Wow… for the first time in my life, knowing intricate information about film development colouring paid off

It's tricky. I got one that was full bright standard colour... from 1912. Normal contrast and hue and saturation, no noise. I assume recoloured later?

There are bw photos from 70s and colour photos from 50s. Contrast and noise and hue can give clues, but nothing stops a photographer from using old film in new times. I ended up going for cars and styles more when possible.

I'd love to see trends and stats on the photos across regions and collaboratively filtered (e.g., someone who accurately predicts photo XX is more likely to accurately predict photo YY).

Also, it's a super curious dataset, photos with year metadata.

Fair point! Maybe I just got lucky and my 5 or so photos were all time accurate to their development methods!

Simple and fun game. I just wish the score was more forgiving the older the photo was. It’s a lot harder to tell 1905 and 1910 apart than 2015 and 2020, from the perspective of 2023.

I love this. The summary at the end could be a bit more compact. Scrolling all the way to the bottom to start a new page is a bit inconvenient.

Maybe full points for scoring within 5 years? Some photos are very hard to place in an exact year.

This is a fun little game. It is interesting to see what the tells are for the time periods. The reliable ones for me so far are military uniforms, cars, and computers. Hairstyles and clothes for some time periods are a give away, but some of those have thrown me off too.
