P: Fujifilm X-trans cameras and halo around blue areas

Objects photographed against the sky or other blue coloured areas get a "halo" when images from Fujifilm X-trans cameras are developed in Lightroom.

My camera is a Fujifilm X-T1. Before this, I owned the X-E series cameras and noticed the same thing with them. Today I installed the latest version of Lightroom (5.4) and the problem is still there.

Lightroom doesn't handle blue coloured areas well. Take a look at the blue and red traffic signs. You may need to click the images to view them full size (they are 100 % crops).

Compare this with the same raw file developed in Capture One:

Looking at the red channel only shows this clearly

For comparison, the same image in Capture One

That's a good question. I used to use DNG but with Fuji I use RAF because I don't know what the converter does.

Does the improvement also apply to files converted to DNG on import, or only to original RAW processing? (Sorry if this is too simple a question, but I'm not sure what the conversion to DNG entails - is it via the ACR Converter, in which case the damage has already been done?

I also can confirm that 6.1 produces better results than 6.0. I have some old pictures I processed with Iridient trial and the 6.1 are much closer in quality than the 6.0 ones were. But there is still room for improvement.

Apparently not. At least the problem is still evident in the tram photo used in this DPR article: http://www.dpreview.com/articles/1887...

I have processed the same image in LR5.7 and LR6.1 and there's a significant improvement, here are some 100% crops. In each case the LR5.7 image comes first followed by the LR6.1 image. Processing was fairly normal, modest sharpening with detail at 100%. The first two shots are from near the centre of the image, the second two are from the corner. Shot with 18 - 135 at f8.

I wasn't able to find the same raw file. For the LR 6.1 conversion I used another raw file from the same day, shot with a smaller aperture, so the background is sharper/more contrasty.

What's important to me is the rendering of the blue/red areas of the traffic sign (you need to click the images to see them at 100 %). LR 6.1 is a clear improvement.

Also a huge difference in sharpness. Did you change any other settings between both versions, or is this the default rendering?

Yes, there is an obvious improvement. Compare the traffic sign above (LR 5.x) with this image from LR 6.1. Both are 100 % crops; you need to click the images to see them att full size.
