hi there, i've been reading the 'blending' article because i want to learn how to combine 2 shots, so i can increase dynamic range in my shots.
it says when bracketing for the two shots, they should be about 2-3 stops apart.
if i want to go for 2 stops, what should i set the bracket too? should it be 2.0?
on my D70 it looks like this:
+2F 2.0
hope that makes sense...cheers.

Put the camera on maual take a reading off the sky, take a reading of somethere dark make an exposure on those two values
Its digital its free - take 10 shots - play - do what ever you want

The 2F means it will take two shots. The 2.0 means it will expose with a 2 stop difference.
I normally set bracketing to +3F 0.7 or +3F 1.0 or +5F 0.7 depending on the scene.
So with +3F 0.7 you get one normal exposure for which you metered (0 EV) then one underexposure (-0.7 EV) and last one over exposed (+0.7). You can then blend those together by putting them on top of each other and masking out the part of each exposure that you don't want.
Set manual exposure, manual focus, manual white balance for consistant files.
Have fun.

0.7 or 1.0 f-stop bracketing for blending purposes sounds too little. Digital sensors have a dynamic range of between 6 and 9 stops - depending on who you listen to and how you calculate it -, so 1-stop bracketing is unlikely to give a meaningful increase in the dynamic range.
I bracket 2 stops over and under, sometimes 3 stops, depending on how dynamic the scene itself is. The 4-6 stop difference gives enough data to blend even a scene with deep shadows and bright highlights.

i've had many cases it was helpful to lift the shadows just a bit, and make sure the highlights don't get blown, by bracketing 1 stop. so...

... i of course totally agree, it depends on the scene.
take care

Use the histogram to decide - if you have shots which hold both shadow and highlight detail thoroughly, I don't think there's much point taking shots below/above these!
