So what is going on?

• Look at the Histogram in this software.

• It shows the ‘white’ pixel histogram as per the previous software but now shows the brightness level for the RGB channels.

• This shows that the red pixels are saturated at 255 and this is why there is a loss of detail in the ‘bright’ reds.

• How is this avoided?

• Use the old technique of bracketing your exposure where you have doubts.
• OR
• Buy an expensive camera which displays the RGB Histogram!
