Chromatic Abberation Help

Hi guys,

I attended a wedding recently (not a wedding photographer but went along for the experience). I noticed that some of the shots I took suffered abberation. I wondered if anyone could help me with a raw file, and correct it as it's very obvious. The shot seems to have lost detail too but it's the only one I have of the bride and the wedding car. I have tried a Lightroom lens correction fix and it didn't help, so tried it in Photoshop and that didn't help either. I tried adding a mask to remove magenta/green and that also failed as I was removing skin colour at the same time! I hear you can re align the colour channels but wouldn't have a clue how to go about it.

Any help is greatly appreciated!
 
Thankyou Miko, I haven't converted it to Jpeg as yet. If you have Dropbox would that be easier to send it to you?

The file is just uploading in here, I have to pop out now so was just trying to upload it as quickly as I could.

On closer inspection I am unsure if anything can be done with this file or if it needs to be scrapped. Despite me focusing on the bride and groom they don't appear to be in focus and the car behind does. This combined with the abberation is not great :bonk:
 
Hiya,

Really sorry I didn't respond yesterday; I hadn't forgotten about you (!), I just didn't make it to the computer. I can't look at it now as I'm on my iPhone, but it sounds like maybe it's unsavable anyway as the focus is an issue too. Like you, I doubt there's much point worrying about the aberration if the focus is on the car. I'm sorry I don't have advice that will fix it all for you! Bet you got tons of other, wonderful, shots at the wedding anyway :)

The colour fringing can be more or less fixed on the tiff you posted, my method of choice for this is the hue sat palette (in photoshop proper) from the drop down options select cyan, then (zoomed in well) click on the magenta fringing and ajust the sliders to narrow the range of colour selected. Next lower the opacity untill the fringing more or less vanishes. You will have to use the history brush to put the lips back in etc, and finally paint in the grooms neck colour (new layer set to colour) where the fringing has left it black and white.
I am supprised by how bad the fringing is, thats not a cheap lens either.

Thankyou very much! It does appear the focus is on the car, despite me focusing on the bride. The other shots I have of the car I clipped the back end so I didn't really want to use those, unless I form a composite I suppose! Thanks ever so much for taking the time to reply :thumbs:

Thankyou ever so much for those pointers, I will see if I can follow your method. I don't know if I have done something similar when I duplicated the layer and added a hue/sat adjustment. I then reduced the saturation of the magenta and tried to paint it in the areas that needed correcting, only as they are close to the skin it seems to be affecting the edge of the skin also.

I have no idea how I got this fringing as it has never happened on this lens before. I had it on a crop sensor body though as my full frame had the 70-200 f4L and I didn't want to be switching lenses frequently so I just took the husbands camera along to speed things up. I have used the 50mm 1.4 (Sigma) on that crop body before and never experienced it until this wedding so I have no idea how it happened!
