I've been using GIMP to process my photos for the challenges, and I have a question. Following the advice received here at DPC, I work with my photos in a "lossless" format (psd) until I'm ready to "save for web" as they say. After cropping down to 640 pixels it's time to save the file as a jpeg. I know to use the highest quality possible while still staying under the file size limit. But one of the options offered upon saving is "smoothing." I have been keeping my "smoothing" at zero up until now, because I didn't know what it was.

Playing with it as a test, it seems to soften the photos and decrease sharpness when I crank up the smoothing.

Do you smooth? Do you advocate smoothing?

Any thoughts on this provocative Friday night topic most welcome.

I could be totally wrong, but it sounds like the effect is something like Neat Image?
If that's the case - be careful, be VERY careful!!!

The plastic skins don't do very well for the most part.

smoothing is exactly what it's name suggest. It smooths out transitions between original pixels. Smoothing is best used in upsizing, though. So, no, I wouldn't use it for down-sizing to 640.And don't forget to sharpen (USM) after resize.

BTW, you mention you keep the photo as a PSD til you save a final. Im Gimp, I think you'd be better off using its native file instead of the psd.

What's native for GIMP?

(And thanks for your help!)

.XCF files are what you should be using (native format).

And I think you'd be better off using Neat Image if you want soft/smooth images. More control that way. I would recommend NOT using smoothing, though I don't have much experience with it.
