And guess what? NO post-processing AT ALL was possible with slide film (which also happened to have a very narrow dynamic range...).
So, for SOME at least (me included), there is pleasure in sticking to straight-out-of-camera JPEGs, and being forced to THINK more before tripping the shutter to make sure one gets everything right (exposure, white balance, dynamic range settings, etc.) in camera.
...which finally brings us to my choice of camera gear:
Fujifilm produce some relatively compact and very sturdy "mirrorless" camera bodies with direct 'old school' controls and a range of high-quality fixed focal length ("prime") lenses (as well as an electronically-coupled adapter for M-mount lenses). Thanks to many decades of experience in producing photographic film, they also know a thing or two about how to achieve gorgeous colour and tone.
The following minimalist 'kit' allows me to photograph the way I like to, and get very pleasing out-of-camera JPEGs, without having to resort to the crutch of post processing in order to "fix" defects such as colour, tone, chromatic aberration, flare, etc.

C1 "Soft" Film Simulation = NS Low-contrast / low-saturation colour negative film simulation; useful for interior shots.
C2 "Portrait" Film Simulation = NH, Shadow tone -1 Medium-contrast / medium-saturation colour negative film simulation; especially suited to portraiture.
C3 "Fujichrome" Film Simulation = S Medium-contrast / medium-saturation slide film simulation; a good all-rounder for outdoor photography.
C4 "Nelson" Film Simulation = CC, Highlight Tone = +1, Color = -3, Grain effect = Weak High-contrast / low-saturation slightly grainy slide film simulation; reminiscent of Jimmy Nelson's style.
C5 "McCurry" Film Simulation = V, Grain effect = Strong High-contrast / high-saturation grainy slide film simulation; reminiscent of Steve McCurry´s style.
C6 "B&W Portrait" Film Simulation = AG Medium-contrast black & white negative film simulation with green filter; especially suited to portraiture.
C7 "Moriyama" Film Simulation = BR, Shadow Tone = +4, Highlight Tone = +2, Grain effect = Strong Very high-contrast, grainy black & white film simulation with red filter; reminiscent of Daido Moriyama´s style.
