Magenta & green colours in highlight areas after raw development

[16thEarl]

G'day,

 

I have a Fujifilm X-T2, which is my first X-Trans camera – so this question might just reflect my lack of experience…

 

I took a photo of the ocean, using the standard camera settings with an compressed raw and JPEG image written to the camera's memory card. A small version of the JPEG image is shown here:

If I develop the compressed raw file into a JPEG using software outside the camera, there seem to be magenta and green colours in the white highlight areas of the waves. In comparison, the in-camera JPEG image shows just white highlights.

 

I've included a cropped section of my ocean photo here to show the difference:

 

 

I tried using both Silkypix DS Pro 7, Affinity Photo and Iridient Developer (all for Mac). In each case I tried to use the default/standard settings in the program. The results were similar with the colours. I wanted to try DCRaw, but it didn't seem to handle compressed-raw (RAF) files at all.

 

I'm not sure what software I should be using, and whether to suggest that Fujifilm should be releasing their in-camera raw-to-JPEG conversion software as stand-alone software that could be used outside of the camera.

 

Can anyone suggest what's going on here?

 

Thanks,

 

Warwick

Just after posting this message, I received a call from Fujifilm support, who were very helpful, and said that it's just chromatic aberration, which is corrected automatically in the JPEG image produced by the camera, but not in the external software I was using.

 

I had wondered about chromatic aberration, but hadn't noticed it being quite so obvious in my photos before, so I thought there might have been something else going on.

 

It still leaves me a bit unsure about what's the best raw development software to use. I've downloaded demos of everything I can get my hands on, and will have to do some more testing!

Many of the raw developers and editing software out there should have a function to remove CA, as they're quite common. Lightroom does an excellent job, just to name one. But if you searched which editing suites could handle it, I'm sure you'd find a decent list.

 

Best of luck!
