Even today's most beastly medium format cameras top out at 100 megapixels, and the size of their sensors pale in comparison to the behemoth footprint of an 8x10 film sheet. Check out this awesome video that examines just how much detail large format photography can provide.
Coming to you from Ben Horne, this fun video follows him as he closely examines a 709-megapixel drum scan of an 8x10 image. Large format photography (unlike medium format) is an entirely different beast (notice how he refers to his 150mm lens as his "wide-angle lens") that requires a different workflow and a lot of attention to technical parameters, but the payoff is huge negatives that provide an unbelievable amount of detail and a look that simply can't be replicated. As a result, Horne ends up with a digital file that's almost 30,000 pixels on the long side and weighs in at an astounding 4 GB for the TIFF file, but it appears the unwieldy size is worth it. If you're wondering, Horne mentions on his Instagram that he used Velvia 50 film for the shot. Velvia 50 is a beautiful choice for landscapes and probably the film I'd recommend if you want to try shooting landscapes on film.
