should see the image changing too as you drag and drop the node. Can you work out how the curve affects the image?

Step 5: Adjusting Curves

If you pull the curve down, the picture will become darker overall while pulling the curve up will cause it to become brighter. Dragging a certain area of the curve above/below its default linear position will brighten/darken respectively the associated pixel values in the histogram. In practise, this means that dragging the left side of the curve down will darken the shadows, while moving the right side up will lighten the brightest parts of the image.

If you click on the curve more than once, a new node will be created at each chosen point. They can all be dragged independently which lets you fine-tune which areas are brightened or darkened. A typical curve which instantly improves many photos is the S-curve, where the left side is pulled down, the middle remains in place and the right side is pulled up. As per the above explanation, this will darken the shadows, leave the mid-tones more or less the same and brighten the lightest areas. This is effectively what we did with the Levels in the previous step, so a full S-curve would probably be overkill here.

Instead, we will use the curve to fine-tune any areas which we aren't 100% happy with after our levels adjustment. Again, this is largely subjective but I find that subduing the very darkest areas and subtly boosting the brighter areas can still add a slight improvement. I went with the above shape for the curves on my test image.

Press OK to close the dialog and apply the results.

Step 6: Getting Familiar With Colour Balance

Up to now, we've been obsessed with histograms and the relationship between bright and dark. If we were shooting in black and white, this would almost be the end of our story but of course we didn't go all the way to the Grand Canyon to not capture the beautiful colours! While our image definitely contains some striking scenery, it still isn't much to look at when you put it beside the cover of a travel magazine showing the equivalent. Our colours look boring and washed-out in comparison and our photo still doesn't give off the warm feel that you'd expect from the Arizona desert.

This is where the next tool comes in - Colour Balance. This is not always needed, and how you use it definitely depends on gut feel. I applied a small change in the test photo so I'll quickly go through my thoughts. First, open the Colour Balance tool through Colours -> Colour Balance. You should see a bunch of sliders with different colours named at either end, as above.

Step 7: Adjusting Colour Balance

This tool is useful if you feel that your image is incorrectly tinged with a particular colour, for example a photo taken indoors might look too blue or you might notice that someone's skin appears too green due to the lighting or surroundings. If you do notice a problem like this, simply pull the relevant sliders AWAY from the colour that you want to reduce. You can mix the sliders to boost or subdue a combination of their primary colours and you can choose whether to modify the shadows, mid-tones or bright parts of the image using the buttons at the top. This tool normally only needs subtle tweaks and I find that I only really need to work with the mid-tones here.

For the test image, I went with the above simple adjustment which I feel made the colours of the distant terrain look a bit more 'ground-like'. I know that's vague for a tutorial but it really is down to your own eye as to what the correct balance is.

Press OK to close the dialog and apply the results.

Step 8: Getting Familiar With Saturation

Next, we will look at one of the most important colour tools which can make even the most boring raw picture look more exciting - Saturation. Open the relevant tool by selecting Colours -> Hue/Saturation. You should see a dialog like the one above, with yet more sliders underneath a circle of colours at the top.

Saturation refers to the intensity and overall dominance of the colours. When we look at our test photo, we can of course see that the sky is blue and the rocky terrain is a brown-orange shade. However, the colours don't appear to have much impact or variation, and the image looks fairly uninspiring when we compare it to something that a professional photographer might take in exactly the same location.

When we move the Saturation slider, we are adjusting how close each colour is to its 'pure' value. When the colours become more saturated, their vividness in comparison to each other will increase. On the other hand, if we de-saturate the colours, the image will become more and more gray until eventually all hint of colour is lost.

Step 9: Adjusting Saturation

To start with, we will play with the bottom Saturation slider. Making sure that the Preview box is checked, try moving the slider to the right and watch how the important colours start to jump out. If you move the slider all the way to the left, the image will be reduced to grayscale. It's easy to overdo Saturation, so try gradually pushing the slider to the right until you get a good result.

