Win 7 64, CS5 Cannot access "Load" button in Duotone Options. ( Under Image, Mode. ) No Load option is shown. All tutorials say to click on Load. Additional Plug-in folder is checked. under Preferences, Plug-Ins. Presets/Duotones/Pantone(R)Duotones/ selected. First time trying to use Duotones.
First uncheck the additional plugins, since that doesn't have anything to do with doutone presets.
(that's for plugins/filters that go under the Filter menu)
Your probably reading stuff that is referencing older versions of photoshop for the duotone dialog.
In photoshop cs5 you can get the load presets and also see a list of the already installed presets by clicking on the areas indicated in the screenshot below.
Thank You! Got it.
