this is the source of my pascal app. i am writing it by using delphi community edition, because it is able to build same source for android and ios, also for windows and macos.
the app has 4 hald cluts as resource files. those are taken from real film stocks. to apply hald clut i had to implement the algorithm, and only hald clut implementation took one week. at some point i was desperate, thought i cannot do it.
so the 'presets' are chrome, warm, cold, landscape. those are actually luts of kodachrome, old kodak ektar, fuji astia and velvia. kodachrome does not exist now, but i have found a color checker photo made with kodachrome. of course we dont know if scanner was calibrated etc. but the result looks surprisingly kodachrome-ish. i love that preset.
the main incentive to write this app is that my friends make photos with phones, and my eyes don't enjoy digital colours. so i wanted to give them a tool which has to be simple to use, and which doesn't provide lots of settings or choice.
i was even thinkin of an app with only one button: 'make beautiful'. but i guess, these four presets cover most of cases of photos.
velvia 50 is great for landscapes, but adds a bit red, so not always great for portraits. but i specifically love velvia 50, and not later released velvia 100, though it is of course also great.
so 2 kodak films and two fuji films, that should be enough.

I once spent a year calibrating a Hell drum scanner...

you can try the prototype, right now it is published
— my server's directory for unsorted, temporary files.
if you risk to try the prototype, i cam ensure you, it is built from the source which is in github, but well, i understand if you won't trust me and be cautious about installing random stuff. anyway, if you decide to try, you need chromatika64.apk for aarch64 (most likely your phone is running 64bit arm) and chromatika32.apk if you have a armv7. but i guess if that's the case, it most likely doesn't have recent enough android for the sdk version delphi 11 uses by default.
it would be great to get some feedback. i know the ui feels not contemporary.

later i will also port the source to freepascal and package the app for mobile linuxes, for maemo leste certainly.
Can you tell us exactly what it is and does? I am a little confused. Does it take any imagen and 'Kodachrome' it?
