Slide, Film, Photo Scanning Resolution: UTILIZE THIS DPI TO OBTAIN HD Quality Digital Images

Read this first if you’re unsure what resolution you will need for HD slide, photo, and film scans.

Understanding resolution is simple to grasp once you learn these 3 basic numbers. As soon as you know the fundamentals of image resolution, the simpler your scanning project will undoubtedly be. Let’s begin.

1. Know THE INITIAL Size OF ONE’S Slide, Negative And Photo

The initial number you should know may be the actual size of one’s negative, slide, or photo. Knowing this number is essential because it may be the very first thing your scanner talks about.

Remove a 35mm negative or 35mm slide, and when you truly measure it, the physical size is approximately 0.80″ x 1.30″. The photos in your loved ones albums are likely 4″ x 6″ or 8″ x 10″. Older photos can range between 2″ x 2″ to 3″ x 5″.

Whenever your scanner software begins, search for something called “Original Size”. That’s where your scanner will determine how big is your original. Which means that your 4″ x 6″ photo may show as 3.9″ x 5.9″. Usually do not worry if it’s nearly 4″x6″, you will see some cropping.

2. Dots Per Inch — WHAT’S DPI And JUST HOW MUCH SHOULD YOU Scan Slides, Negatives, And Photos

Dots per inch is really a term that originates from the times of photo labs. Remember the method that you had to get into an image lab to build up your photos? The actual lab did was they printed 300 colored dots onto photo paper. Which means that your 4″ x 6″ photo had 300 dots per inch that composed your image. Slides and negatives certainly are a bit different. Rather than colored dots, emulsion can be used to coat transparent film.

ONCE I scan my photos I take advantage of 300 DPI, as well as for slides and negatives I take advantage of 1500 DPI. As of this DPI you’ll be safe as you will create a digital image that’s A similar quality and detail as your original.

When you open your scanner’s software you will notice two numbers: 1. Original Size: again, this is actually the actual size of one’s original, give or have a few points. And #2 2. can be your DPI: that’s where you select what resolution you intend to scan your slide, negative, or photo.

Now, both of these numbers, come up with, can make up your digital image. Here’s how:

3. How Original Size And DPI INTERACT AND PRESENT You AN ELECTRONIC Image

Say you’re scanning a 35mm slide. Your scanner will highlight a genuine Size is 0.85″ x 1.30″ (give or take). Then search for your DPI or Resolution, and input 1500. What your scanner does with one of these numbers is merely multiply them. Which means that your 0.85″ x 1.30″ slide is multiplied by 1500 DPI, gives you 1275 x 1950. Here’s another look: 0.85″ x 1500 DPI = 1275, and 1.35″ x 1500 DPI = 1950.

Now have a glance at your photo. Remember it really is 4″ x 6″, and you also desire to use 300 DPI. Here’s what your scanner does: 4″ x 300 DPI = 1200, and 6″ x 300 DPI = 1800.

This number you obtain (1275 x 1950) is named Pixel Dimension. Can you see some similarities having a slide scan and an image scan? You scanned your slide at 1500 DPI as well as your photo at 300 DPI, nevertheless, you still have exactly the same Pixel Dimension. Here’s another look: 35mm slide scanned using 1500 DPI = 1275 x 1950 Pixel Dimension; 4″ x 6″ photo scanned using 300 DPI = 1200 x 1800 Pixel Dimension.

For this reason the specific size of one’s original is essential, and DPI isn’t. You used two different DPI’s, but nonetheless got exactly the same result– an electronic image that’s about 1200 x 1800. But is 300 DPI / 1500 DPI enough to offer an excellent digital image?

Conclusion: 1200 x 1800 Pixel Dimension OFFERS YOU True HD Quality

To place everything in perspective, browse the Pixel Dimension of one’s computer monitor (it really is called Screen Resolution). The dimension of my computer monitor is 1366 x 768. Now have a look at an iPad. The dimension of this is 1024 x 768. Lets move on your 52″, 1080p HDTV. The specific dimension of one’s HDTV is 1080 x 1920.

Do you note that even your HDTV includes a pixel dimension that’s somewhat less than your 1200 x 1800 digital photo? Which means that your 1500 DPI slide scan, as well as your 300 DPI photo scan will undoubtedly be displayed at full HD quality. That’s as the pixel dimension of one’s scans are larger than your HDTV.

But this is actually the thing: I scan my slides at 4000 DPI and photos at 900 DPI. Why? Despite the fact that 1200 x 1800 is really a safe resolution, you won’t ever know very well what future technology should come out with. Which is always easier to have way too many pixels than not enough.
