Well, 24 or 48 bits means how much extra colour your scan will have. Here's sort of what I'm talking about When you use 48 bit, you get MORE gradient colours to work with.

So your scan looks more smoother, more colourful, and more detailed. So, if you're saving your scans as JPEGs, you cannot use 48 bit. You are only limited to 24 bit. No matter what software you're using, no mater how much you try, you can't save your JPEGs at 48 bit.

When it comes to printing, you NEED more than 24 bit. Digital is limited. But analog is NOT. Printers can use 48 bit colours to make your photobooks.

Your Answer

So, if you printed a 24 bit scan, you'd lose out on all the extra colour gradients. Remember, printers can go 48 bit. This means your photobooks will have more colours gradients Now you know that JPEGs are only 24 bit. And printers can go 48 bit. So what you'll have to do is save your scans as 48 bit TIFF images. That way when you print your scans, your printer will be using all 48 bits of colours Most people don't scan using 48 bit TIFF because the files sizes are too big.

And now you know why you can't see a difference So a 48 bit scan looks like a 24 bit scan.

What you're doing here is taking that 4x6 photo and turning it into a 8x12 digital photo. The good news is, now you can take that 8x12 digital image, and print it at 8x If you took your 4x6 digital image and tried to print at 8x12, your image would look stretched and pixelated. Same with DPI.

But if you use say DPI, you'll triple the size. You'll turn that 2x3 photo into a 6x9 digital image. Then you can take that 6x9 digital image and make a re-print without losing any quality.

Step 1: Theory and Materials

A 4x6 photo scanned at DPI will be a 4x6 digital photo. If you want to double the size, you have to double the DPI. So, a 4x6 photo scanned at DPI will now be a 8x12 digital photo. And so on. If you're making photobooks bigger than 8x12, use DPI.
