coconutdaydream Posted March 31, 2005 Share Posted March 31, 2005 the only way we could save CA is if we prevented an earthquake from the san andreas fault! it would split it in two! Link to comment Share on other sites More sharing options...
basscheffers Posted March 31, 2005 Share Posted March 31, 2005 Not sure such software exists. If it goes in like shit, it comes out like shit. The only real way to avoid it is to get a decent lens. Link to comment Share on other sites More sharing options...
miha_steinb_cher Posted March 31, 2005 Share Posted March 31, 2005 I can't agree with previous two posters. CA can be quite reasonably fixed. Take a look at: http://www.caldwellphotographic.com/TutorialsDistortionAndColorFringing.html The piece of software in question is free an extremely powerful, unfortunately it isn't user friendly. Best regards, Miha Link to comment Share on other sites More sharing options...
vatovec Posted March 31, 2005 Share Posted March 31, 2005 If You shoot RAW You can do some in Adobe`s Camera RAW. Link to comment Share on other sites More sharing options...
steve_bastiman Posted March 31, 2005 Share Posted March 31, 2005 Have a look at Harycover's Fringing Action Author: Mohammed Yahyaoui on http://www.atncentral.com/download.htm. This action helps to remove color fringing in high contrast shots. Link to comment Share on other sites More sharing options...
timarmes Posted March 31, 2005 Share Posted March 31, 2005 The radial correction method described in the link above has been turned into a nice plug-in for photoshop that comes with profiles for numerous camera/lens combinations. It's call PTLens, and it's free. http://epaperpress.com/ptlens/ Another free program, based upon PTLens (and using the same profiles)but this time written as a standalone application, is called RadCor. RadCor meets your demands more than PTLens in that it also has the ability to remove chromatic abberation using a nicer UI than the PanoTools solution. http://super5.arcl.ed.ac.uk/baspmirror/radcor.html Finally, PictureWindow Pro as a similar feature.

gene_brewer1 Posted March 31, 2005 Share Posted March 31, 2005 Ok, I have to ask and I'll probably be sorry I did. What is CA referring to other than California? Gene Link to comment Share on other sites More sharing options...
skainet Posted March 31, 2005 Author Share Posted March 31, 2005 Hi, Gene,CA means Chromatic Aberation aka purple fringing.And many thanks for all corresponders! Link to comment Share on other sites More sharing options...
crabseye Posted March 31, 2005 Share Posted March 31, 2005 I'm hoping they're talking about Chromatic Aberration. Link to comment Share on other sites More sharing options...
john_houghton Posted April 1, 2005 Share Posted April 1, 2005 CA is chromatic aberration, which is generally understood to refer to a lens defect of colour fringes caused by the effects of refraction varying with the colour of the light. These are predictable, to a degree, and can be corrected by software. OTOH, Purple fringes at the edges of regions of high intensity probably have their origins in the image sensor and cannot be so readily corrected. I haven't seen any authoritative explanation for the precise cause of this defect. Link to comment Share on other sites More sharing options...
