Image quality is very important at DiscountDigitalArt.com. We use the finest film scanners and photo scanners available and our slide scanning technicians and the digital editors, are well trained imaging professionals who understand digital imaging. The technical specs for our slide scanning and film scanning vary depending on the scanning level. Below is a breakdown of how the different scans stack up:

Resolution (dpi aka ppi)	Standard 35mm Slide Scanning 2000	Deluxe 35mm Slide Scanning 3000	PRO 35mm Slide Scanning 4000
Megapixels	5.7	8.8	22.8
Pixel Dimensions	2892 x 1974	3600 x 2450	5782 x 3946
DigitalICE4 Settings	On/ Normal	On/ Normal	On/ Fine
Borders Cropped	No	Yes	Yes
Rotation Correct	Yes	Yes	Yes
Multisampling	Yes 2x	Yes 4x	Yes 8X
Ave. Jpeg Size	1-2MB	2-4MB	9MB
Ave. Tiff Size	16MB	20MB	40MB
Bit Depth	8	8-24	8-24
Colorspace	sRGB	sRGB	sRGB

Any of these specifications can be modified based on special requests. If you need CMYK or some specific color space for your printing needs we can produce your images with a different colorspace.

Multisampling: When a slide scanner or film scanner scans a slide or negative in one pass this can be called a single sample scan. In otherwords, the scanner looks at each pixel location once and determines the correct color for that pixel and records that information. When a scanner is utilizing its multisampling feature it is looking at each pixel location more than once and the scanner software compares and averages the color of each pixel from the multiple times it was sampled. It could be compared to weighing yourself on a digital scale, if you weigh in once you might see 154.5 lbs, then if you weigh in again you might see 154 lbs. Let's assume that in reality your weight is exactly 154.25, but the digital scale has to round either up or down to the nearest half pound. If you just weigh in once you will either see 154.5 or 154, either way you are off by a quarter of a pound. If you weighed in four times and averaged the results you would likely see a result much closer to your actual weight of 154.25. This is the benefit of multisampling with the film scanner. It is like scanning each slide two or four times and then averaging the results of the scans to create a more perfect image.

Colorspace: The colorspace of your scanned picturers refers to the specific mathematical model used to interpret the millions of color variations that you see in your photos. Image colors are created by combining either three or four base colors in a certain combination similar to how a paint mixer at your local home improvement store can make any of thousands of specific colors by combining a few drops of a few different color pigments. Your computer monitor combines Red, Green and Blue to make all the colors you see, this is an example of an RGB colorspace and is the most common colorspace used in digital imaging. This is our standard colorspace for 35mm slide scanning, 35mm negative scanning and photo scanning. However, most printers create the range of colors using a 4 color colorspace. They combine Cyan, Magenta, Yellow and and Black to create all the color variations. This is known as the CMYK colorspace. Some photographers need us to scan their slides, negatives and photos in the CMYK colorspace. Publishing houses often need CMYK colorspace because they are involved in printing magazines and other publications and their printers use CMYK. We use high end professional film scanners and we can scan to any of the major colorspace variations.
