Resizing a processed image

Hello all. I have an archiving/workflow/pro​cessing question.

I always shoot raw to give me a true negative and more choices later. Now I will spend some time (sometimes a lot of time) processing my image to get it just right for print or web or whatever.

Now suppose sometime in the distant future I want to make a huge output from that image. Rather than upsampling the final processed tiff or jpeg, I would think it would be better to go back and upsample the original raw image and post process this at the new larger size. I'm just wondering if there is anyway to archive all the processing steps that I went through to get that great smaller version.

Now, I know some (perhaps many) of the amounts of contrast, satuation, levels, curves etc. will differ because I am working with different size/resolution ratio than the smaller version. I'm just wondering about the feasability of software or plugin that would document the exact steps in Pshop. Sort of like a processing EXIF file.

Just wondering...maybe too much so.

Pekka-seeing your photographic art makes me want to hear your musical art as well.

If you use Photoshop there is a notes tool. It shows a little sticky on the canvas. I think they are saved.
When I shoot astrophotos I open text file in same directory I am saving my images in, and then wirte stuff down in there like filtering, processing and the like.

If you do your work in adjustment layers, you could just transfer them over: open the new, larger file, then drag all the adjustment layers (curves, levels, Hue/Saturation, etc.) over to the larger file.

Localized retouching may need to be redone, though general 'dodging and burning' layers could be resampled with minimal impact.

Both are great ideas, thanks guys.
