Well, 15 min walking to the Metro store was enough to cool my head off . OK. everything what I (and few others ) wrote, is just BS! It is irrelevant what parameters any given photo editor uses to open the raw file. Once you see the bitmap image, this is your starting point (base level) for any further modifications. You apply this and that modification, again it is irrelevant to know it (or save those numbers, like sharpening of 45). What counts is, how your modified bitmap image looks. If you are happy with what you see, just save it! Whether you save it as a TIFF or JPEG (except as a replacement of your original raw file), it doesn't matter. Whenever you open it again, and regardless on which editor/viewer you use, you will see again the same image.

Just back from the Metro myself.

Unfortunately it is more complicated than that.

These different softwares are starting with and processing the RAW data which has not been transformed into an RGB bitmap.  They are not further processing the "bitmap image" as you call it.  Any tweak you do changes the parameters to reprocess the data from RAW.  And when they do this, their de-mosaicing algorithms are different, their processing/enhancement alorithms are different, their colour mappings are different, etc.  It is not simply that one applies parameter x = 45 by default and the other 55.  I can get a result in LR that is impossible to get in DCU, and vice versa...

But yes, after I generate and save the result (in LR it is an explicit Export function) it is fixed and should* look the same in any viewer.

* of course this is not 100* true and can vary depending on how/if the viewing software uses the ICC colour profile embedded in the output JPEG/TIFF image.  Sigh.

So, I think that the entire discussion here was, well a good exercise with (our aging) brains .
