DIY High Pass Filter (and my soul patch!)

[OK_to_Point]

I'm still stumbling after the second hurdle too. Using CS2 and I got as far as creating 2 new layers and applying the blur. Then what in Heaven's name is a "grain extract mode" and how do you do it? Could you list the steps a bit slower for the newbies? Thanks........appreciate your patience.....

It appears the Gimp has one over Photoshop here, there doesn't appear to be a 'grain extract' blending mode in Photoshop.

As I'm not sure what the expected results should look like, I'm not sure what to substitute it with...any ideas?

OK and zespri - Here's what a photo looks like, following wulf's tutorial, using The Gimp, just after converting the top layer to "grain extract." Hope this helps. Good luck. This is a great technique once you figure it out.

Thank you Chip, very kind of you! I'll try it out tonight

Thanks Wulf for the tips. Will try experimenting with this.

I just finished running Wulf's sharpening technique through Gimp. Real nice and simple to follow, even for a newbie like me.

I do have a question though. If I try to do it to a RAW image Gimp's raw editor opens up, so how can I open the RAW image in the full version of Gimp so I can get to all the tools?

Thanks

First process the RAW file. You can then work on the output image in the Gimp and save either as a JPEG or in a non-lossy format, like the native XCF. I find JPEG with only minimal compression works well for my needs.

Ok, so it has to be edited in another format other than RAW. I was hoping Gimp had the ability to open RAW files like CS4 does.

Also, have you found that editing the other components for example like color, brightness etc...in RAW affects the results of the sharpening technique after saving it to a supported format?

You can't edit and save in RAW, because then it wouldn't be RAW any more. Sharpening is always my final edit after all other alterations including any cropping and resizing to reach the final size. I tend to work just with JPEG images but by the time I get to sharpening RAW wouldn't be a factor anyway.

I wasn't thinking of saving in RAW but at least being able to open the RAW file, sharpen it then save to preferred format.

Thanks, much appreciated.
