Hi

I have (for example) an image (single) which I find easier to work with in Photomatix (the tone mapping helps short cut the layers needed for contrast control) but I don't get the nice features (of even my old version of) ACR which can help to fix chromatic aberration on my wide lens.

Is there a way that I can fix the aberrations in the processing flow?

thanks

You will have to process the RAW file first. Once converted to a TIF file in Photomatix your options in ACR are limited for processing TIF files.

Hi Don

ok ... that's what I thought. I have already tried that (didn't cost much ;-) and definately the Photomatix options on the TIFF were no as hot. I got close by
processing the RAW first to a jpg (set aside)
processing RAW in ACR
processing that tiff in Photomatix
taking that again into Photoshop and doing a match colour based on the jpg produced in step 1


got this:

which isn't quite as snappy as the RAW processed in Photomatix but at least it clears up the chromatic abb (which is exaggerated in the tone mapping)

thanks :-)

Nice shot! You can achieve the same look with a single file by processing in ACR and finishing up in PS using the Highlight/Shadow tool.
