What Can You Do With A 9 Mega Pixel Slide Scan
DPI: 3000 DPI
Dimension: ~3900 x 2500
File Size: ~2 MB, JPEG File
So, what do all these numbers mean? And what can you do with that?
Customers who chose 3000 DPI / 9 Mega Pixel slide scans, used them to view them on their HDTV.
And the small file size means that you can upload the files quickly to the net.
To put it in perspective, have a look at your 1080p HDTV. The "dimension" of your HDTV is
1080 x 1920. Have a look...
No matter if you have a 32" or 52", all 1080p HDTV are 1080 x 1920
And when I scan your slide at 3000 DPI, you get a digital image of 3900 x 2600. Here's what happens when when yoru slide is converted to digital...
And the result is...
This means a 3000 DPI scan will be displayed at full HD.
How do you get 9 mega pixels? Well, multiply the dimension: 3900 x 2500 = 9 million. Or in marketing terms, that's 9 mega pixels.
If you ever wanted to produce a physical print, you could go as high as 12" x 18", at excellent quality.
18 Mega Pixel Slide Scans Were Designed For True Digital Archiving
DPI: 4000 DPI
Dimension: ~ 5400 x 3400
File Size: 4 - 10 MB, JPEG File
This option was designed for you if you want the highest resolution possible.
Think of it this way: remember when you had to replace your VHS tapes to DVD, or cassette tapes to CD?
Well, at 4000 DPI, you won't have to worry about replacing your scans in the future. You scanned them right, the first time.
And someday when you have grandchildren, know that at 4000 DPI your slide scan won't be out-dated.
You also have flexibility. Some customers make copies of their 4000 DPI scans. And with the copies, they size the images down to 3000 DPI. They will always have the 4000 DPI scans as a back-up. And use the 3000 DPI copies to share on the internet, or make DVD slide shows.
So, what do all these technical specs mean?
When your slides are scanned at 18 mega pixels, you will get a digital image that is 5400 x 3600 or 18 mega pixels (5400 x 3600 = 18 million).
Here's what happens when your slide is scanned at 4000 DPI...
And your result is...
A 35mm slide scanned at 4000 DPI gives you a digital image of 5400 x 3600.
If you ever wanted to print these slide scans, you could produce a print that is 24" x 36", at excellent quality.
TIFF Slide Scans Are Designed For Museum Quality
DPI: 4000 DPI
Dimension: ~ 5200 x 3400
File Size: 100 - 500 MB, TIFF File
The difference between the JPEG and this TIFF scan, is the TIFF scan is 100 MB. At a 100 MB file size, your slide scans can be printed at billboard size.
TIFF slide scans are usually requested by professional photographers, museums, educational institutions, or commercial magazines.
However, if your concern is the highest possible resolution and quality, I recommend TIFF scans.
To download a TIFF slide scan, please contact me and make a request.
Number 1 Myth About Resolution: High Resolution Means High Quality
Please don't mistake resolution with quality. Resolution is just bits and bytes. It's what you do with the bits and bytes AFTER, that determines quality.
True - at ScanCanada.ca your slides are scanned at the highest resolution possible.
But to get quality images, my tean and I edit your slide scan in Photo Shop. We don't rely on short-cuts like Digital ICE to edit your scans. Editing is done professionally, by an actual person. Not by a machine.
