All I have to say about BMP is that I have never once heard a serious photographer speak about using it anywhere in their workflow. I've never heard of a graphics company asking for it when reproducing work. I am sure it has its uses and advantages, there's got to be a reason why it's a standard that the photography community at large has completely avoided. TIFF, JPEG and GIF are the only standard formats discussed. Again, there has to be a reason BMP is not in there. But if you're happy with it, go with it. I suspect you'll always need to convert to one of the above formats to share your images anyway, and god forbid you find a piece of software you want to use down the road because conversion will be time consuming.
And I have to say that it's absolutely ridiculous to think that people are buying software to post process their images because they just happen to be poor photographers trying to salvage something. That's pretty freaking ignorant.
