If I add noise to a very simple image, then save and close that image, is there a way to view how much noise I've added to the image when I reopen it? Can I then delete it at that point?

The only thing you can do with a filter once you apply it is change the fade (opacity and/or mode) or use history to remove it completely. Once the image is closed the filter is set.

yes, but first you have to make a layer then aply the filter:noise if you want to remove it just delete the layer(the layer must be in screen)

You can't apply noise to an empty layer. You can duplicate your layer and apply the noise to the duplicated layer. That way you can delete or hide the duplicate if you don't want to see it.

you can create a New Fill or Adjustment Layer (click the little "half black/half white" circle icon at the bottom of the Layers Palette) and fill your layer with white, add noise and change the blend mode to "softlight" (or the blend mode that gives you the effect you want ;))

this way (like dreamer101's method) you can discard the layer if it doesn't work out.

as for seeing any setting after closing the file... no can do (for pretty much ALL things)!

one method you can try is to start recording an "action" and experiment. you can always add to it or pause it and modify or delete any steps that give "crappy" results. then if you save the action, you can open it later and examine what steps you took to get the effect you created.

just an idea...

Seeing how much noise you used last time is possible (but maybe that depends on your preferences), if you re-open the noise filter the last setting applied is still there. But a lot of times I write some of the visual recepies down.

Its all strange solution, i think. the best way to return to some state is to not change originals, edit copies. (open orig, ctrl+shift+s to save as.)

heres also nice trick for noice. Create new layer. Fill with 50 perc. gray. apply noise. set layer blending to overlay. you can create noise wery strong, and then reduce its effect by changing layer opacity.

Never change originals. That goes for people too, by the way.
