I could use a mouse to paint effects OR I can – and do – use a pen and tablet instead: more targeted, better control over the end results intended.
What I’d like to suggest here is that you guys set up the parameter controls for making adjustments to your filters so that we can make the Amount field pertaining to an adjustment active AND THEN be able to use the ‘up’/‘down’ keys to dial in a more controlled, more subtle adjustment.
I find this REALLY HELPS when I’m adjusting layer opacity in PS; making subtle changes with all the various settings I engage with in Lightroom as well.
Just as with those two Adobe clients, I find Optics can at times make substantial changes with just a bit of a move of my mouse; and, as I follow your screencasts it seems that your plugins (like both PS and LR) will often have a bit of a lag rendering changes made “in real time”. (It’s just the nature of all we’re asking the computer to do while we can’t see what’s going on under the hood.)
When making adjustments I will often keep a field active, make a few clicks up or down and then pause to see the changes rendered. Then, using ‘history’ I can move back-and-forth to see which adjustment level I prefer.
Would making the ‘parameter’ fields respond to up and down arrows or + and – become a tweak you guys can implement for our work here in Optics?
