I know very little about the ins and outs of image manipulation – I’ve stumbled my way around the Gimp’s interface once or twice but really with very little understanding of how things actually work: levels; filters; masks etc.

I usually just stick to good old GraphicConverter for resizing my images for the web. But, I’ve noticed that for some reason the smaller images often seem to look fuzzy and indistinct in the detail.

So this evening I was quite pleased to come across a simple technique to make scaled down images look better using a Photoshop function called “Unsharp Mask”. I don’t have Photoshop, but luckily it turns out that GraphicConverter has exactly this same function in the “Effects” menu.

So here’s a photo of a banana flower from our holiday.

As you can see, the first is scaled without any additional work, while the second has had the “unsharp mask” treatment.

I couldn’t begin to tell you how it works, but it does.
