How to use Adobe Photoshop CS5 to remove Chromatic Aberration in HDR photos

Here is a quick tutorial on how to remove the nasty red / green hue on edges aka Chromatic Aberration that often occurs in HDR photos. I’m going to use the last photo I posted since it suffered from some extreme Chromatic Aberration issues. I know there are some automated tools in Lightroom to adjust Chromatic Aberration but I haven’t had good luck with it on HDR images. It seems to me that Adobe didn’t build that tool with extreme HDR cases in mind rather it seems to work well for normal photos but falls way short for HDRs. The process below using Hue / Saturation layer in Adobe Photoshop is actually quick and easy i.e. it typically only takes me 5min to complete the process.

Note – this is an intermediate / advanced level tutorial. If you need basic Photoshop training like how to create layer masks, use the brush tool, etc, I highly recommend checking out

This is the image opened in Photoshop after I completed the HDR process. As you can see, it has some nasty red / green hue around the edges inside the image.

The first step is to create a Hue / Saturation layer in Photoshop.

Next, grab the saturation slider and move it all the way to the left so the entire image will be desaturated.

Ok. Now for the fun! Invert the Hue / Saturation layer mask with ‘Cmd+I’ on the MAC. This will revert the image back to its original view. Select the brush tool. Make sure to select color to ‘white’. Then use brush tool to ‘paint’ over all of the areas with red / green hue which essentially desaturates everything you paint.

Once all of the hue issues are resolved, slide the ‘main’ saturation slider back to zero.

Now select the ‘reds’ from the drop down and move the saturation all the way to the left. This removes all of the red saturation in the areas we ‘painted’ with the brush tool without messing with the other colors in those areas.

Note the ‘reds’ didn’t remove all of the hue issues so next I went to the ‘magenta’s’ and repeated same process.

Finally, I repeated the same process with the ‘greens’.

As you can see the final result is much improved! Hope you found this quick tip useful.

Thanks for visiting!
