I just bought a used 645Z and love it, and while the shadow recovery is incredible, I am finding it noticeably easier to blow highlights than on my other cameras and am finding myself adjusting exposure compensation downward severely.
A few questions:
1. Are you actually blowing highlights or are you looking at the histogram in your raw converter to make the call?
2. Can you recover all the captured highlight information with the exception of specular highlights?
3. Assuming you are shooting raw which editor are you using?
Quote: Given that the camera is known for its dynamic range I am a bit surprised at how easy it is to blow highlights that can't be recovered in Lightroom. Are most people finding this to be the case, and any tips for how to deal with this except dialing down exposure compensation?
I guess that this answers the second question but maybe you could expand a bit on how bad. Or ideally post an example or if ok send a pm for a link to a raw image that demonstrates this.
Quote: I understand that Live View reads the histogram from the raw sensor data so that gives a more accurate view of blown highlights, but I usually prefer using the viewfinder, especially when not using a tripod.
I am not at all sure that Live VIew can read the data from raw and build a histogram although technically possible I do not think Pentax implemented this (Neither did Nikon - just a rumour). Well at least that is the opinion I had when I looked at the histogram in LV vs the histogram shown in play - they appeared to be the same.
If you are using the histogram view of a captured image you are looking at a JPEG representation and therefore a 'correctly exposed' JPEG is an underexposed raw. So you should be able to judge how much extra headroom you have when jpg histo, starts to hit the wall.
