RAW and Preview is Different in Exposure (ISO the same)

[Alexey Milokost]

Hi everyone,
Just noticed when toggling between RAW and Preview modes the exposure changes. The ISO is the same. It's noticeable when you look at zebra. I set mine between 85 ire to 95 ire. In RAW the exposure slightly increases. I'm on latest beta build. Is there a setting somewhere which I missed?
Thanks! Alex

There have been a few threads regarding this topic. IRE is not an exposure tool, it is a video output level tool. That is, it is an indication of the cooked (or processed) data level given the current meta data. Changing any meta data (including going into raw preview) will affect the IRE levels.

If you are concerned with actual exposure use:
- goal posts
- traffic lights
- "exposure" false color mode
- raw mode (then histograms, IRE, etc can be more useful)
