Incident light measurement

[Dave6223]

Today, I started thinking, well not much else to do at work today. And yes, I know it's dangerous. I have a Weston Euromaster, and I began wondering about Incident light metering. So, in order to try and calibrate it to the camera I took a reflected reading from grass with the Olympus, reasoning that grass was a suitable mid tone and adjusted my meter by adjusting the ASA reading until the EV on the meter tallied with the camera. I then started taking test shots using my invercone and the camera in manual mode. The results of the test shots were great! No burned out whites or unreadable dark spots. OK, i realise that today was overcast and it certainly wasn't "contrasty".

Anyway, this has really encouraged me, so here's the question. What would you estimate the exposure tolerance of digital as? I know that 100asa colour neg film had roughly + or minus 4 stops.

How much compensation would you estimate for a contrasty scene?

If I were to bracket 3 shots + and - 1/3 of a stop might that be reasonable?

Or do you not favour incident light measurement? Sorry it's been a bit of a long post, but I really am keen to learn.

I took this one of a marigold, using incident measurement, what do you think?
