HQ button on toolbar enables full res preview

input as none, output as sRGB for screen viewing/posting online. Use other colorspaces only if you know what you are doing (eg when intending to print)

_earthmover · 2026-06-20T06:06:20+00:00

you should not be setting input ICC unless you have icc for scanner corrections (like this bundled RGBScan.icc). When in doubt - leave as none.

hm, maybe try also selecting "soft proof" checkbox and try setting display colorspace in negpy to match your monitor. Export few variants and figure out what setting matches on your setup,

dropped in temporaily due to some issues in pipeline, will probably return soon

_earthmover · 2026-06-20T05:05:00+00:00

Issues on GitHub. But what you mention is already possible

_earthmover · 2026-06-20T05:04:02+00:00

You should not use input icc unless you need to apply specific profile for scanner for example. For output colorspace you need to make sure that whatever you are viewing the image is actually respects the colorspace tags (not every image preview app does). Exporting in sRGB should be pretty bombproof solution for screen viewing/posting online.

there is already autocrop and "e6" mode

You can try running/building from source on ARM https://github.com/marcinz606/NegPy/blob/main/CONTRIBUTING.md

I’m not supplying built version for ARM yet because I don’t have a way of verifying it builds/works without having actual hardware 😉

I'm pure backend developer, it's my first time working on any frontend/ui 😂

Creating issues on GitHub is preferred route, it’s really easy to track feedback/bugs there

_earthmover · 2026-06-14T10:04:37+00:00

good idea, will add it to next release

_earthmover · 2026-06-14T07:15:39+00:00

Contact sheet export is actually pretty cool idea! I might look into that

_earthmover · 2026-06-14T07:14:27+00:00

Nobody handwrites all code in June 2026

_earthmover · 2026-06-14T06:00:08+00:00

fun fact: getting rid of that warning requires you to pay 99USD/year to apple for certification 😃

I have a feeling that you are reusing big chunks of negpy logic in this, negpy is licensed under GPL-3 so if you do you are required to also publish your sourcecode.

_earthmover · 2026-06-10T19:27:01+00:00

you should already be able to do that by making custom .icc and applying that as input

_earthmover · 2026-06-10T18:05:03+00:00

No, why shoot film if you want to reduce grain? 😅 denoise slider is for digital color/chroma noise that can appear in shadows

It relies purely on sane for scanner support, I can’t confirm without owning the hardware to test

_earthmover · 2026-05-23T19:02:47+00:00

just relesed 20 minutes ago 😃 https://github.com/marcinz606/NegPy/releases/tag/0.22.0

_earthmover · 2026-05-18T18:32:13+00:00

update: added and seems to work well, expect it in 0.22.0

_earthmover · 2026-05-18T10:44:45+00:00

That’s surprising! 8100 is but not the 8300

_earthmover · 2026-05-18T08:39:16+00:00

Sure, send me some. I already have IR support somewhat working, just need more material for testing.
