Hi Sean
Think Majoli does so because of camera choices and reasons for the choices though, rather than time constraints or printing...but do know what you mean.
LOL at the tyranny of choice...how true. I think it's why I sometimes shoot BW in jpg honestly, even knowing it's inferior in it's ability to be processed as well. You can't go back again, and it commits a person, like shooting film did. Yup once a person has a program like Photoshop, after you get the settings down, and write whatever action (or recipe in DPP)...it can be pretty well automated...for RAW or jpg.
I've written a bunch of BW actions in Photoshop that took me forever. Then after I got them all done, says to myself "why not?" and went out and bought some rolls of Tri-X for my old film stuff....then did what I always did....put them in a drawer and haven't got them developed yet
Back to the topic:
I've talked to a few pro's (one sports shooter in particular) he shoots in RAW and jpg at once, sends in the jpgs for review...gets back from the editor which are promising, then sends in the RAWs (this all saves much time). So although it's off subject, it may be applicable in certain ways in this case, find it interesting that even for someone who shoots exclusively RAW, that jpgs are useful in that regard. A person could also do that when shooting, to compare BW jpg vs Color RAW....since the jpg would come out in BW I think. I know it does in my Olympus when shot together. In that way a person could have the best of both...'in camera' and 'out of camera'
It would also give a person something to compare to and find out which look promising. My old clunker 10d doesn't do 'in camera' BW so not sure what the RAW-jpg possibilities are with the later Canons like the XTi. But my Oly will do both at the same time and can even be changed after the fact (bw-jpg, color-RAW), as will the10d(only not in BW and not afterwards) So a person could do both if they wanted, in a later Canon. Sometimes colors can translate much differently in BW and would give a faster preview (especially in certain editors or viewers), even if shot in RAW...and something to compare to after the temporary raw profile files are changed, if so later...say in Photoshop or DPP. (although they can be changed to camera default anyway)...just a thought. I might try it myself...albeit backwards for my 10d.
Thanks Sean...bookmarked that one for sure...great photographs and a link to a larger site.
