sharpening
 

Love your magazine. Can’t wait to read and watch it monthly.
The question I have is on sharpening. I understand how you want it at 1/1 when you are sharpening, but what resolution. Lets say you have a 600ppi image, and you are printing at 300ppi. Should you convert it to print scale first? Should you adjust the scale you are viewing. What I mean is with the example should you view it at 2image/1screen pixel. If you say your sharpening is good at 1.0 pixel radii should you multiply it by image/screen. I use Lightroom for sharpening, I assume the same concept is for sharpening in Photoshop.
I assume that it is best to leave it at the highest resolution as long as posible durring editing.

Thanks for any comments or insight.

Hi Robert, welcome to the forums

I'm not sure how much of a difference this would really make. However. if you downsample the image before sharpening you're more likely to introduce sharpening artefacts. The greater the resolution of the image the more latitutde you have for sharpening before you start to oversharpen.

Personally I wouldn't downsample and then sharpen unless I really had to. You've got less pixel data to sharpen and so to get the same sharpening effect you're going to have to sharpen more (I think :confused:)!

As a Lightroom user you may find this article worth reading. It's in 2 parts - the link to the second being given towards the bottom of the article. I've personally found it very interesting and in fact have bookmarked it hence being able to direct you to it. :)
