fisheye

[dpipkens]

I just bought a fisheye lense and wondered if there are any "effects" or "filters" that work like DxO to bring out the curvature of the pic..or like fisheyehemi

Hmmm, have you tried "Lens" in the distortion effects? May need to play with the settings to get the look you want.

dpipkens,

You could try this freeware program:

GML-Undistorter

To correct for fisheye it needs a few passes at focal length settings of

around 1 - 4. It seems to prefer .jpg filetype.

There's a noticeable loss of sharpness.

Actually, Lens is now built in to Paint.Net, so there is no need to download anything - unless you want all those awesome extra effects!

I'm thinking you want to know how to apply that lens effect to get a real mock fish eye distort.

there is this method from back in Dec 21 2008 by Zizoiz viewtopic.php?p=235951#p235951

about the 3rd post down.

You will want the lens plugin. Search for it under plugins, if you don't have it.

Open your picture, and select the line tool. with the line tool, draw from the top left corner to the bottom right corner on you image. While you are doing this, keep an eye on the left side of the status bar on the bottom of your window. This will tell you how ong your line is. Memorize or write this length down.

Press control-Z, to undo the line you just made. You don't want it in the middle of your picture.

go to Image>canvas size, or press control-shift-R. Set the image dimensions to the value you wrote down, for both height and width. Set the little image icon to the center of its grid.

Use the lens effect to get the amount of fisheye you want.

go back to Image>canvas size, and reset to your image's original dimensions.

Hope this helps.
