ACR Chrom. Abberation vs. 'Lens Correction' CA
Using P'shop CS2, has anyone else noticed that using the 'Lens
Correction' red/cyan fringe correction is much less effective (not able to achieve the same level of fringe reduction) than correcting CA 'on the way in' with ACR? Does anyone know why this would be the case? W |

ACR Chrom. Abberation vs. 'Lens Correction' CA
Not really a matter of opinion from what I have seen. ACR operation on
RAW files allows strong suppresion of CA (at least with 20D shots with an EF 24mm f/2.8 lens) whereas when I used the 'Lens Correction' it did not do nearly as well. |

Does anyone know why this would be the case? Not sure wether it applies here, but ACR does many of its corrections at Demosaicing time, or at Gamma 1.0 to selected colorspace conversion time. That may introduce differences with applying those corrections at e.g. Gamma 1/2.2 space. Bart |