You have just changed the master Saturation which affects all colour channels across the whole image. If you want to enhance only certain colours while leaving others softer, you can select them individually from the circle at the top. You can also get arty here and de-saturate particular colours so that certain sections of the image appear grayscale while others still show up in colour. In the test image, I decided to push cyan a bit higher so that the sky would have slightly more colour to it. Above are the settings I decided on for master and cyan (in that order).

Press OK to close the dialog and apply the results.

Step 10: Finish Off With Some Sharpening

As a reward for getting this far, the final step is nice and easy. We will apply a tiny bit of sharpening to the image to enhance the boundaries and lines between light and shadow. Like saturation, this is a universal step which can improve almost any holiday photo. GIMP has a pretty powerful sharpening tool which you can access via Filters -> Enhance -> Unsharp Mask. It looks like the window above.

There are quite a few options here, but I find that similar settings can be used for the majority of simple photos. I tend to set the Radius between 2 and 5, and then play with the Amount until I see a result which is a subtle improvement overall, but doesn't make the more detailed parts of the image look too 'spikey'. You can use the Preview window to find a point in the photo which contains a boundary or some small details, and then adjust the Amount until you're happy. Start low and ramp it up.

For the test image, I went with the above Unsharp Mask parameters. Press OK to close the dialog and apply the results.

Step 11: Summary

If you've been following these steps exactly, you will have seen the image change bit by bit, improving with each new adjustment. The only way to really see what we've done is to take a look at the final result above, with all the adjustments.

That's quite a difference! It puts a new perspective on just how desperately the original needed some attention. It also shows the sort of details that can be teased out of a simple 'point and shoot' photo which took very little effort to compose. Just think what you could do if you had the time to experiment with all the settings on your camera, or even just use a semi-automatic mode which gives you priority control over the shutter or aperture.

Here's a summary of all the steps we've been through here:

  1. Adjust the dark/bright Input Levels sliders relative to the histogram edges to improve contrast. Adjust the mid-tones slider to settle on the overall brightness.
  2. Apply a subtle curve adjustment to enhance any areas along the brightness scale we're still not happy with.
  3. If you think there's a nasty tinge to your image, balance it out using the Colour Balance tool.
  4. Increase the master saturation and also adjust the saturation for any other colours you want to emphasise further (or de-emphasise).
  5. Apply some sharpening, being careful not to make edges look too 'spikey'.

There's also this really cool feature on Lightroom if you have it, and Polarr should too. It's called "dehaze," and there's a lot of cool things it can do. It can increase contrast in wood and rock, so you can see the grain and layers a lot better. It also helps with getting that perfect blue sky, and enhancing the clouds so they don't just look like fluffy white blobs, but have those cool shapes that we see with the human eye.

I use the built in photography editor/enhancer on my Windows computer which works pretty well. but I've heard you can make a preset in Adobe Illustrator illustrator and apply it to all of your photos, to save a ton of time.

Yeah, a lot of programs come with an 'auto enhance' option. Sometimes it gets pretty close!

I use that sometime too, but I was referring to something else, a preset that you make, and then you can "paste" it onto all of your photos, so you don't have to edit each one manually.

It probably doesn't turn out as good, but you can always edit them later anyway. All photos always lack bit of brightness, saturation, and sharpness :)

Nice job! Another program that is very similar to photoshop, but much much cheaper is Affinity Photo. I've been using it for a while now, and multiple pro photographers on Youtube says that it is on par with Photoshop.

If you do want to go with Adobe software, an alternative that can be used purely for adjustments like this, is Lightroom.

I've just got Affinity Photo and I'm really pleased with it. I don't like the licencing model that Adobe use now for work that I might want to revisit in the future.

The only downside I've seen of Affinity is that the Develop persona (RAW editing) doesn't seem to be non-destructive. You can't reopen a developed image and modify the editing stages used previously.

It's also available for iPad now at only $29 which is a bargain.

if your camera can shoot in RAW then use it for contrasty shots like this. There is much more info recorded that a jpg looses. You can do HDR from 1 RAW.
