The first five editing adjustments every photo can use
Editing is not about making a photo look fake; it is about finishing what the camera started. Five basic adjustments, done in a sensible order and with a light touch, improve almost any picture: crop and straighten, exposure, highlights and shadows, white balance, and contrast. You can do all of them in the editor built into your phone or in a free desktop program. This guide explains each step, why RAW files give you more room, how to avoid over-editing, and how to export for the web.
A light-touch starting point
| Adjustment | Typical range | Section |
|---|---|---|
| Straighten | Level the horizon, usually under 3° | 3 |
| Exposure | About ±0.3 to ±1 stop | 4 |
| Highlights / Shadows | Highlights down, shadows up, small amounts | 5 |
| White balance | Small temperature and tint shifts | 6 |
| Contrast / Clarity | Low single digits to about +20 | 7 |
| Vibrance vs saturation | Prefer vibrance, about +10 to +20 | 7 |
| Web export | sRGB JPEG, about 2,000 px long edge | 9 |
1Work non-destructively
Non-destructive editing means the original file is never changed. The editor stores your adjustments as a list of instructions and applies them when it shows or exports the photo. You can undo any step, try another version or start again months later.
Most phone editors and almost all photo-library programs work this way. Pixel editors that save over the file do not, so in those, save a copy first.
- Use an editor that keeps the original and lets you revert (phone gallery editors, darktable, RawTherapee and most photo libraries do).
- If an app saves over the file, duplicate it before editing.
- Use virtual copies or versions to compare two treatments side by side.
- Keep your originals in your backup routine; edits can always be redone, lost originals cannot.
2Why RAW helps
A JPEG is already processed in the camera: white balance, contrast and sharpening are baked in, and much of the extra tonal information is thrown away. A RAW file keeps the sensor data with more bits per channel, so you can recover highlights, lift shadows and change white balance with fewer side effects such as banding or colour shifts.
JPEGs can still be edited well, especially if they were exposed carefully. RAW simply gives more room when a scene was difficult.
- Shoot RAW (or RAW plus JPEG) when light is tricky: high contrast, mixed light or low light.
- Expect a RAW file to look flatter before editing; that is normal.
- On a phone, look for a RAW or pro option in the camera settings if you want the same latitude.
- Make bigger exposure and white balance changes on RAW files than you would on JPEGs.
31. Crop and straighten
Start with the frame, because cropping changes what the editor and your eye treat as the whole picture. A tilted horizon is one of the most noticeable faults in a photo, and a slight crop can remove a distracting edge or tighten the composition.
Every crop throws away pixels, so crop with purpose rather than heavily, especially if you may print large.
- Use the straighten or angle tool to level the horizon or a vertical edge such as a building.
- Crop away distractions at the edges: a stray branch, half a person, a bright spot.
- Keep a standard aspect ratio (3:2, 4:3, 4:5 or 1:1) unless you have a reason not to.
- Use the rule-of-thirds overlay as a guide, not a rule.
42. Set the overall exposure
Exposure (or brightness) moves the whole image lighter or darker. Get the overall level right before fine-tuning bright and dark areas, because every later adjustment depends on it.
The histogram helps here: a pile-up against the right edge means clipped highlights, against the left edge means blocked shadows.
- Adjust exposure until the main subject looks naturally bright, usually within about ±1 stop.
- Check the histogram and avoid pushing important tones hard against either edge.
- Judge on a screen at moderate brightness; a phone at full brightness makes photos look brighter than they are.
- Leave intentional moods alone: a night scene should still look dark.
53. Balance highlights and shadows
These two sliders work on parts of the tonal range. Lowering highlights brings back detail in bright skies and white clothing; raising shadows opens up dark areas without brightening everything.
Pushed too far, they flatten the photo into a grey, low-contrast look, and strong local tone changes can create halos: bright or dark glows along edges, such as a light band where a dark tree meets the sky.
- Lower highlights until the sky or bright areas show texture again.
- Raise shadows gently; stop as soon as the dark areas show the detail you need.
- Zoom in to 100 percent along high-contrast edges and back off if you see halos.
- Use the whites and blacks sliders, if available, to restore a little punch afterwards.
64. Correct white balance
White balance decides whether neutral things look neutral. Indoor bulbs often make photos too orange, shade and overcast skies make them too blue. The temperature slider moves between blue and yellow; tint moves between green and magenta.
Correct does not always mean neutral: a sunset is meant to look warm. Aim for colours that match what you remember or the mood you want.
- Use the eyedropper on something that should be neutral grey or white, then fine-tune by eye.
- Check skin tones: they are the colour people notice first when it is off.
- Make small moves; a little warmth or coolness goes a long way.
- With RAW files, choose a white balance preset (daylight, shade, tungsten) as a start.
75. Contrast, clarity, vibrance and saturation
Contrast stretches the difference between light and dark across the whole image. Clarity (sometimes called structure or local contrast) adds contrast to mid-tone edges, which brings out texture. Both are effective at small amounts and harsh at large ones.
Saturation boosts all colours equally, which quickly makes skin look orange and skies look neon. Vibrance boosts the weaker colours more and protects already-strong ones and skin tones, so it is usually the safer choice.
- Add a small amount of contrast, roughly +5 to +20 on a typical slider.
- Use clarity sparingly; avoid it on portraits, where it exaggerates skin texture.
- Reach for vibrance before saturation, and keep both modest (approximately +10 to +20).
- If colours start to look like a postcard, reduce saturation rather than adding more.
8Avoid over-editing
The most common beginner mistake is doing a little too much of everything. Each step looks better on its own, but together they create crunchy textures, glowing halos, grey skies and unreal colours. Eyes also adapt during editing, so a heavy edit starts to look normal after a few minutes.
- Toggle the before and after view often.
- Take a short break, then look again with fresh eyes before exporting.
- Once you are happy, try reducing your strongest adjustment by a third.
- Watch for halos, banding in skies and noisy shadows when zoomed in.
9Free tools and export settings for the web
You do not need paid software for these five steps. The editor built into your phone's photo app covers all of them. On a computer, the photo app that comes with the operating system handles basic edits, and darktable and RawTherapee are free, open-source programs that develop RAW files with professional tools.
For the web, export a resized copy and keep the full-size original. Browsers and phones expect sRGB colour; other colour spaces can look dull online.
- Export as JPEG in the sRGB colour space.
- Resize to about 2,000 px on the long edge for websites and social media (roughly 1,080–1,440 px is enough for many apps).
- Use a quality setting around 80–85 percent; it is usually indistinguishable from 100 at a fraction of the size.
- Remove location data from the metadata if you do not want to share where the photo was taken.
Before you export

- Horizon straight, edges clean
- Exposure checked on the histogram
- Highlights and shadows balanced, no halos
- White balance and skin tones natural
- Vibrance before saturation, both modest
- Before and after compared
