Because it's been remastered, essentially, from its original format and resolution. I'm sure that you could color "correct" it to a more modern state, but then you'd be the one doctoring it.
Hence "essentially", yep. It's been updated, whether by hand or by algorithm or both, and the finished result is a hybrid of old format & resolution and modern graphic standards.
I’d say it’s because they’re rich and lived in a mid century modern home, which is a fairly mainstream style today. MCM style is now being used in “cookie cutter” new construction. For example, the sconce looks like something I could buy at home depot. The home has very clean lines, is unadorned, and well manicured which are hallmarks of the style.
Also, the dad is dressed in a throwback 1920s style suit and hair. This contrast of “prohibition era” fashion and MCM design makes it more difficult to date. We see a lot of design mashups in today’s world, but it was less common in past decades, so that may be adding to the illusion imo.
For some reason his expression seems more modern to me. It’s like he’s a looking at the camera to tell us we’re probably wondering how he got here, but it’s so beyond the days of Ferris Bueller, which is itself decades beyond how this picture feels, that the subject doesn’t even need to say the line. They know we know they’re looking straight into the camera, that the 4th wall is dead. That feels postmodern to me and therefore contemporary.
@[email protected] With film cameras things tended to be more composed. You wouldn’t waste a shot when the kid was not posing. The further back you go, the more rare candid shots become. The kid not participating and dad smiling despite knowing the shot isn’t ready seem incongruous to the period.
