I installed a twain driver (i now realize this was a mistake) in my CS5 for the purpose of scanning within it. Since doing so, I can no longer apply my topaz filters (or any 3rd party filters for that matter). The filter interface opens fine, and i can see the filter on my image, however, when I click out of it, nothing is applied to my image. Help?!?
I've got snow leopard. I'm not very technical. I did research uninstalling the driver, however, havn't found anything yet. Do you know how I would go about doing so?
Not a Mac user myself, but there are many here who can help out.
For a very quick fix, try removing the Adobe TWAIN plug-in or at least disabling it by closing Photoshop and typing a ~ (that's a tilde ~) in front of its name, then relaunch Photoshop.
That's why Adobe doesn't even include the now-optional TWAIN plug-in as part of the default installation of Photoshop any more.
