Notes on History
At some point in our lives, we all wish we could go back in time and do things just a bit differently.
We'd like a do-over.
Well, as photographers we know we can stop time with our cameras, right? So, is it really a stretch to think we can use our great software, Photoshop, to actually go back in time?
In reality, the creators of Photoshop, in their infinite wisdom (how they actually created such a thing in the first place boggles my mind!) realized that occasionally, we might make a mistake, an errant keystroke perhaps. When this occurred we might be frustrated if we couldn't go back and "undo".
And so they gave us the power to go back in time. The almighty "UNDO". In fact, they not only gave us one UNDO, but through use of a built-in memory system called HISTORY, they let us have several whacks at UNDOing"
Alas, though they were generous to a (de) fault, sometimes we find that we just can't go back far enough, right?
But perhaps you have been imprisoned by your own thoughts?
You CAN change "HISTORY"!
You can change it from it's default of "20" to a much more reasonable number for us mortals, like between 50 and 100. (However, don't get carried away with your new-found power. If you get crazy and decide to set the history to 999, you'll pay the ultimate price. Photoshop will eat your every last gigabyte of memory trying to keep track of what you are doing. Ultimately, your system will slow to a snails pace. Just remember, the higher default you set, the more memory is consumed.)
So here's the simple HISTORY tip that will save you many hours of frustration and deleted layers:
Go to EDIT - PREFERENCES -PERFORMANCE
("PERFORMANCE" might be "GENERAL" on versions 7 and earlier)
Look for HISTORY STATES. Change the number from 20 to anywhere, say 50 -100, and click, "OK".
It's a really simple tip but one that's often overlooked.
Doing this can really make your time with Photoshop a much more pleasureable experience.
