4,000 PPI or DPI

Our normal scanning resolution for your 35mm slides and films is 4,000 pixels per inch. Could you settle for less? Maybe. Should you settle for less? Its up to you. Our standard service scanning at 4,000 ppi includes expert Photoshop editing by one of our highly trained Photoshop Artists.

Just a note: Some people say DPI, which is taken from the printing term of "Dots Per Inch" which are actual dots on a printing plate. Since we are talking about digital images here, which have pixels and not "dots", we use the correct terminology of "Pixels Per Inch." Just a small technicality. We know what you mean if you say DPI, so don't worry about it.

Question: What would be an advantage of scanning at 4000 ppi instead of a lower resolution?

Answer: You will be getting more detail in your image. If you want to blow it up, you will be able to blow it up to a much higher size.

 

Pixels and megapixels:
Pixels are the basic building blocks of every digital image; the more pixels in your photos, the better the Print appearance.

A megapixel means one million pixels and is the unit of image-sensing capacity in a digital camera, or the amount of information the camera can capture. Generally, the more megapixels a camera has, the better the print resolution will be.

An image that is 1024 x 768 at 100 PPI is the exact same file and has the same resolution as an image that is 1024 x 768 at 500 PPI. Both files contain a total of 786432 pixels in a grid that has 1024 pixels on one side and 768 pixels on the other side. A more reliable measure for digital photo-finishing is the actual resolution, which represents the number of pixels that make up the image.

We scan at 4,000 pixels per inch and our 35mm slide scanned images have a total of 5,256.00 X 3,544.00 = 18,627,264 pixels.
