I received an email from NIK software today with a notification that all their Complete Collection of Plugins for Photoshop/Lightroom have been all upgraded to be compatible with 64 bit versions of Photoshop and Lightroom. This is great news if you are using a 64 bit OS but you were stuck using the 32 bit version of photoshop when you wanted to use your NIK Software plugins. NIK Software also recently released a new plugin for Photoshop/Lightroom called HDR Efex Pro. This plugin is now included in the complete collection package. If you bought the complete collection before HDR Efex Pro was released you are elligible for special discount pricing.
