p.1 #1 · remove lens vignetting with an other picture
Is there anyboby that knows how to remove the lens vignetting on the pictures?
I have tried with Photoshop CS3 in the Filter/Distorsion/Lens Correction
but this tool is not enough to remove my lens vignetting.
At this point I have taken a pictures for each lens aperture (lens is Leica R 19mmf2,8;the last before ROM) through an opal glass with the lens pointed
to the north sky. In this way I have a right picture of the vignetting.
I would like to know if there is a way in Photoshop to use these pictures like
a tool/filter to remove the vignetting.
At this address you could find an example: http://img387.imageshack.us/my.php?image=19mmf4nf1.jpg

I have never tried it, but you could apply the lens correction more than one time by using multiple layers if a single layer was not enough.
Another idea, on the image that you have captured of the vignetting ... you could use it to build a mask. Invert the mask. Then use curves on a separate layer with the mask to remove the vignetting.
There is component that allows you to remove vignetting and create a profile for your lense - in fact it may be available from a user.
It is an Open Source software and available free. You will enjoy learning it - it can do tons of stuff and it will keep you out of trouble for at least the winter lol
