Very good, i like the tabs! And i find the histogram is very useful

It shows the distribution of luminance in the image. In the example, it is showing that the vast majority of the image consists of pixels that are fairly dark.
To the left of the histogram is dark values, and to the right is light values.

hhmmm ok i understand but i dont see how this can help for image calibration....anyway i think may this visual represent may help somehow!

it'll show up if you're clipping your whites

Nice solution of the space issue with tabs!

The histogram is a nice addition but only in combination with the tonemapping settings, imho. All the other settings only affect the histogram slightly. Also the histogram can be made much, much smaller! I think 150 x 75 pixels or so should be enough to get all the information you need from the histogram.

I would suggest you place the histogram directly in the tonemapping tab. If it's that small it should fit nicely.

yup that window was just a quick test - it wasn't even displaying the correct luminosity - but having it on the tonemapping tab is a great idea.

this is cool... with auto-update enabled, the histogram updates as you move the sliders. It's cool to watch!

histogram should have width 256 px - 0-255, and would be VERY VERY nice to have RGB chanels

mrCarnivore · Post by **mrCarnivore** » Fri May 04, 2007 7:41 pm

Doesn't necessarily have to be 256 pix wide. The single values are not that important. The overall form is much more important.

Nice position for the hist. You should change to colour to black/white though!

I see no need for having a seperate histogram for each colour.

But if you did, you can use the corresponding colour for the hist colour. Then you could display them all at once with mixing the colours. Might lead to a very colourful information display that is totally unreadable, though.

we could have a set of radio buttons for the histogram type:

o Red
o Green
o Blue
o Luminosity ( = 0.33R + 0.56G + 0.11R)

changing the colour to white is an easy one (or, perhaps 50% grey

).

Other things that I'll show you lot soon include:
a couple of denoising filters, and the return of linear tonemapping.
