A simple Snapseed edit from start to finish

Snapseed is a free photo editor from Google that runs on iPhone and Android. It has a steeper learning curve than Instagram’s filters and a shallower one than Lightroom, which makes it a good middle choice for anyone who wants to tidy their phone photos without subscribing to anything. This piece walks through one edit, in the order we would do it, and stops at the step where most people start overdoing it.

We are editing a photograph of a town square on an overcast afternoon: a little flat, a little cool, a slightly skewed horizon, one bright street lamp that pulls the eye away from the subject. Nothing clever; just the sort of file that improves a lot with five minutes of care.

Step 1. Open with a plan, not with a filter

Open the picture and resist the temptation to tap “Looks”. Instead, look at the file for a moment and name, out loud, the two things you want to change. In our example: the horizon is tilted, and the overall image is cool. That is the whole edit; everything else is noise.

Step 2. Crop and straighten

Tap Tools → Crop. Choose a ratio that suits where the picture will live: 4:3 for your camera roll, 1:1 for Instagram, 16:9 for a phone wallpaper. Trim a little from the edges to remove any stray clutter, then tap the tick.

Open Tools → Rotate. Snapseed usually offers to straighten automatically; if it looks right, accept it. If it does not, drag the small ruler at the bottom of the screen a degree or two. Zoom in and check a window frame or a lamppost against the edge of the screen; the eye is a better judge than the auto-level.

Step 3. Tune Image, slowly

Tools → Tune Image is where the real edit happens. Slide a finger up and down to change which slider is active, and left and right to change its value. Our usual order:

• Brightness: +5 to +15 for a dull daylight shot, less for anything already well-exposed.
• Contrast: +5 to +15. Overcast British light often wants a little contrast added back.
• Saturation: keep it between −10 and +15. More than that and faces go orange.
• Ambience: −10 to +15. This is Snapseed’s own invented slider, a cross between contrast and shadows. Push it gently, then back off a touch.
• Warmth: for our cool town-square scene, +10 to +20 puts the warmth of a cloudy afternoon back where it belongs. For a scene shot in tungsten light already, do not add warmth.

Tap the tick. If at any point the picture looks like an advert for toothpaste, step back one slider and reduce it.

Step 4. Fix the one thing that still bothers you

This is where most beginner edits go wrong: they try to fix everything with the global sliders and the picture becomes muddy. Instead, use Snapseed’s Selective tool. Tap Tools → Selective, drop a dot onto the bright street lamp in our example, pinch out to set the area, then swipe down to Brightness and left to dim just that patch. Repeat for any other hot spot. One or two dots is almost always enough.

Step 5. Lift the shadows, gently

Back in Tune Image, slide down to Shadows and raise it by +10 to +25. This brings back detail in the darker parts of the scene (the doorway of a shop, the underside of a tree, the shaded side of a face) without brightening the whole picture. If the photograph already had pleasant deep shadows, leave this alone.

Step 6. Sharpen, almost nothing

Tools → Details → Sharpening. +15 is more than enough for a screen. Anything above +30 starts to create halos and crispen the dust on the sensor. Skip this step altogether for portraits; it is unflattering.

Step 7. Save, don’t overwrite

Tap Export → Save a copy. Snapseed stores the editing recipe non-destructively, so you can come back and change your mind later. If you ever use Export → Export, which bakes in the edits, keep the original somewhere safe first. A photograph you re-edit six months later is usually a better photograph than one you edited in a rush at the time, and the only way to re-edit is to have the un-flattened original.

Common mistakes to avoid

• Pushing Saturation and Warmth together. Pick one.
• Sharpening a noisy night photo. It sharpens the noise.
• Using the “HDR Scape” filter on anything but a dull daylight landscape. It cooks faces.
• Fixing a bad photograph with a heavy filter. Usually the picture needed a different composition, not an edit; see our piece on composition.

A second-pass checklist

Before you close the file, run a quick second look. Hide your thumb over any face in the picture and check that the rest of the frame still holds up on its own; a face can carry a photograph for a few seconds before the eye starts reading the background, and a messy background is where most average pictures go wrong. Zoom in to 100 per cent on one corner of the frame and look for the tell-tale signs of overcooked editing: pale halos around branches, blocky colour transitions in the sky, skin that has turned the colour of fake tan. If any of those are there, undo one slider at a time until they disappear.

When Snapseed is not enough

If you start finding yourself opening the same picture several times, or editing dozens from a single afternoon, it is probably time to try Lightroom Mobile. For now, five minutes in Snapseed, once, on the three or four pictures you really like from the day, is a better habit than twenty minutes on everything. Pair it with the phone-camera tips and the notes on light, and the raw material will already be halfway to good.
