M240 Under Attack

Profile the camera & it all goes away.

 

Flatter looking files are from increased dynamic range so now you have more to work with.

 

In ACR or LR, turn on out of gamut indicators and move black point to just where it turns on, then do the same with highlight.

 

Only in dire emergency do I use auto WB. Set it with Whi Bal Card or Expo Disk . Between profile and WB properly set, the camera is perfect

Profile the camera & it all goes away.

 

Forgive my stupidity or inability to find posts about this - but how does one profile a Leica M240 in Lightroom?

 

What settings is a recommended profile to start with? Normally I just do it by eye - I have a 7D but I don't use profiles, I the adjustments I use is very little time to time, lest my camera was thrown in its metering.

While the latter is obviously true, the choice of CCD vs. CMOS has no bearing on either spectral sensitivity or IR filtering.

 

I think there is an element of misunderstanding creeping in here.

 

The native spectral sensitivities of CMOS and CCD sensors are not necessarily, but are likely to be, different depending on a host of factors relating to their manufacturer. Your note would seem to imply that they are inherently the same, which I'm sure is not true.

 

It has to be borne in mind that very small changes can - emphasise can - significantly effect the rendition of colours; particularly things like flesh tones. That is one reason why film manufacturers produced many different professional colour negative films.

 

A sensor manufacturer has to take into account the native sensitivity in designing the Bayer filter. Again the reason why film manufacturers produced special films for use with specific filter for colour separation work.

 

The IR filtration is in addition to the Bayer filter and again surprisingly small differences in the filter's absorption curve can have a profound effect on the "colour rendering" of a sensor.

 

The problem is that once the sensor has generated the RGB data there is nothing the subsequent digital processing can do to change these aspects of colour rendition although it can, of course, change many other things.
