Best Resolution When Scanning Photos
Dec 13, · If you already have a physical photo but want to scan a copy of it for reprinting purposes, you will only need to scan it at a relatively standard DPI. This will allow you to reprint the photo at the size of the original picture. If your goal is to print a larger picture you will want a higher resolution. Picking the right resolution depends on what you want to do with your scans. To be safe, you can scan all your photos at DPI. This will give you an exact copy of your original photo. And at DPI you can view your digital photo on your HDTV at excellent quality. If you're scanning more than DPI you're just scanning the surface of your photo.
If you don't understand photo scan resolution and DPI, you're going to end spending hours scanning low quality digital images.
At 72 DPI, the digital images looked amazing on my computer monitor. I was shocked to see how bad the scans looked. Follow along, and I'll show you what's the best photo scan resolution is, so you don't waste time getting low quality scans. Take a look at an actual photo. If you look close enough, you'll see a bunch of coloured dots. Every inch of your photo is filled with of these dots.
Remember when you had those photos developed? The photo lab's printers could only physically print coloured dots to make up your photo's image. Of course, there were better printers that could squeeze more DPI. But most photo labs used DPI to print your photo. And DPI is good enough.
But what happens if you use DPI? Or DPI? I thought my scanner is going to get down into the photo, and uncover some extra detail. Remember, your photo lab used only DPI. When you use DPI to scan that photo, you're not adding more detail. At DPI, you have all the detail possible. Say you scanned your photos at DPI. They will look amazing on your monitor, and even when you display them on a 8' x 8' projection screen.
But say you took that DPI photo scan, and wanted to make a bigger print, here's what will happen This is when scanning your photos at a higher DPI is useful. Like I said, more DPI doesn't mean more detail. You see, when you use, say DPI, what your scanner does is it takes your photo and makes it twice as big. It didn't add any more detail. That depends on what you want to do with your digital images. Here's a few ideas and options for you Now it's time to act.

3 Actions Steps To Help You Decide What's The Best Resolution For Your Photo Scanning Needs If you use DPI, you'll be safe. You'll get HDTV quality images. And you can re-print them out at the original size. But if you want to double or triple the size of your original photo, use - DPI. If you plan to use your image in a print document such as a newsletter, you should scan your image at dpi or higher, but note that you will get a much larger file at these high resolutions. A good practice is to scan your pictures at the highest resolution you can, then use an image editing application to save a copy at a lower resolution. Pictures are printed at DPI by default. If we use a little bit of math, mixed in with a fun lego analogy, that means a 4x6 photo would be dots by dots. Scanners also measure their scans in DPI. When an image is scanned, dots are translated into pixels, which is how you end up with a x pixel image when you scan a 4x6 photo.
Picking the right resolution depends on what you want to do with your scans. To be safe, you can scan all your photos at DPI. This will give you an exact copy of your original photo.
If you're scanning more than DPI you're just scanning the surface of your photo. You'll only scan more artifacts off the photo-- such as the gloss off the photo, minute dust and debris, etc.
You are not going "deeper" and scanning more pixels and image detail. That's because your physical photo has a limit of DPI. It was printed using dots per inch. Jason, a recent customer, came to me with photos. It was his Mom and Dad's 60th Anniversary, and he wanted to make a slide show for the party. He told me that he was going to display the digital images on a large projection screen. I told him that a DPI scans will display perfectly on any size screen. Even a 8' x 8' projection screen.
How can a 4" x 6" photo scanned at DPI be displayed on a 8' x 8' projection screen, at excellent quality? When you setup your scanner at DPI, what it does is it "squeezes" dots pixels per inch.
In other words your scanner multiplies the height and width by the amount of resolution you chose. Here's what happens to a 4" x 6" photo scanned at DPI This number x is called the dimension. And it's the MOST important number you need to know. Forget about DPI, mega pixels, 4K. Dimension is most important. Here is why To put this number in perspective, have a look at your p HDTV.
The dimension of your HDTV is x Now, your digital photo is x That is because the dimension of your photo is pretty close to your HDTV resolution. Check it out Oh, and what if you have a projection screen? Well, if you look at the specs of your projection screen it is probably x as well.
And even if you watched your digital photos on a 8' x 8' projection screen, it will still display at x It is the same with an HDTV. Well, the same thing happens.
Your scanner will squeeze multiply dots for every inch. What happens is Your 4" x 6" photo is converted into a x digital photo. Does this mean when you play this digital photo on your HDTV it will be twice the quality? Your HDTV has a display limit of x If you your digital photo is larger than that, two things can happen. One, your HDTV will crop your photo.
Or two, it may re-size back down to x When you scan you photos at DPI, you are not picking up any more detail off your photo. You are just making it bigger. You're not getting any more detail. Yeah, the the TV is bigger, but the dimension x is still the same. But if you get a 4K TV, then you'd get more detail. What your scanner did was make sure to add enough extra pixels to maintain the same quality of the DPI digital photo, not add more pixels for extra detail.
The same thing happens when you have a 32" HDTV vs. You're not getting more picture quality. You just make sure you maintain the same quality when you have a larger screen size. At DPI you will get a digital photo with a dimension of x And I know that I will pickup a lot of artifacts like finger prints, etc.
And it's better to have too many pixels, than too little! Remember my customer Jason? He wanted photo scans so he can display them on a 8' x 8' projection screen.
I told him DPI will do the job. So naturally, Jason thought since the images can be displayed at excellent quality on a projection screen, he can also make poster size prints.
When he took one of his DPI photo scans, and had the print shop make a 12" x 18" re-print, the poster looked horrible. How can the same digital image look great on a 8' x 8' projection screen, but when printed out at 12" x 18", it comes out looking horrible?
Remember, your photo scanned at DPI will be the exact same size as your original. And if you try to take that DPI photo scan and re-print it at double the size, it will turn out pretty bad. If you want to re-print your 4" x 6" photo at 8" x 12", you'll need to double your DPI to If you want to print your 4" x 6" photo to 16" x 24", you'll need to use DPI.
I just want to show you that at DPI you'll be safe at displaying your scans on any digital screen. But if you want to make physical re-prints, you'll need to use more DPI. And here's another reason to use more than DPI. I rather have too many pixels than too little. Maybe in five years they will come out with a p HDTV!
I'll be ready. And they did come out with a bigger TV Also, I can always make a copy of my DPI photo scans, and re-size the copies to whatever I want to do. If my HDTV is cropping my x digital photos, I just make a copy and re-size the copies to x The same math applies. Say you have a 2" x 2" photo. Here is what happens when you convert it to a DPI digital photo So now you have a digital photo that is x way below your HDTV dimension. So in this case you probably would want to scan it at DPI.
Check out what happens And that is the point here-- once you understand how resolution works, then you have more control. You can scan all your photos at DPI and archive them. Hey, my name is Konrad.
