"Last weekend I took a 360 deg panorama and on processing the files discovered two frames had the partial magenta coloring.
There does seem to be a problem with the green channel but with the tools I have I can't get my head around it. Looks like I will have to contact Canon."
This article may seem as if it's about a curious incident, like a musing. However, it actually has very practical ramifications and uses to a photographer. Raw data damage can be symptomatic of an underlying problem, and a glance at the raw data can give one the facts that one needs to inform a company that your camera body has problems that need fixing.
As we already mentioned in the previous article “Forcing a Raw Converter to Render Tones Accurately”, most raw converters apply some hidden adjustments to a raw shot, often resulting in a bumped mid-tone, clipped highlights, and compressed shadows. This is done to make the shot look good, but can also lead to all sorts of confusion.
Here, we intend to show you how to determine what sort of unseen exposure correction is being applied to your raw shots by your raw converter.
"What happens to my mid-tones? I set exposure using exposure meter; open the shot in Adobe Lr (or Adobe Camera Raw, or some other converter) - the shot looks overexposed and everything starting from mid-tone and up looks very flat. If I shoot RAW+JPEG, JPEG looks OK, while RAW is not. Should I expose lower?"
Please don't lower the exposure, you will be underexposing by more than 1 stop additionally to the underexposure due to camera meter calibration. Not a great idea, especially if the light is low and you are already above ISO 400.
Instead, change the default settings in your raw converter (read on for a suggestion) or adjust on a per image basis. Having customized defaults, however, will save you a lot of time down the road.
New setting Misc Options - Use small fonts in information panels Decreases the font size and shrinks the gaps between the informational panels in the upper part of the program window. Useful for the lower resolution displays.
