Thanks for the analysis and suggestions Troy.
I did try “Partial Metering” and ran into problems with light tones on butterflies and dark tones on native bees, so went back to “Evaluative”.
I am now using ACR in CS4 and use the “Recover” for highlights and provided not all 3 channels are blown, I can usually rescue some texture in the whites. I also find that Shadow/Highlight can be helpful too, although it would be nice to get it right in-camera.
The MR-14EX does have “built-in” diffusers as the two crescents are not clear – they have that opaque, ground glass look. However, I do find changing the over/under exposure setting on the MR-14EX a bit awkward;
- Take eye off subject
- Look at rear LCD panel on flash
- Press Sel
- Press + or –
But I think that I should be able to do the same from inside the Canon 40D view finder; that is, select flash exposure compensation – I’ll read the manual!
Cheers
