Really ?
The couple PJs I know seem to use small sized JPGs for multiple reasons... speed of processing... plus if it's only going into newspapers or web pages... starting with RAW wouldn't even be noticeable.
PJ's I know only shoot raw.
I shoot raw, since I often do not have time to set spot on wb and need exposure latitude on location and under pressure. Starting with raw is
noticeable .
You know pj's who shoot small jpegs and do not think raw would make the difference. So, your point is ?
My point is... they don't whine about having to deal with 350 NEF sized files (as in your first post),
because they have a choice not to . Nor would anyone viewing their published PJ photos know if they shot RAW or not.
Nor do I believe it's a "common situation in reportage".
Unless you work for Life or Nat Geo... why is white balance an issue for your "reportage" snapshots.
