I was a film (Kodachrome, Ektachrome, etc.) from the 1970s till full conversion to digital with a Canon 5D. Have spent a lot of time scanning film and processing with Photoshop and Topaz filters. Now that Topaz no longer support most of their filters as changes continue to occur with Apple Mac processors, Mac OS and Adobe products I have had to look for replacement tools. I am now a solid user of NIK tools, mostly Viveza3, Color Efex Pro5, Silver Efex. However, the (still working) Topaz filters Denoise AI and SharpenAI are still essential to my workflow.
