Blur/Sharp tool

[AWysy]

Hi,
Just started to use GIMP.  I am making my first experiences.
I have one question concerning Blur/Sharpen tool.   After blurring and switching to sharpening the blurred part does not "return" to the original by applying the sharpen too.  However after the sharpening, blurring functions.  Is this normal, or some of the settings need to be changed.?
Thank you

No image will sharpen to its original state if it has been blurred alot with a sharpen tool.

If you want to return the image to it's original state in that same session just press undo as many times as you blurred it .Go to edit>undo convolve until you don't see undo convolve any more.


Or, there is a quicker way - Have your 'history dialog' on where it shows you all the steps you have taken and click on base image - Takes it right back to the original image. Same session
