Why old Black & White films and TV seem to have better picture resolution than stuff filmed in the 80s and 90s?
In: 179
On top of the film vs video tape argument, b&w tv also had better apparent resolution than colour because of Chroma Subsampling.
I’m going to use pixels to explain, although technically analog tv didn’t really use pixels, but it’s easier to visualise.
Pixels on the screen are measured in brightness (luma) and colour(chroma).
The problem is when you have hundreds of thousands or millions of pixels that requires a lot of information and analog tv didn’t have the bandwidth to accommodate.
To get around this they compress the colour information by using the same colour for a group of pixels instead of individually. They still have their brightness info so there will be different shades of the same colour.
The result works quite well, but it can make the colours and overall picture look muddied.
