The degree of sharpening can be adjusted in Irfan, although Photoshop allows much more control and better sharpening alternatives, such as sharpening the luminosity layer, sharpening selective areas of an image, fading the degree of sharpening, and so on.
A good technique when sharpening with Irfan is to set the degree of sharpening to a low amount, like 5%, and then sharpen more than once until you've gotten to the point where you like the result. If you over sharpen a bit you can step back with the undo command.
