Show HN: Toned, an iPhone darkroom app that models film negatives and paper

from the show-hn dept.

I am interested in simulating pyshical processes in software so i decided to build an iPhone app that simulates film negatives and paper.It models in 2 stages: scene light -> color negative -> print reflectanceThe negative uses per-dye-layer H&D curves and the paper also has its own response curves.If you've ever spent time in a real darkroom, I would really like you to try the app...

That’s actually pretty close to what I ended up building.

For the first one, I skipped the map and went with search + saved cities instead. All your saved places sit on the same 24-hour dial, so you can see the difference from your local time at a glance without doing the timezone math. The upside is that it works completely offline and fits nicely on Apple Watch too.

Your second suggestion is the part I only got halfway right. You can move the dial in 15-minute increments and the daylight/twilight colouring changes with it. There’s also a calendar where you can jump to any date and time and see what the solar state is in every saved city, but right now that’s shown in rows rather than by recolouring the clock itself.

I like your version better though, hovering/scrubbing a time and having the whole clock recolour for that moment would make a lot more sense. I’m going to add that to the list.

I’m the developer, btw: https://apps.apple.com/app/id6797192832

Show HN: Glimpse, Markdown reader using Apple's on-device foundation model

https://apps.apple.com/us/app/glimpse-markdown-viewer/id6761304904?mt=12

Glimpse is a native macOS markdown viewer. The thing I built it around: the AI features run entirely on-device through Apple's FoundationModels (the same model behind Apple Intelligence). Summaries, key insights, an auto-glossary of jargon in whatever you're reading. Nothing leaves your machine, no API key, no account.I read long markdown all day, mostly engineering docs and RFCs, and...

Re:Turkey bans use of cryptocurrencies for payments on Friday April 16, 2021 @07:09AM (#26832400)
As a Turkish citizen I can say that the real inflation is much higher than 17% but they are trying to make it look lower by changing the formula constantly so they don't have to raise government employee's salaries so much. I would say the real inflation is closer to 50%.

There is nothing wrong with charging different prices for different countries. The problem is I'm living in Turkey most of the time and my bank is a Turkish bank but I have been charged in Polish Zloty all these time. I don't think they would let me pay less if I created my account in a country 2 years ago where price was 2,5 times cheaper than my original country.

I thought there might be other people like me on HN who travel a lot for work so I want to share my experience with Netflix's unfair charging policy. I live in Turkey but I travel a lot for business and seems like I've created my Netlix account with Standard plan when I was in Poland 2 years ago. Today I have just noticed that Standard plan is 27.99 Turkish Lira in Turkey but I've been charged...

I don't think using "the wrong letters" is illegal in the US. What I've meant was it is as wrong as claiming the usage of "the wrong letters" is illegal in the US.
Re:The letter Q was illegal in Turkey from 1928 until last month on Monday October 21, 2013 @06:23AM (#6584528)
The letter Q was never illegal in Turkey. It was just not allowed to be used in names of people/companies etc. due to the fact that it is not in Turkish alphabet.

It is like letters ç,ğ,ü being illegal in US.
