I often want to make my workflow revisable - I often go back to an early step and change it, and, often with help of Smart Object if later layers are NOT all adjusting layer, I could pass that change to later layers, thus add least extra workload.
Now I need help with a specific situation: say I pack the following steps into an Action: copy a channel, High Pass, Apply Image 3 times boosting contrast. All in a Smart Object, so workflow is revisable.
After this Action ran, I go back and change High Pass value, now: I want those 3 Apply Image changed correspondingly and automatically, question is: how can I achieve this?
I know I could replace 3 Apply Image steps with one curve, but sometimes it's subtle, and this question is also about method, I could use this method, if any, to other situations.
