Using the Histogram - RGB or luminosity

I'm continuing my learning process with my GX10 & whilst I've always used the histogram in "standard" view, which I assume is the luminosity channel I've never really used the "RGB" option.

Obviously the RGB provides even more detail of the image - how many users utilise the RGB ?

thanks

I do, whenever I think there is a chance of blowing out a color channel. [images taken in incandescent light, bright flowers in sun shine, etc]

agree with rickster, anytime i'm inside, or shooting intensely lit reds. honestly, the first photo i take in any situation i usually have in RGB at this point (thanks to the help of people on this forum)... I often find myself keeping it in RGB and using the back wheel to zoom in if i want to see more detail in the image. But using the RGB histogram is a must!

I suppose it's all about the interpretation of the histogram reading too - whilst it may show some loss of one of the colour channels this is perhaps preferable sometimes to underexposing the rest of the shot, obviously depends on the "scene" been captured

I have recently set my camera to show the histogram first and am learning it...It turns out that this is a must as it tells me allot about the photo I just took.. Even more than what I see on the cameras screen...I have also noticed that when in Lightroom, I can adjust the histogram and again it is amazing..

If anyone has tips, I would love to read them. Sorry don't mean to hijack this thread, but I have not read much on histograms.
