Filter Availability

[Alex Kotler]

Greetings-

On occasion, when working with (what is presumably) a rasterized image, the Artistic/Brush Strokes/Stylize/Texture filters are not available.

Why is this, and how can I activate them?

Many thanks,

Alex

make sure you're in rgb 8 bit mode.

Are you in RGB Mode?

[Alex Kotler]

why can't those filters be applied in cmyk?

Someone like Chris Cox would be more qualified toanswer this one, but I
imagine it would have a lot to do with CMYK, having an extra color
channel, using 25% more resources to apply the filters as well as the
difference between processing additive and subtractive colors.. would
add quite a bit of overhead, and the functionality would not likely be
used by any professionals. The general advice is to create, edit and do
all of yur work in RGB mode, and convert to CMYK as the final step.

"because".

Alex, I'm jumping in here late, but actually you CAN use these filters on an image in CMYK mode. Using you channels palette, if you select just one of the channels, you will see that the filters are available again. You can run the filter on each channel sepatately, then select the composite CMYK channel and you will see the results.

Awesome... I did not know that.. well never tried. My workflow
generally leaves my images as RGB until they are finalized, flattened
and the mode is changed to CMYK.

Thanks viol8ion

I work mostly in RGB as well. I just happened to read about this technique a few days ago on the NAPP web site (I think.)

I use it all the time and it works great, you can even add different filters to each channel for some really strange but cool effects (try crosshatching 2 channels and dry brushing 2 channels)
