When you create a layout, we have to keep in mind it's digital. Paper scrapbooking always has the paper there to re-arrange or change whenever desired. But with digital, we can't change it after if it's only saved as a jpeg. So when I save a digital scrapbooking page, I save it 3 times!
1. Save the layered version of the layout! Save using TIFF
format to save spaced AND to see a preview of the layout in your
folder! For a refresher on saving in TIFF format, see this blog post tutorial.
Save the jpeg version of the layout at 12x12. Make sure you choose a
quality level of at least 10. Even if you plan to print it on 8x8, make
it 12x12 and re-size in the program's software.
3. Save as a 600x600
jpeg for gallery posting. To keep it distinguished, I add "gallery" at
the end of the file name. Also, I keep my gallery-sized layouts in a
separate file from the TIFF and full-sized jpegs of my layouts.
important to stay organized with your designs! Make sure you take some
time to sort layouts by year (and month possibly too!)
