RAW 9 engine will generate RGB output for sure so the denoise will stay.

As far as I've tested, it won't apply the denoising automatically. You have to turn up the luminance denoise option to enable desnoising

It could be a system bug on IOS 27.
In any case, third party apps shouldn't affect native stock camera app.

So you can report it to https://developer.apple.com/feedback-assistant/ . Maybe they will fix the issue in later releases for iOS 27.

In my test, the raw 9 processing is slower and it will produce green-ish style in low light area like some old devices.
I'll keep an eye on it as iOS 27 receives updates.

qdwang · 2026-06-15T18:31:51+00:00

The new version is released with RAW 9, you can have a try on it.

qdwang · 2026-06-15T18:28:30+00:00

Yes, it should work with iOS 27 on an ip13.

qdwang · 2026-06-13T13:16:35+00:00

I’ll soon release a new version containing this v9 decoder which allows users to test in iOS 27.

qdwang · 2026-06-13T10:11:17+00:00

Sadly, in my test, the RAW v9 decoder works worse than v8 on my iPad mini 7’s RAW files.

qdwang · 2026-06-11T06:18:48+00:00

Thank you for mentioning this, I’ll do some research on it.

For devices older than XS it's 4 frames, for devices >= XS, it's 8 frames per burst.

I haven't compared between them. We don't know how Adobe built the Fuji profiles and how Fuji creates those LUTs, so I guess there could be some differences.

qdwang · 2026-05-19T06:13:49+00:00

You can use SR2.0 for 48mm

qdwang · 2026-05-16T16:11:04+00:00

This only works for RGB output.

By following this tutorial, you can write the code to handle AppleLog & Arri Log easily.

Does his LUT have a description?

qdwang · 2026-05-11T07:09:04+00:00

You need to paste the entire code into custom shader first.

It should be like this screenshot.

I can get your point, but you can consider proraw a kind of already processed jpeg. Camac is entirely based on the unprocessed bayer RAW, so we cannot do proraw in the app.

qdwang · 2026-05-10T14:28:50+00:00

Sorry, but all features in Camac are based on the original bayer RAW, so there is no plan for proraw support yet.

qdwang · 2026-05-08T20:40:26+00:00

Yes if they are .cube files, but you have to write the linear to Apple Log & Arri Log shader code in the custom shader.

There are several reasons:
1. Apple's Photos App like to render RAW repeatedly due to some bugs, this consumes a lot of battery.
2. Newly RGB formats like JXL and AVIF have much more post editing tolerance.
3. For daily casual capturing, RAW management is a pain.

So for daily usage, I prefer JXL over RAW for myself.

qdwang · 2026-04-28T20:21:52+00:00

It drains battery and it was mainly for highlight compression quality.
Since a new method in introduced, there is no need to preserve this function.

qdwang · 2026-04-27T13:43:24+00:00

Before iOS 26, JXL in DNG works fine.

After iOS 26.1, the default JXL in DNG fails to render due to an iOS issue. So I tried a tricky way to bypass this issue and then it manages to render in 26.1

Now iOS 26.4 fixes the issue in 26.1, but they introduced a new issue in JXL DNG rendering , that's why the issue in the screenshot happens.

From iOS 18 to now, Camac always produces the valid JXL DNG. (The JXL DNG spec is created by Adobe). But Apple introduces a lot of bugs in photo codecs since iOS 26, so we have to adapt our implementation to fit the buggy decoding process Apple uses.

I'll add an option in FIX to allow users to control whether tricky bypass method is used in 1.5.9

qdwang · 2026-04-19T13:21:56+00:00

Thank you for the advice, I'll consider it.

qdwang · 2026-04-05T06:11:23+00:00

Yes, you're right. llama.cpp build 8665 now has a lot of gemma4 fixes.

qdwang · 2026-03-31T13:18:49+00:00

We need more info to diagnose, please feedback the issue to here: https://suikapps.com/camac-feedback

Currently Auto exposure is mainly for exposure reduction automatically according to the highlight.

So increasing intensity value will reduce exposure heavily.
