So, now I can either going chasing down some list of past changes to find whether it was some past increase or decrease that contributed to the error, or I can simply move the slider from +8 to +6. And what you would see by simply looking at the slider on the tool in question is +8. Take a value - an increase of 5 followed by a decrease of 3 followed by an increase of 7 followed by a decrease of 1 makes an overall increase of 8. You might have made changes in a chronological sequence but the image wouldn’t change if you made those same changes in a different order. All the history list does is to visualise the undo/redo operations made with Cmd-Z and Cmd-Shift-Z and, as you should know from that, once you make a change after a few Cmd-Zs, there is no way for you to redo what used to be there. There is no way you can do anything to anything in the middle of the stack without losing everything else above it on the stack. Never forget, a history list is known in programming parlance as a LIFO (last in first out) stack.

If you weren’t right, revert to a new virtual copy and start playing again.

You don’t like the image as it stands now and going back in the history list will mean you will no longer know what the image looks like now whilst you are trying to figure out how to (or whether to) make an adjustment at that point in the history, knowing that you will lose countless changes made after that point.įar simpler to make a virtual copy, start playing with the tool that you thought caused the problem and see if you were right.

get to the point where you don’t like the present appearance of the imageĭo you go back to the contrast change or the ClearView Plus change? Whichever one you go back to, the version of the image you see when you get back there will no longer have any of the subsequent changes after that change, thus how do you know what will happen to the current image (with all changes) when you change that setting in the history list.

do something else that alters the contrast, like ClearView Plus.

change the contrast from 50 to 56 (a change of +6).

But if you did some more editing afterwards and then use tool A again you will get a complete different image If you use tool A for the first time you can switch it on/of to see the difference. But which one made the change that I now find myself wanting to revert?Īre those who support a history list really saying that you can remember where in that list to go back to - especially if there are many changes to one particular tool? And then, when you get back there and find the change they made was wrong, that you have to make the choice whether to change the setting and lose the last couple of hundred changes you made after it? Most times, I use the tone curve to adjust contrast and levels but, occasionally, I will use the selective tone sliders.

If I was experimenting with a particular slider, I would end up with a long list of little adjustments, which I have then got to try and remember whether I made the adjustments before or after something else that has a similar or contrary effect. Surely far simpler to make a virtual copy for where you are now, then you can enable/disable any of those tools as you see fit until you find which gives you the best results. If you adjust things based on what you see at the moment, why would you not simply adjust the tool itself, rather than risk disturbing so many other adjustments to so many other tools?Ī case in point is deciding whether you should be using ClearView Plus or one or more of the contrast adjustment tools.

But if you have made several (some plus, some minus) corrections, are you really telling me you can tell which of those corrections in the history caused the problem?Īnd, if the result of all the adjustments made to that particular tool comes out at -12, by how much are you going to adjust it when you find it in the history list? Bearing in mind that any experimentation will immediately wipe all other changes to all other tools used after it. Disabling a tool is disabling all the corrections made by that tool and that might be several. I decide for a correction based on what I see at that moment.
