Re: FFT filter implementation problems

Ro,

Thank you for responding so quickly.

I did as you suggested doing an FFT and then immediately doing the IFFT, It worked just fine.

I then decided to again go step by step thru the tutorial -- This time it all worked great; just as your tutorial indicated.

I have no idea what I was doing wrong before.

Thank you so much

SteveD

Well there is a lot of interest in this tutorial , I am trying it as well. I am stuck on step 5, the spots will not change, wonder what I am doing wrong. I am new to using photoshop but you just click on brush and make sure black is selected and then brush over the marks with it right? NEB

Neb, let's try a few things....

- Are you seeing something like the image in step 4 - a grey noisy background with a few white stars?
- Did you leave on ONLY the Red channel in the Channel Palette?
- Is the opacity of the brush high (not 0, at least)?
- Do you have a selection active?
- Is the blending of the brush set to normal?
- If this doesn't help, then you could open another (Non-FFT) image and see if you can paint on that. Then, at least, you'll know if the problem is in the brush or the image.

Any luck now?

can't install fft

hi

this looks like a great trick - I want to try it.
have followed your instructions on down;oading the fft and winrar, tried to extract relevant files to filters folder, but nothing is showing up in my filters drop down list.

photoshop help says it might be in imports or exports, but I don't see it there either. Do I need to restart?

I am working on photoshop 7 on pc. Is that a problem?

thanks for your time.

"Plugins" folder

Close PhotoShop!

Quote:
Copy files *.8bf from bin folder to "Plugins" folder. Such as :

"C:\Program Files\Adobe\Photoshop 7.0\Plug-Ins".

Open PhotoShop.

It's now in Filter>Fourier Transform.

Hi, scsi,

If by "new version" you mean the April 2005 verison of the Alex Chirakov filter, then this is the one used in the tutorial.
The "old" version coded the FFT information into Hue / Saturation / Brightness and needed the RGB->HSB filter before and after the star painting.

If, however there is another "new version" please post us a link.

All the best,

Hi Ro,
thank you for the info. I just want to get certain that I didn't something wrong. I used this filter the very first time two days ago along with yor real great tutorial. It seems that I did everything ok, but I had to duplicate the luminance layer twice to get a stronger effect. After that i had to go with some tweaking with curves due to the misti look of the final image. But now it looks ok for me...

Fft

Thanks for the tutorial, and making me aware that this existed!!
I've spent hours getting texture out.
Flora may not remember but we corresponded on it's removal 3+ yrs. ago.
:-( I run on Mac so can't play with this.

You reference commercial products. What are they?

I'm using a mac as well and have googled all over looking for a plugin. So far no luck.

I have borrowed my brothers PC laptop and installed the filters, I tried the FFT RGB and imeadiatly did the IFFT RGB but the image came out transparent. Any suggestions?

OK, something weird going on. I tried it on a photo taken from a newspaper that was scanned in RGB mode and it worked flawlessly. I have been working on another photo that was scanned in greyscale, which I changed in Photoshop to RGB mode and after I finished painting the stars turned the channels on and doing the IFFT RGB the photo is transparent.

The file I’m working on that is giving me greif is here. http://www.rootschat.com/forum/index...;id=7099;image
