If your photo is already being resized to 1000px, you are bypassing our unsharp mask which fixes the slight blurryness that occurs when photos are re-sized down.

Literally, its such a small amount of sharpening that you would only notice it if you saw the 'raw' resized version prior to unsharp masking.

What led us to applying this unsharp mask? One day we were comparing a photo Pete had uploaded to ePHOTOzine to his original photo and noticed that the one on the site seems blurry. So we investigated and noticed it only happened when photos were being resized. So we tried resizing in Photoshop and didn't get the same problem. We also compared our resizing quality to other sites and decided something needed to be done about it. So off we went, and a few days later we came up with a Photoshop quality resizing by introducing this unsharp mask.

So I guess the same applies for 600px ?

Yes, if you have already downsized it to 600px. If you upload a 1000px, we will resize and unsharp mask the 600px.

As I understand it, EPZ only apply sharpening to uploads that they downsize and as you downsize before uploading, I assume that they don't apply any sharpening to your shots and therefore I don't see how it affects your images.
It would be interesting if David would confirm this.
PS the comment wasn't mean't to be snide

thats correct. Only resized sizes have the unsharp mask applied.
