K20D In-Camera Histogram Question

When using digital preview to observe the histogram prior to actually capturing the image, the histogram will look like I expect it to be.

After capturing the image, while reviewing it for 3 seconds (set in the menu), the histogram midtones usually do not extend as high up the histogram chart as they did during the digital preview. The highlights and lowlights pretty much remain where they were in the digital preview.

I'm shooting in RAW, but this is for information only........I don't see (or maybe not understand) where RAW would matter for this question.

I do not recall seeing this happen with the K100D or K200D.

Anyone else observe this with their K20D?

Thanks for any light you can shed on this.

Remember that what you see as a final product on the LCD when shooting RAW is the embedded jpeg. It would need a much faster processor to be able to convert/show a RAW file and meet peoples' expectations of timely LCD readouts. From what I understand, your jpeg settings are used to display the image, even if shooting RAW so this could be where the discrepancy arises.

I understand what you're saying. However (you knew that was coming), both the digital preview (and histogram), and image (and histogram) on the LCD after the shot is taken and written to the SD card are both from JPGs.



So again, if the histograms (digital preview and final recorded image) are both from JPGs, why would they differ enough to be noticed by me?

I just don't get it.

Just a guess but possibly the jpeg settings are not applied to the digital preview but they are to the image jpeg?

This same subject was worked back and forth "over there". The most logical answer came from a fellow named Phil Zucker. Easy to understand and makes sense to me.
