This might be a basic question, but why do raw files look different in different software when using to 'flat' settings (all settings to zero)?
LR and other programmes seem to produce very different results (very dull, low contrast etc.) when set to 'zeroed', compared to Canon's DPP software or a RAW viewer such as Irfanview.

Eventually, there is something one must accept ... there is no such thing as "all settings to zero".
- The image must be deconvoluted (means rgb-pixels have to be build from the bayer data). Differences
in the deconvolution formula used will produce differences in the resulting image.
- A gamma has to be applied. If you convert raw data without this, the image will never ever look
even anywhere near what you saw with your eye.
- A whitebalance value needs to be selected.
... Each program does it's own decisions, so the results are different.
... and for Irfanview ... it's default setting is to use the jpg-preview-image ...
you need to switch to the raw-data explicitely in the setup. This is at least a possible cause.
