Cropping then sharpening or Sharpening before croppung?

[henrik_jacobsen]

<p>I scan my negatives (24x36 mm) at 2400 PPI. When I crop the pictures I have set the Width to 15 cm and height to 10 cm and the resolution to 274.4 pixels/inch which gives the final picture of 1080 Pix. in height and 1620 pix. in width. That should be enough to print 10x15 cm and exactly match the specification on a TV in HD quality (Full HD is 1080x1920 pixels in 16:9 ratio)<br>

Which order is the best - first cropping then sharpening or first sharpening then cropping?<br>

<p>I always sharpen for the final output size - always. </p>

<p>If I have an image that's going on the web and also being printed at 8x10 (or whatever) each output file is sharpened individually and as the last step of the process.</p>

<p>What Richard said. Sharpening depends first and foremost on output size (an image for the web will have different settings for sharpening than if that image is being printed). Of course it also depends on the content of the image, but that's a secondary (but still important) consideration.</p>

<p>One note: sharpening often will enhance highlights, so I will frequently use the Highlights/Shadows tool as the very last step to be sure that I have the right amount of highlights after sharpening.</p>

<p>OK. Thanks for the response. I did some tests and found that cropping/resizing before sharpening (both normal sharpening and Unsharp mask with 140; 3.5; 10) gives the best results.<br>
