I noted that in the PhotoJoseph Webinar on using the clone tool he was able to increase the zoom percentage to 1600% on the Mac version of Photolab 3. The Windows version will only zoom to 400% I would like the zoom percent in Windows increased to match the zoom of the Mac version.
There are two places right off the top of my head. First, when applying a local adjustment in a tight area, and second when applying a repair or clone of a area right up against, or passing through, another areas you don’t want affected. Higher magnification allows you to apply local adjustment masks and repair masks more precisely. I use both tools extensively and have found myself using them more and more as my experience increases. There are very few images to which I don’t apply local adjustments. On many occasions I’ve had to redo both LA’s and repairs because of the inability to zoom farther in to achieve greater accuracy.
