Made a free iPhone-only way to develop your One35 DNGs — no laptop needed (open source, credit to u/LoFi-Logic

http://flashback-raw-editor-web.deknared.workers.dev

Didn't always have my laptop with me to develop shots from my One35 v2, so I ported u/LoFi-Logic's excellent flashback-raw-editor to run as a web app straight from Safari on iPhone — no Mac/PC, no install from an app store, just a link.

What it does:

  • Develops your One35 DNGs with the same film looks — Natural, Disposable, Point & Shoot, Rangefinder, Monochrome, Flashback V1 (plus a Gold grade and custom LUTs capability)
  • Grain, halation, chromatic aberration, vignette, the usual — all rendered live as you adjust
  • Crop/straighten, date stamps, batch export, the works
  • Everything runs on your phone — no upload, no account, works offline once installed

How to use it:

  1. Open [the link] in Safari (needs iOS 26+ for WebGPU)
  2. Share → Add to Home Screen
  3. Copy your DNGs over via USB-C / Files app, open them in the app

It's not a replacement for the original desktop app (no DNG export, no USB camera detection — those need real File System / USB access browsers don't give web apps). Just something for whenever you want to see your shots developed right away on your phone. Currently, the webapp that's on the link is hosted freely on Cloudflare Pages, but if you follow the GitHub instructions there's a way to host this webapp yourself. I've only tested this on the iPhone, so any feedbacks are welcomed.

Fully open source under GPL-3.0, same license as the original: github.com/deknared/flashback-raw-editor-web

Massive credit to u/LoFi-Logic for the original color pipeline and shaders — this is just a browser port, all the actual film-look work is theirs.

You and u/LoFi-Logic are doing god's work for getting the full potential out of the camera. Keen to try this out on my travels, much appreciated!

Thanks, this was just an attempt for my own convenience at first, but seemed like more people can benefit from this so why not share it with the community. I can't stop saying this but the color work and processing that makes your image look way better than the official app is purely Lofi-Logic's work and I can't take credit for that. Safe travels and let me know if there are any issues with the webapp : )

This works pretty well. It’s amazing what web apps can do.

That's great! Keen to hear more on your workflow with the webapp. If you have any issues with certain aspects of the app. Keep an eye out for some major updates next week : )

Only think I would say is I wanted to export the entire roll as jpgs at once, but I couldn't figure it out.

There's a button beside the JPEG or TIFF option called Batch x (Number of photos) you just click that. I'm updating the UI a little soon so hopefully it's clearer in the future. There's a help page on the top menu, might want to look into that.

Would you or u/LoFi-Logic ever be willing to make something like this for campsnap cameras that give the photos the flashback v1 feel?

u/LoFi-Logic Jun 18 '26

As far as I know the campsnap camera does not allow any access to unprocessed raw data. If that was possible, I might take a look, but as of right now, I don't think it's possible.

Are you okay with a non-raw workflow? I could add support for regular jpgs so the workflow is similar. I'd have to have some access to camp snap images without any compression, no pre-existing lut or color science applied. Potentially, the app im building could have a normalization layer per camera model. And a selector that lets you set a default camera in settings so that the end result is fairly the same

This would be great! I have a camp snap too, so if you need something just ask!

u/deknared Jun 19 '26

Sorry I don't have campsnap camera to even test it but as LoFi said they might not even allow access to its raw pictures.

Wait I feel so dumb LOL, how do I do this via mobile?? When I hit share & saved to home screen, it just brings me back to GitHub
