Blown Sunset, Five Free RAW Apps: Which Phone Editor Actually Pulls the Sky Back?
Free RAW editing on a phone is a bit like free parking in a city: it exists, but you need to know where to look and what the catch is. To test the real limits, I took the same two DNG files from a sunset shoot and ran them through five free phone editors. No subscriptions, no trial credits, no desktop round trip. Just the free tiers as of November 2026.
The files came from a 24MP Android phone DNG and an iPhone ProRAW DNG. I used the standard DNG for the cross-app test because every app opened it; ProRAW support is still uneven. The scene was a parking lot at the edge of a county park, sun dropping behind a line of trees, sky white in the middle and orange at the edges. A classic case of the phone exposing for the foreground and letting the sky go.
The test rules
I opened the same DNG in each app and used only the basic tone controls: exposure, highlights, shadows, whites, and blacks. No sky replacement, no HDR stacking, no AI masks, no healing brush. I wanted to know which app could pull detail out of the raw file with the tools a hobbyist actually gets for free. I judged highlight recovery by looking for color and texture in the bright part of the sky, not just a gray patch. I judged shadows by looking at the tree line and the parking lot asphalt. Noise was judged at 100 percent on a 27-inch monitor. Export speed was measured on the same phone with the same JPEG quality setting, averaged over three runs.
One important caveat: if a pixel is clipped to pure white in the raw file, no app can bring it back. The goal is to recover the headroom that is still there, not to invent a sunset that the sensor never recorded. That is why the underexposed file mattered as much as the blown one.
The five apps
| App | Highlight recovery | Shadow detail | Noise | Export speed | Best for |
|---|---|---|---|---|---|
| Snapseed | Strong and fast | Good | Moderate | 3 to 5 sec | Quick single-frame rescue |
| Lightroom Mobile free | Best roll-off | Good | Best | 8 to 12 sec | Control, with paywall limits |
| Photoshop Express | Decent | Soft | Moderate | 4 to 6 sec | Simple edits |
| Polarr | Good | Good | Aggressive | 6 to 8 sec | Slider tinkerers |
| Darkroom | Good | Very good | Good | 4 to 6 sec | iPhone library workflow |
Snapseed was the surprise winner for speed. The Highlights slider pulled color back into the orange edge of the sky without turning it into gray mush. The Shadows slider opened the tree line, though the noise reduction is not subtle. Export was fast and the app never asked me to sign in. For a single frame that needs a quick rescue, it is hard to beat.
Lightroom Mobile free had the best highlight roll-off. The gradient from white to orange stayed smooth, and the shadow recovery was cleaner than Snapseed. The catch is the free tier. Basic tone controls are there, but masks, healing, and some of the more useful local adjustments are behind the subscription. If you are willing to stay in the basic panel, it is excellent. If you want to dodge and burn the sky, you will hit the wall.
Photoshop Express was the easiest to use and the least impressive on the sky. It recovered some detail, but the highlights went flat and the shadows got soft. For a quick social post, that is fine. For a print or a portfolio frame, it is not the tool I would pick.
Polarr gave me a lot of slider control and a good starting point for the sky. The noise handling was aggressive, though. It smoothed the tree line into a watercolor texture when I pushed the shadows. If you like to tinker and you do not mind a little grain, it is a solid free option.
Darkroom was the best fit for iPhone shooters who already live in the Photos app. The highlight recovery was close to Lightroom, the shadow detail was clean, and the export was quick. The free version has limits, but the basic workflow feels native and fast. If you shoot ProRAW and want to stay on the phone, it is the most pleasant experience of the group.
The recovery order that worked
Start with highlights, not exposure. Pull the highlights down until the sky stops looking like a light box. Then adjust exposure slightly, then lift shadows. If you lift shadows first, you will usually make the sky look worse and the noise more obvious. Add a little whites back if the image looks flat. Use a local gradient on the sky if the app allows it. Save noise reduction for last, and do not overdo it. A little grain is better than a plastic tree line.
For the underexposed file, the order flips a bit. Raise exposure first, then shadows, then highlights. The goal is to keep the sky from clipping again while opening the foreground. Every app handled this differently, but Lightroom and Darkroom kept the most color in the sky. Snapseed was faster but slightly harsher.
Which one actually recovers the sky
If you want the best highlight quality and you can live with the free-tier limits, Lightroom Mobile is the winner. If you want the fastest no-account rescue, Snapseed is the winner. If you shoot on an iPhone and want the whole thing to feel like part of the camera roll, Darkroom is the winner. Photoshop Express is fine for casual edits, and Polarr is for people who enjoy sliders more than speed.
The bigger lesson is that free RAW editing is not about one magic app. It is about knowing the order of operations and knowing when the file is actually clipped. A recovered sky should still look like evening. If it looks like a gray HDR mistake, you went too far. The best app is the one that lets you stop before that happens.
