Unsharp Mask options Most tutorials, etc. advise finishing an image edit and saving, and then doing 'UM' on the saved image right b/4 printing, and leaving the image file alone, w/o the UM applied. Since I've discovered that applying just the right amt of UM to many images is desirable and has to be fiddled with making repeated corrections/adjustments, when I find that pleasant UM point I'd like to apply it and save that image, so I lock in that UM on that image and don't have to store/write down/remember the setting each time I open file to print. Is saving UM'd image an inferior method, if so why? Why not just save the UM and then open and NOT do UM for printing(since it was saved with UM)?

In case you do anything to it later. Resizing...

In case you want to do something with your file other than leave it as is, like resizing, photoshop stuff, etc... You don't want to be stuck with the sharpening saved in the file.

yep sharpening is the last thing you do. What if you wanted to enlarge the image? Sharpening beforehand could result in crazy noise. like I said, sharpening is the last thing you do

Yes, that I understand as you never want to edit further after UM is applied. I leave the original as is. I'm talking about a 'to print certain size w/UM applied' edit and a 'save as' e.g., 'DSC.....UM8X12' or such. Is it technically inferior or incorrect to save w/UM applied for some reason or other? I dislike keeping a log of printing info with UM settings, after finding the pleasing settings of radius, strength and clipping. So unless someone knows that UM is not as effective after being saved or is some type of editing function that cannot or should not be saved, I will soon start as it will be a substantial timesaver. Or am I alone in thinking UM is one of the most powerful tools in PSP or Photoshop and careful use can be the difference between an excellent print and one that is a step beyond that, jumps off the page' I think it's called?

"Yes, that I understand as you never want to edit further after UM is applied. I leave the original as is." Then you have nothing to worry about.

Stephen, any photo that you may want to rework should be saved as a layered tiff or psd file. If you are shooting raw, you will really need two sharpening layers since raw images have none to start with. First, start with your original image and do a moderate amount of sharpening on a new layer. Label the layer "presharpening" or something that makes sense to you. This initial sharpening will give you a better sense of your highlights as you go through other edits. The second sharpening is output sharpening that is highly dependent on the size of your image, your printer and the paper you are using. Bigger images/higher resolution printers/matte paper generally can handle more sharpening than smaller/lower resolution/glossy pictures. Do this sharpening last on a separate layer after any resizing. Label the layer something that tells you what you have sharpened for such as "USM 8X10 Glossy." Save the file with a similar descriptive name such as "Name8X10Glossy." If you later want to produce a 4X5, reopen the file and delete the output sharpening layer, resize and add a new sharpening layer with an appropriate description on the layer such as "USM 4X5 Luster" and save the photo as a new file "Name4X5Luster."
