Re: Monochrome Camera (conversion) vs Software Conversions?

When I use b&w film I rarely shoot "naked" (that is, sans filter).  :)  With a monochrom(e) camera it would likely be the same. Yet I often use an orange filter, which gives a visual result not far off what I'd get from a Monochrom without any filter. Hmmm…

Anyway photosite counts are at the point where you can sacrifice some spatial resolution during RAW conversion and get higher tonal res in return, and on an image-by-image basis. One RGBG photosite square equaling one output pixel or a similar scheme. It'd be nice if software creators took closer note of this (I say, for approx. the 100 millionth time since ~2003). [Edit begin]The point of this being: you could use the RGBG matrix for each output pixel as a set of filters for monochrome output. Way more flexible than a set of fixed-value filters screwed onto a lens mounted on a mono camera. In RAW conversion you could also skip the demosaic-to-RGB-color stage and go directly from Bayer data to (filtered) monochrome.[Edit end]

Sorry for the delay, folks. For my own purposes, I've concluded I prefer the greater control in post. Anyway....


1. A discussion about software vs hardware BW conversion does not make sense. All hardware solutions are in fact software based this way or another and all software is run on hardware. I used to design both.
Hardware = monochrome sensor = sensor without a colored array (Bayer, X-Trans etc)

Software = starting with a color image, and using tools in post to convert to B&W (LR, Silver Efex etc)

That should've been obvious from the post, where I was comparing sensor conversions and the Leica Monochrom to LR  ;)

2. RGB conversion has its advantages - flexibility in manipulation and many other ones. On the other hand Leica Monochrome gives such a beautiful rendering of details, especially in dark areas plus wonderful tonality incomparably better than my EOS 6D after any type of BW conversion I have tried.
Yes, I'm asking if the overall image quality of a monochrome sensor is superior enough to offset the loss of control in post.

I suppose I should have requested some side-by-side examples. ;)

I pity the poor OP Mousecop.  Ask a simple (but slightly ambiguous) question and the thread wanders far away.  Guillermo first tries to deny that its about hardware modification vs Monochrom and then writes a thesis about why it's a bad idea.  In such situations the OP is never heard from again.  I suspect that all he wanted was some first-hand experience, but I think he's out of luck in this forum.
Not really, I just made up my mind, and got distracted from the discussion by actually taking photos ;D
