CA correction methods

Have noticed some CA on my most recent shots, and although its not very noticable on full-frame A4 prints, i'm not sure of the best/easiest way of removing it {which may be needed on crops}.

My only 'tools' are NikonView, and PS7, and don't plan on making expensive software purchases.

To be fair, i haven't used this lens {nikon 400mm/3.5} in enough variety of lighting conditions yet, to make a judgement of its CA qualities, and as i have spent my life with lens's that have suffered from this problem under certain conditions, i am not overly concerned {especially if i can slightly rectify it post-capture}.

On my recent Fulmar shots {high contrast conditions} there is no sign of CA on any of my frames, so possibly my woodpecker project was just one of those occasional situations where it has reared its head

Any tips appreciated {especially if they are suitable for a simpleton }

Hi Alan,
Do you have nikon capture NX? This has a chromatic abberation removal option, it's also a fantastic program for converting your raw files. NX has U-point technology enabling selective alterations without having to use layers, which is terrfic, you can download a 30 day free trial from nikon euro website, go on give it a go. Another option is to get a D300 or D3 as they have it in camera.
What's this simpleton stuff? Don't believe it at all.

Cheers Tim,

No, i don't have NX, and didn't realise there was a free trial available!

I shall give it a try {especially as it won't cost me anything }, and if it does the job, it will be worthwhile investing in the full version {cheaper than a new body into the bargain }.

Difficult to know whether the lens is the main culprit, or the tc, or the body {or all three}, or just a particular situation, so if NX does the trick, that will polish off my workflow a treat!

Thanks for that

Alan

Hi Alan,

I have just started using NX Capture since it came free with my D300 and have to say it it quite impressive! Check the link out below (you can downlad the trial from there):

Further Alan here's a link to some tutorials including chromatic aberration control:

PS I think nikon and sigma owe me a few bob.

Thanks both,

Just had a quick nose, and it looks very promising!!

Shall have a proper look after work, and will likely bite the bullet and buy the full program, and be done with it!

Thanks again

Alan

Doesn't look that bad to me at that magnification.
