What is the flashing Highlights warning us of?

Any idea what the "highlights" review of a image is telling us?

The manual says its the brightest part of a image, but i suspect its a warning of overdriven (255 rgb) level - or ???

Pretty much :) When the highlights flash, it means they've been blown and no detail was captured for that area. Or as you put it, past white (ffffff+)

That's my limited understanding anyway :)

Hi Piro,
So you think theres no buffer? - that it means youve already blown highlights .
Bummer! - i cant tell as theres no specification of the way its calibrated in the manual.
Thoms guide probably has it ...

Yep, it's your (already) blown highlights.

The good news is that in many circumstances you can simply reshoot after modifying your exposure to compensate in some way.

In fact that's exactly how I set up for a new area. Take a test shot - check for blown highlights, adjust EV, test again recheck do similar with histogram to make sure it is reasonable then shoot away. If I'm expecting blown highlights I may recheck on specific images. This is my default view on the viewfinder. Makes for easy chimping :wink:

An even faster way to counter shots with visible and doubtful highlights, is to utilise the bracketing feature on the D70 et al - over - mtr - under is a good start :wink:
