The process to increase size in Genuine Fractals is very similar to Lightroom’s, and if you have the plug-in you probably already know how to do this.
Hopefully this gave you a bit more understanding of DPI and resolution when it comes to printing or publishing to the web. When using Lightroom, you don’t have to sweat the details and resizing in Photoshop is not too different. Just make sure to choose the right settings for your use and Lightroom will take care of you.
Just remember 72 DPI for web, 300 DPI for print, and 360 DPI for printing to an Epson printer. Now go make some prints and don’t let anyone tell you 150 DPI is good enough for an 11×14, it might be fine from a few feet away, but you know someone is going to look close and ask why the picture looks like crap.
