As for the "average iso" the "average photojournalist" uses, I'd say old habits die hard. Any pj who shot film shot 400 speed B&W (Tri- X, TMAX) and then 400 speed color negative film (Ektapress, Fuji - I know, a few shot chromes), probably sets a digital camera to 400 under many conditions?I do. I got used to shooting 400 and still can make an almost exact exposure guess at that speed. One nice thing about digital is being able to change the ISO without changing rolls of film. So we shoot at 100 or 200 in good light, and bump it up as necessary. On the newest cameras, 400 looks better than 200 did a few years ago, and 1600, or 3200, is the new 400.
