What’s Coming Up Next? – Tom Bluewater Introducing RezRex for Mac OS X

Mac OS X software RezRex

TOKYO (MacHouse) – When you use a picture that you have downloaded from the Internet, you never know what kind of resolutions you deal with. As you know, the default set of resolutions for Mac OS X is 72 ppi x 72 ppi. But we are surrounded by cheap computers running Windows OS where the default set of resolutions are 96 dpi x 96 dpi. Besides, there are a lot of digital cameras supporting high resolutions like 300 dpi x 300 dpi. So if you are not careful with image resolutions, you can put yourself in big trouble.
