On many occasion, I have been to conferences and on training where the presenter has done a demonstration and used a screen magnifying utility to enlarge part of the display. There are many utilities available that provide this functionality and are typically included with the accessibility option of most operating systems.
Having asked many a presenter what they were using to magnify the screen, most pointed in the direction the Sysinternals utility ZoomIt which I have since used. More increasingly I am presenting and doing demonstrations on my Mac which leaves without such as useful utility.
After a short time reviewing various Apps available, I decided on Zoom It for Mac for a small price of £0.69 in the Mac App store. It sits nicely in the toolbar, and allows you to customise the loupe size, zoom and shape through various key shortcuts or from the toolbar menu.
Enhance your demonstrations and use a utility like either of the magnifying utilities I’ve mentioned – I sure am!
