Where to find the lens-profiles?

[ivars]

Where do I find the lensprofiles, in order to add my lenses?

[teknisyan]

Aftershot already has a lens database you can find that by going to DETAIL tab on the right side of Aftershot then click LENS CORRECTION, you'll see there the DATABASE tab. But if your lenses are lenses are not yet in the lens correction database, then you can go to the Manual tab.

More info on the Lens Correction and Detail tab at http://product.corel.com/help/AfterShot ... tools.html

I'm sure active Bibble and AfterShot beta-user will have a much better suggestion that this one.

One quick question...is there a way to create your own lens correction profile?

Yes,
get Hugin.
It comes with a nice tool to create your own lens correction data.

When you select a lens profile make sure you check the 'Enable correction' box otherwise nothing will happen.

I found it when searching (!) for profile_nikonSLR, but it cannot be edited using Notepad (like in Bibble). I must use Wordpad instead.

Is there a manual for using Hugin this way?

Is this a good way:

I've never tried it but there's a howto in the Bibble forums http://support.bibblelabs.com/forums/vi ... 94&t=15277 that might help.

No, that is outdated ;-(
Use the calibrate_lens_gui tool instead. MUCH easier.

You just need an image with decent straight lines in it.
(Which is actually much harder to get then I thought, don't have some many newfangled glass covered buildings here...)

the best hint i found about straight lines: create your own.

use a rope and stretch it over a contrasty background .. e.g. a white rope on your green lawn.
dont use a thin line.. you want this to be a bold line.

contrast and boldness!

and: weird as it is hugin has better chances to find straight lines with smaller image sizes,
so if you have problems try to set the "maximum image size" to something lower than the default 1600.

I have used lensfun (http://lensfun.berlios.de/). In (my) Linux the configuration files get installed at /usr/share/lensfun/.
