What plug-in host you are using and what version it is (e.g. Photoshop
Elements 6, CS 3, etc.).
Steps to reproduce your problem.
In 32-bit bit depth mode, there is banding in the proxy preview. This banding
will not show up in the rendered/processed image. The banding when previewing
in 32-bit mode happens due to a limitation in Photoshop with third-party
Adobe Photoshop CS3, CS4 or CS5*
*CS5 must be opened in 32-bit mode for the filters to work. 64-bit CS5 is NOT supported.
CS6 is NOT supported.
OS X 10.4.0 or higher
PowerPC or Intel processor (the plug-in is a Universal binary that works
on both platforms)
Adobe Photoshop CS or higher (e.g. CS6), Photoshop CC, Elements 2 or higher,
Irfanview, or Paint Shop Pro X2
A 64-bit version for Photoshop CS4 is included.
Windows XP, Vista, 7 or higher
Intel or AMD processor that supports SSE2 instructions (Pentium 4 or higher,
AMD64 or higher)
Photoshop CC: Adobe may install both a 32-bit and 64-version of Photoshop CC. Copy the filters into the respective folders. Make sure that you are running your desired version (32/64) of Photoshop CC.
