At one time,,size mattered...storage was at a premium and file size had to be small,,,jpeg was an ideal cure for a big problem,,,,I used photoshop before I used a digital camera and scanned to tiff because it is lossless,,"tagged image format" tif,,,getting the most out of your picture was important to restoration. yada yada yada,,jpegs are fast, easy to use but have an algorythm that runs in them that throws away data that makes the file sizes smaller,thus a lossy format.,,,,large jpegs or fine until you blow something way up,,,there will be artifacts that show up in the sky or skin as little blur spots....use what ever you like and be happy,,when the time comes to make the most out of your images you will want the most in a format ..
