Editing colour balance

[SimonCrutchley]

I’m interested to find if there is a way to manipulate the individual bands within an image in the same way that you can do in Photoshop etc; specifically, I’d like to be able to push the red band and reduce the green so as to be able to emphasise changes occurring in primarily green fields. I know that there are more complex ways of manipulating imagery (e.g. NDVI), but sometimes the simple methods can be very useful. I’ve looked at various elements within Pro e.g. Raster functions etc, but I can’t see anything similar. Am I missing something?

Thanks

If you just want to change how it's displayed in Pro, there's a little chart button next to the "Stretch type" drop-down in the symbology pane. This gets you rudimentary levels adjustment, like this example where I turn the world into a cool nightmare zone:

I think you can use "Export as raster function template" from the symbology hamburger menu to get something you can use in further processing, but this is where I hit my limit on raster processing so I'll let someone else answer the tough stuff.

Hi David,

Thanks for that. Unfortunately, my screen doesn't look like yours ☹️.

Do I need to do something else? Sorry if I'm being dense.

My data is RGB satellite imagery which is why our histograms have such different distributions. In either case you can change the stretch type, edit the min & max values to present, and you can drag the little arrows at the bottom of each color band graph left & right: this is what shifts and compresses your colors. This is all real-time so try to manipulate all the different controls and options on that pane and see how that affects your map.

Hi David,

My data is also satellite (4 band) , but I can't seem to get it to appear anything like yours 😞
