I know rules aren't for thumbs but in general:

The larger the print the more sharpening in USM?

A 16x24 would need a little more sharpening than a 12x16?

Or am I on the wrong track?

The principle is that resampling reduces sharpness. More up-rezzing = less sharpness, so yes, more sharpening would be needed.

Thanks, Elie. As I suspected.

I'd like to know as well, how do we tell how much sharpening is required for different print sizes?
Is there a visual method of checking thru an LCD monitor? Or is it by trial and error?

Most of the time im making 4R prints and my experience has been that on LR3 the default sharpening value of 25 seems to work just nice on my 1D mark IIN's images.

However if I do print larger I'm unsure how much sharpening to use.


5D Mark II | 5Dc |17-40 | 24-105 | 70-200 F2.8 IS | Sigma 50mm 1.4 | 580EX

Since you have LR3, the simplest thing is to trust the Output Sharpening. It is interactive with the resizing function, self-adjusting to give the amount and type of sharpening appropriate to the resize. It is actually an automatic version of Pixelgenius' Photo Kit Sharpener built into LR and works very well.

For those who sharpen in another application a sort of 'inexact but close' guide is to view the resized version at 50% zoom and sharpen until it looks slightly too much. This is because inkjet inks spread slightly, reducing sharpness. For lab prints (photo-laser) just make it look good at 50%.
