Re: "chromatika"

In: s/pascal

you can try the prototype, right now it is published

โ€” 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?

๐Ÿ™ norayr [OP/mod] ยท May 13 at 23:28:

yes, sort of. that's so long to explain.

you know what is color checker? let's say you're doing product or art or architecture photography. you need to make sure that colours on your photos are the same as on the product. for that people use color checkers. that's a plate with 24 colors, or sometimes about 100 colors. we know each color should be this R, G and B. but your camera shoots it as that R1, G1 and B1. so we know that your R1, G1, B1 should become R, G and B, then the colors will be correct. same for each color, same for the colors in between those that we have on color checker.

now the same tech can be used to emulate film stocks. and it is used when people color movies let's say.

you shoot color checker under reference light, and then you see that this film, instead of this color, it gives you that color. and instead of this - that.

colors in between needs to be recalculated.

so every obscure film that i get to have, i shoot color checker with it. i shoot it under reference light, and i shoot it with different exposure to see how it reacts when there is a lack of light or there is more light.

chromatika โ€” 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...
