I am a fan of film, but only shoot digital for convenience and cost. For Hollywood productions with big budgets, there are some unique elements of film which cannot be reproduced trivially with digital.
With film photography, there are two decisions right out of the gate that will have a major influence on the final look of your photos: film stock and exposure. So, Richard Photo Lab is breaking down the most popular types of film stocks we see at the lab and showing multiple exposure settings...

Film is very INSENSITIVE to over exposure because the chemical reactions have “burnt out” where digital is sensitive to clipping highlights but handles low light very well because it’s more linear.
In stills, when shooting the bride/groom at a wedding, you overexpose on film, knowing that the dress detail won’t be lost allowing you to capture detail from the groom’s black tux/suit. With digital, you are cautious to avoid overexposing to capture the dress appropriately and then need to boost the shadows, relying on the low noise of the sensor to maintain detail.
Here’s the problem. For stills, you can control exposure dynamically with ISO, aperture and shutter speed.
For movies, what happens if you have a continuous shot? You cannot change ISO trivially. For movies, you don’t have full freedom over your shutter speed since it dramatically changes the *look* of the film (think action scenes in Gladiator versus the non action scenes). If you were shooting digital, you now need an ND filter to let you keep the slow shutter speeds, but this may crush your blacks into loss of detail.
Of course, it’s important to note that after recording on film, it’s later scanned and processed digitally. There are differences in that as well which are not fully trivial to correct digitally, again due to the non linearity.
