I have been trying to enlarge an image using Genuine Fractals. I changed Res. from 72 to 300, and dimensions of image down low enough to give me a File size of about 50mB ( my aim is to arrive at a jpeg file of >48mB ).I saved as a Sting file, this diplays in Explorer as a file of approx. 20mB in size?? Saving this as a jpeg takes the file size down to approx. 10mB.? How do I acheive my >48mB jpeg, when Genuine Fractals is telling me the file size is larger than it is ? Thanks,Jerry
