CornerFix 1.3.0.3 available for download

CornerFix 1.3.0.3 is now available.

 

This version enhances CornerFix's ability to correct for lens/camera combinations that exhibit extreme forms of optical de-centering and/or asymmetry, leading to "red edges". Broadly speaking, V1.3.0.3 is V1.3.0.2 on steroids as regards its ability to deal with asymmetry. :D

 

A note on compatibility: The new version will still load profiles from previous versions of CornerFix, right back to the first CornerFix ever released. However, in order to get the benefits of the new algorithm, you must regenerate your profiles using the new version. Using a previous profile on the new version of CornerFix will work fine, but will have exactly the same result as previous versions of CornerFix.

 

The new version can be downloaded here: CornerFix | Get CornerFix at SourceForge.net

 

Enjoy

Just to show the result I'm attaching the file used to make the profile and the same file corrected with the profile.

I use the CV 15 a lot, and noticed your post. Amazing, and the Vignetting is gone as well as the Magenta.

Can you let me know how you arrived at such a great remedy.

 

I just received a new M9, and the right side of the image is quite Magenta in many shots.

Nothing special.

The latest version of CornerFix did it. With the previous version I could manage to build reasonably good profiles for other lenses but never fort my CV15.

As always I have used an house made diffuser, overexpoising +2, bidirectional correction enabled.

Sandy did something special with CornerFix 1.3.0.3.

Cheers,

I have used Cornerfix 1.3.0.5 to create a lens/camera profile for my CV15 which has effectively eliminated the magenta fringe and corrected the vignetting..

 

The profile was created by photographing a white card with + 2 stops exposure from meter reading but checking the histogram to be sure there is no question of over exposure ("burnt highlight"). I checked that the illumination on the card was even with a spot meter.

 

There is a slight difference between profiles for F4 and F16. For practical purposes a profile made with an aperture of F8 seems sufficient.

 

Thanks to Sandy

I think max. aperture that makes sense for such focal is anyway 5.6 or 8. Doesn't it?

 

Could someone advice how to make this photo for calibration equally lit in home environment? Distance to card, wall must be short - du to wide angle. Then I have difficulties with this equal lit. Flash is not suggested I read.
