Classic rounded shape of loupe, dark semi-transparent overlay and 100% zoom for best visual effect. Use mouse scroll to change size of loupe or hold 'z' on keyboard and scroll to change the zoom.

This example shows loupe with some custom settings. Almost every aspect of look and feel can be changed. Here custom image overlay is applied, shape, size, snap, min/max size are changed also. You can easily allow/forbid size/zoom changing to end user. Zoom in is disabled, but use mouse scroll to change size of loupe.

Here we can see squared shape in action. Shadow and lens glossy effect can easily be removed using plugin settings. Use mouse scroll to change size of loupe or hold 'z' on keyboard and scroll to change the zoom.

Once again classic rounded loupe but this time without image overlay and optional shadow. Use mouse scroll to change size of loupe or hold 'z' on keyboard and scroll to change the zoom.

This time we specify other image which has to be rendered inside loupe. Basically it's the same image as source but with one difference - it's not a greyscale image. Using different images as thumb and target is very easy to setup and can create stunning effects. No resize & zoom allowed - scroll event ignore and handled by browser - scrolls page.

The same story here - two images one normal and second altered for a nice effect. Use mouse scroll to change size of loupe or hold 'z' on keyboard and scroll to change zoom factor.
