Great Resizing Technique in Photoshop

[James Fee]

Why? I want my photos to be resized so that the longest dimension is 800 pixels (or some other size — but I use 800 at PBase)."</i><br /><br />Tommy Williams posted a technique by Jeff Schewe which he recommended downsizing with Bicubic Sharper in 66% increments to get close, then use the File->Automate->Fit Image... option to complete the result. Tommy has posted the results using both the one step and this two step method. Interesting....

Single-step example with USM applied. Spot the differences.

Maybe since I don't use Photoshop, I don't understand the significance of this. I use Corel PhotoPaint and its "Resample" function. Then I select the desired size in pixels. By default, the aspect ratio is locked so that if I set a 1280x1024 picture to be 800 pixels wide, the finished product is 800x600 with no distortion.

Not bad. The unsharp mask really pulls out the detail of the ground.

Yea, IIRC, Bicubic Sharper does a little sharpening. In any case SI is used mainly for upsizing, not downsizing of images. Even then I'm still rather sceptical of it's supposed benefits.

Agreed. The differnces looks marginal,
