With the new EVF's appearing on the market, specially thanks to mirrorless cameras that have no OVF, I wanted to start a discussion of how your favourite EVF view would be for the advanced user. This is also applicable to LCD's Live View.
For advanced user I mean a RAW shooter who wants to have the capture process under total control, not caring to obtain a finished image in the camera. Surely camera makers will insist on JPEG related information since most users are not so demanding about the RAW capture, but it can be interesting to share points of view.
Here is my proposal V1.0:
- Exposure parameters: shutter, aperture and ISO.
- B&W image display: to make other information more easily visible (colour is secondary since WB will be adjusted in the RAW development). The display exposure (brightness) of the image could be either normalised regardless the exposure parameters chosen, or be correlated with the actual exposure parameters chosen. I.e. it could always appear well visible, or dark/blown according to selected exposure parameters.
- RAW histogram (http://www.luminous-landscape.com/forum/index.php?topic=33267) in EV divisions: the histogram displayed corresponds strictly to RAW data (the camera would approximate the RAW data that would be obtained with the selected exposure parameters based on its real time sampling of the scene), and it is displayed in EV divisions. Changing exposure parameters would shift the histogram but would not affect its shape. Just by counting how many vertical divisions contain information, we know the scene's DR.
- RAW clipping warning: areas saturated in some RAW channel would blink red (or any combination of colours allowing to find out which precise combination of channels saturated), areas with such a low exposure that falls out of the sensor's DR (e.g. SNR=12dB criteria) would blink blue (or again any combination of colours allowing to find out which precise combination of channels saturated).
- Focus Peaking (http://www.luminous-landscape.com/forum/index.php?topic=56246.0): yellow tinted.

Any suggestions? what do you miss? what would you add/change?

Hi,
In my view a blinking highlight is most effective. We want essentially to ETTR so we want to have an exposure where specular highlights are overexposed but normal highlights just within ETTR. The histogram doesn't actually tell what is clipped. Shadow clipping is in my view less useful, with the DR we now have. Focus mask is a bright idea, but I have no clue how effective it is.
I really want to be able to enable each feature, so I can have my own combinations. For instance I want histogram and virtual horizon at the same time.
Best regards
Erik
